Full textMikania glomerata Sprengel and Mikania laevigata Schultz Bip, (Asteraceae, Eupatorieae, Mikaniinae), commonly known as guaco, have been studied because of their medicinal activities. They are used to treat fever, rheumatism, flu and respiratory tract diseases. The monographies of both species are found in Brazilian Pharmacopoeia. For many times, M. laevigata is confused with M. glomerata, and it has been sold as the last. This occurs mainly at the south of this country, where this plant has been found. In spite of the important medicinal uses from M. laevigata, the literature has few studies about its phytochemistry. In this work, the phytochemical study from the dried leaves of M. laevigata was proposed and the compounds lupeol, taraxerol, coumarin, orto-[(5-hydroxy)-cis-cinnamoyl]-transcinnamic acid, syringaldehyde, trans-melilotoside, cis-melilotoside, methyl 3,5-di-O-caffeoyl quinate, 3,3,5-trihydroxy-4,6,7-trimethoxyflavone, patuletin 3-O-b-D-glucopyranoside, quercetin 3-O-b-D-glucopyranoside, kaempferol 3-O-b-D-glucopyranoside, adenosine, entkaurane- 3a,16b,17 triol 3-O-b-D-glucopyranoside and 19-norkaur-16-ene-18-oic acid, 2b- [[3-O-(3-hydroxy -1-oxo -3 phenypropyl ) - 2 - ( 3- methyl - 1- oxobutyl - 4 - O - (a - Lramnopyranosyl) - b- D-glucopyranosyl]oxy]-13,15a-hidroxy were isolated and identified by spectroscopic methods. The compounds beyerenoic acid, kaurenoic acid, caryophyllene oxide, spathulenol dihydrocoumarin, and lupeol acetate were also identified, by GC-MS. It was proposed the chemical evaluation from the leaves rinse extracts of M glomerata and M. laevigata too. In the quantitative analysis of these extracts, coumarin and lupeol were identified as the main compounds of M. laevigata and lupeol and an unidentified compound of M. glomerata. The standardization of the analytical method by GC-MS allowed to differentiate one species from the other. Thus, leaves of guaco from many places of this country were used, and their identities were proposed.

Full textWe present in this thesis some improvements of acoustical pressure prediction by ray-based methods involving curved surfaces. The framework is an adaptative beam tracing algorithm. The first part deals with diffraction by obstacles. First we solve the problem of successive wedges diffractions. Then we extend this problem to creeping waves calculation on curved surfaces using an appropriate and frequency independant tesselation of these surfaces. The reconstruction of continuous and derivable surfaces from meshes to improve reections computation is treated in the second part. These surfaces have to be suitable for ray tracing technics. Starting from Powell-Sabin splines we extend its use to any kind of surfaces. This implies different projection planes that creates holes on the surfaces. We show that these gaps can be filled with polynomial implicit surfaces of degree four ; consequently their intersections with rays can calculated analytically

Full textMikania smilacina DC, which is commonly known as \"guaco-de-sete-sangrias\",was described pharmacognostically. It has been applied in folk medicine as an antiinflamatory teething agent, in treatment of hypertension, urticaria and for its diuretic properties. The external and internal plant and drug morphology has been studied here in detail. Some illustration is made with pictures and photos of many structures. Chemical studywas made isolating and identifying components of the hexanic extract prepared from the plant. In this manner a kaurenoic acid, a pimaradienic acid.and coumarin has been found in the extract of the plant. Gas chromatography analysis followed by the identification of the components by mass spectroscopy connected to a databank detected the presence of the following components: alfa-pineno; sabineno;limoneno; alcool alfa 4-dimetil benzílico; derivado dimetilado do estireno; terpinoleno; biciclo(6.1.0) nonano, 9-(1- metiletilideno); ciclo-hexeno1,5,5-trimetil-6-(2-propenilideno); ciclo-hexeno,1- (propinil); 2H-1,6 benzoxazocin-5-(6H)ona, 3,4-dihidro; 2(1A) azulenona, 4,5,6,7,8,8a-hexahidro-8a-metil; etanona, 1 octahidro-3-hidroxi-7a-metil-5- (1metil- etenil); 2,6,10 dodecatrien-1-ol,3,7,11-trimetil; 1- heptanol, 2 propil; 1-noneno, 4,6,8- trimetil; espiro(4,5) dec-7-eno,1,8-dimetil-4-(1-metiletenil); 3-metil - 1,4-heptadieno; metilester do ácido 2-metil octanóico; 2,4,4-trimetil hexano; ciclopentano, 2-metil-1-metileno-3-(1-metiletenil); 2-metil, undecano; 4-metil-2-propil 1-pentanol; 3-etil, 3-pentanol, octadecano, N-etil acetamida, Hexatriacontano, 2-metil dodecano; 3-3-dimetil heptano. Quantification of coumarin by thin layer chromatography followed by densitometry of the fluid extract has also been made and the concentration of the substance in the plant varies from 0,032 to 0,035 % m/v. The chromatographic profile of the fluid extract was better characterized when using a 20% sodium hydroxide solution as the revealer reagent. The anticoagulant, antiinflamatory and antimicrobial activity as well as its subagude toxicity has also been tested. The plant does not seem to present antiinflamatory or anticoagulant activity, and only low antimicrobial activity against Staphyloccocus aureus. The subagude toxicity assay of the extract showed no intoxication signals when using doses up to 100mg/kg.

Resumo: No Brasil, as espécies Mikania glomerata e Mikania laevigata, conhecidas popularmente como guaco, são muito utilizadas na forma de xarope devido ao seu efeito broncodilatador. A comercialização de medicamentos fitoterápicos no Brasil é regida por diversas legislações que primam pela qualidade destes, porém a qualidade da matéria-prima pode interferir de forma fundamental na segurança e eficácia do medicamento. Diante disso, este trabalho realizou um estudo de estabilidade do extrato hidroalcoólico das espécies citadas, conforme preconiza o "Guia para a realização de estudos de estabilidade de medicamentos" publicado pela ANVISA na RE 01, de 29 de julho de 2005. Folhas das duas espécies de Mikania foram secas em estufa a 40 °C e em liofilizador, foram preparados extratos hidroalcoólicos por maceração, que foram submetidos a estudo de estabilidade acelerado por 6 meses, e estudo de estabilidade de longa duração por 12 meses. As amostras ficaram armazenadas em diferentes temperaturas (22°C, 30°C e 40°C), com e sem incidência de luz, e a cada 3 meses foram analisadas por UHPLC-MS, para acompanhar seu perfil químico, quantificar a cumarina e ácido clorogênico. Em todas as condições do estudo, observou-se uma redução do teor do marcador químico desta espécie, a cumarina, maior que 5 %, sendo assim, não é possível atribuir o prazo de validade de 2 anos para extratos hidroalcoólicos desta espécie
Abstract: In Brazil, the species Mikania glomerata and Mikania laevigata, known popularly as guaco, are widely used in syrup form due to its bronchodilator effect. The marketing of herbal medicines in Brazil is governed by various laws that guarantee the quality of these, but the quality of the raw material can interfere, fundamental safety and efficacy. Therefore, a stability study of the hydro alcoholic extract of the species mentioned was conducted as recommended by the "Guidelines for conducting stability studies of drugs" published by ANVISA in RE 01 of July 29, 2005. Leaves of both species of Mikania were dried in an oven at 40 ° C and by freeze drying, hydro alcoholic extracts prepared by maceration, which underwent accelerated stability study of 6 months, and long term stability study for 12 months. Samples were stored in different temperatures (22 ° C, 30 ° C and 40 ° C) with and without incident light, and every 3 months were analyzed by UHPLC-MS to monitor their chemical profile, quantifying coumarin and chlorogenic acid. At all conditions of the study, we observed a reduction of the content of the chemical marker of this species, coumarin, greater than 5%, so a shelf life of 2 years cannot be assigned to the hydro alcoholic extracts of these species

Full textMikania is the largest gender of the tribe Eupatorieae, with about 430 species, being distributed thoroughly in Brazil, with approximately 200 described species. In this gender, Mikania cordifolia, M. micrantha and M. glomerata are commonly called \"guaco\" and are among the more popularly used species, mainly for the treatment of fever, rheumatism, diseases of the breathing tract and against snake bites. In the present work, phytochemical studies of these three species were carried out and the effects of the fertilization types, the solar radiation and the hydric stress upon the production of secondary metabolites were analyzed. Firstly, through phytochemical studies, 62 compounds were identified. The polar fractions of the species presented as majority compounds phenylpropanoic derivatives: 3,5-Dicaffeoylquinic acid in M. glomerata and M. micrantha and Fertaric acid in M. cordifolia. In M. glomerata were also identified glucaric acid derivatives di- and tri-esterified with cafeic acids, which are no described in the literature until the moment, besides sulfated flavonoids, which are also present in M. micrantha. In the apolar fractions the triterpenes presence were verified mainly in M. cordifolia and kaurenoic acid derivatives in M. glomerata and M. micrantha. The sesquiterpene lactones were found in M. cordifolia (melampolide skeleton) and in M. micrantha (micranolide skeleton). The analysis of M. glomerata and M. cordifolia cultivars revealed a great influence of the cultivation conditions in the secondary metabolites composition. The experiments showed a great variation among the concentration of the compounds in the two species of Mikania, being verified that the cultivation conditions and mainly the taxes of solar radiation are of extreme importance in the accumulation of these metabolites. The hydric stress didnt have significant effects in the accumulation of substances in M. glomerata. The histochemical analyses were effective in supply information regarding location of phenolic compounds in the leaves of M. glomerata.

Full textIn this study the ethanolic extracts from the species Mikania parodii Cabrera and Mikania pilosa Baker were obtained and fractionated by vacuum liquid chromatography, column chromatography and size-exclusion chromatography. From the species M. parodii were isolated and identified through the comparison of the 1H and 13C NMR spectral data with those in the literature the triterpenes taraxasterol acetate, pseudotaraxasterol acetate and the flavonoids kaempferol-3-O-glucoside and quercetin-3-O-glucoside. From the species Mikania pilosa was isolated the flavonoid quercetin 7-methyl ether. The extracts and fractions of both plants were analyzed by hyphenated techniques (GC-MS and LC-MS/MS), allowing the identification of 46 compounds in M. parodii and 60 compounds in M. pilosa, comprised the classes: monoterpenes, sesquiterpenes, diterpene (M. pilosa), triterpenes, flavonoids, quinic acid derivatives (chlorogenic acids), fatty acids and esters. The ethanolic crude extract of M. pilosa, ressuspended in water:ethanol (7:3) inhibited more than 50 % and 59% respectively the HCT-8 (colon carcinoma) and SF925 cells (human glioblastome). The analysis of polar extracts of the M. camporum and M. vitifolia species in LC-MS/MS in comparison with literature allow the identification of quinic acid derivatives: 5-O-caffeoylquinic acid; 3,5-di-O-caffeoylquinic acid; 4,5-di-O-caffeoylquinic acid, methyl and O-glucosylflavonoids in both species.

Mikania (Eupatorieae, Asteraceae) é um dos maiores e mais comuns gêneros de trepadeiras neotropicais. Seu principal centro diversidade inclui a região dos estados de Minas Gerais e Rio de Janeiro, estendendo-se até o Paraná e Santa Catarina. Em 2003 e 2004, estudei a fenologia reprodutiva, a morfologia e a biologia floral e os visitantes florais de duas espécies co-ocorrentes, Mikania glomerata Spreng. e M. hirsutissima DC.. O Trabalho de campo foi conduzido na Estação de Pesquisa, Treinamento e Educação Ambiental Mata do Paraíso, em Viçosa, Minas Gerais (20°45’S, 42°54’W). Essas duas espécies ocorrem no Brasil, de Minas Gerais ao Rio Grande do Sul, na Argentina e no Paraguai. No local de estudo, plantas individuais crescem em áreas abertas, como a borda da floresta e clareiras, e sobre a copa de árvores. Os capítulos de Mikania possuem quatro flores, quatro brácteas involucrais e uma bráctea sub-involucral. Na Mata do Paraíso, Mikania glomerata e M. hirsutissima tem um período de floração que vai de agosto à setembro (fianla da estação seca)e o comportamento de floração e frutificação, destas espéceis pode ser classificado como “anual- intermediário”. Em M. hirsutissima, as brácteas sub-involucrais e as involucrais de protegem os botões e as flores e também servem para atraír polinizadores e auxiliar na dispersão. Todavia, em M. glomerata, a função dessas estruturas esta restrita à proteção do ovário e ajuda na dispersão. Nas duas espécies, a antese ocorre pela manhã, das 7h:00 às 9h:00. As flores são protândricas e duram de quatro a 13 dias. Três movimentos, dois destes servem para expor grãos de pólen para os vissitantes, caractreriza a fase masculina; há um mecanismo do tipo escova de apresentação secundária de pólen. Quatro movimentos dos ramos do estilete, caracteriza a fase feminina, que é longeva em relação à masculina. Insetos visitaram os capítulos durante a fase feminina, quando reportei: (i) anteras pigmentadas; (ii) perfume; (iii) nectários ativos; e (iv) fendas aumentando progressivamente entre filetes adjacentes. O nectário, que é pistilar e persistente, facilita a dispersão anemocórica dos diásporos (outubro-novembro). Ambas as espécies são entomófilas generalistas, embora abelhas sociais tenham sido os principais polinizadores
Mikania (Eupatorieae, Asteraceae) is a common and large genus of Neotropical vines. Its major center of diversity includes Southeastern-Southern Brazil, from Minas Gerais and Rio de Janeiro to Paraná and Santa Catarina states. During 2003-2004, I studied reproductive phenology, floral morphology, floral biology, and visitors of two co-occurring species, Mikania glomerata Spreng. and M. hirsutissima DC. Fieldwork was conduced in the Estação de Pesquisa, Treinamento e Educação Ambiental Mata do Paraíso, Viçosa, Minas Gerais (20°45’S, 42°54’W). These two species occur in Brazil, from Minas Gerais to Rio Grande do Sul, Argentine and Paraguay. In the study area, individual plants of both species grown in open sites, like forest edges and clearings, and over tree crowns. Mikania sustains 4-flowered heads, with four involucral bracts and one subinvolucral bract. In the Mata do Paraíso, Mikania glomerata and M. hirsutissima has a flowering period that goes from August to September (late dry season); the flowering and fruiting behavior of these species can be assigned as “annual-intermediate”. In M. hirsutissima bracts protected the flowers and flower buds and also served to attract pollinators and aid dispersal. However, in M. glomerata the function of these structures is restricted to protect the ovary and aid dispersal. In both species, anthesis occurs at morning, from 07h00 to 09h00. The flowers are protandrous and last ca. 13 days. Three movements of style, two of which serve to expose the pollen grains to visitors, characterize male period; there is a brushing mechanism of secondary pollen presentation. Four movements of style arms characterize female period, which is longer than male period. Insects visit the heads during female period, when I also reported: (i) pigmented anthers, (ii) scent, (iii) nectary activities, and (iv) crevices progressively enlarged between adjacent filaments. The nectary, which is pistillate and persistent, facilitate the anemochory dispersal of diaspores (October-November). Both species are generalist entomogamous, although during this study the major pollinator were social bees.

Full textThis work describes the chemical study of two plants which belong to the family Asteraceae: Mikania sp. nov. and Wunderlichia crulsiana. The dichlorometane extracts from leaves and stems of Mikania sp. nov. we studied and seven diterpenic acids were isolated and identified. The volatile oil from leaves and stems of this plant were also studied and twenty substances among monoterpenes and sesquiterpenes were identified. From Wunderlichia crulsiana we analysed the dichlorometane extracts from flowers and stems. From flowers we isolated and identified triterpenes esterified with palmitic acid and acetic acid. From stems we isolated and identified triterpenes esterified with acetic acid and 3-oxo-triterpenes. By GC, we identified hydroxylated triterpenes that were acetylated, and triterpenes esterified with palmitic acid that were hydrolysed and acetylated. From stems we also isolated and identified three sesquiterpene lactones and a sesquiterpene. The compounds were identified by PMR, CMR (BBD and DEIT 135º), GC/MS and co-injection with authentic samples The extracts of both plants showed low activity when submitted to bioassay with Cladosporium sphaerospermum. The fractions which contain the hydroxylated triterpenes, triterpenes esterified with acetic and palmitic acids and sesquiterpene lactones were submitted to anti-inflammatory bioassay and showed 42%, 29%, 29% and 47% of activity, respectively. The above mentioned extracts and the fractions did not show significant activity on the Saccharomyces cerevisae bioassay, so there were not citotoxic substances in them.

Abstract: Native to the Atlantic forest of Brazil, and Mikania glomerata Spreng and Mikania laevigata Schultz. Bip. ex Baker, are commonly known as guaco, and widely used for respiratory system disorders. Coumarin contributed to pharmacological effect along with other chemicals in these species. The chemical composition of a plant is influenced by various abiotic factors, nutrition requires emphasis, because the deficiency or excess biomass production and undermine the content of secondary metabolites. Thus, the work aimed to evaluate the effects of the levels of N, P and K from the poultry litter, productivity and coumarin content of two species of guaco M. glomerata and M. laevigata. The study was conducted in Fazenda Experimental Lageado, da Faculdade de Ciências Agronômicas - UNESP, Campus de Botucatu-SP. The experimental design used was the completely randomized design with five treatments and four replications, treatments consisted of NPK formulations ((T1= 0-0-0; T2 = 120-120-100; T3 = 240-240-200; T4=360-360-300; T5= 480-480-400 kg. ha-1). At the end of the experiment were evaluated: fresh and dry biomass of shoot and root, plant height, leaf area, leaf number, length and volume of the root, SPAD index, content of macro and micro-nutrients from the leaves of guaco, besides the coumarin content. The data were submitted to analysis of variance and the variables that showed significant differences regression analysis was performed, the Pearson correlation was used to relate the coumarin content with foliar nutrients.

Resumo: O uso de plantas medicinais vem crescendo nos últimos anos e isto é devido principalmente as descobertas de suas propriedades biológicas, e entre estas plantas destacam-se as do gênero Mikania. Assim, a procura pela descoberta de novos produtos naturais com atividade antibacteriana para a prevenção de doenças bucais e talvez com menores efeitos adversos quando comparados aos produtos industrializados seria muito importante para obtenção de um meio efetivo de controle da formação de um biofilme patogênico. Assim, em estudos anteriores, a fração hexânica das plantas Mikania laevigata e Mikania glomerata apresentaram atividade antimicrobiana e inibiram a aderência dos estreptococos do grupo mutans. Deste modo, o objetivo geral deste trabalho foi avaliar o efeito antimicrobiano dos compostos isolados das frações hexânicas das plantas M. laevigata e M. glomerata (guaco) sobre os estreptococos do grupo mutans. Para isso, foram realizados três estudos, sendo o objetivo do estudo 1 analisar a composição química e o efeito antimicrobiano dos compostos isolados e identificados das frações hexânicas das plantas M. laevigata e M. glomerata sobre o crescimento bacteriano e a aderência celular dos estreptococos do grupo mutans. O objetivo do estudo 2 foi determinar a influência destes compostos isolados na formação e na composição de polissacarídeos de biofilmes de Streptococcus mutans UA159 formados em discos de hidroxiapatita, na queda de pH gücolítico e seu efeito na translocação de prótons pela atividade da ATPase. Além disso, foram realizados estudos para analisar seu efeito na atividade de glucosiltransferase (GTF) B em solução (GTF-sol) e em superfície (GTF-sup). O objetivo do estudo 3 foi avaliar as atividades dos compostos isolados da Mikania utilizando modelo experimental de cárie em ratos. No estudo 1, os ácidos cupressênico, diterpênico e caurenóico foram os compostos que apresentaram atividade antimicrobiana (CIM entre 2,5-20 ng/mL e CBM entre 2,5-40 jjg/mL) e inibição da aderência celular entre 1,25-5 ug/mL, sendo que os compostos espatulenol, caurenol, ácido grandiflórico não apresentaram atividade biológica nas concentrações testadas. No estudo 2, somente os três compostos ativos isolados da Mikania foram avaliados na concentração 500 }ig/mL. Os resultados demonstraram que os ácidos cupressênico, diterpênico e caurenóico apresentaram efeito na viabilidade bacteriana dos biofilmes, reduziram a produção de ácidos orgânicos (pH final entre 6,4-5,8) e a atividade da ATPase (28-40%). Os compostos também foram potentes inibidores da atividade de GTFs, tanto em solução quanto em superfície de hidroxiapatita, sendo 50-60% de redução para GTF B-sol e 50-80% de redução para GTF B-surf. Nos biofilmes, o peso seco e a quantidade de polissacarídeos solúveis, insolúveis e intracelulares também foram significativamente reduzidos com o tratamento dos três compostos (p<0,05). No estudo 3, a aplicação tópica 2 vezes ao dia dos ácidos cupressênico, diterpênico e caurenóico (500 ug/mL) promoveu a redução na incidência de cárie em superfície lisa e sulcai (p<0,05), além da diminuição na porcentagem de infecção por S. mutans UA159 pelos ácidos diterpênico e caurenóico, não sendo afetada a microbiota total dessas ratas. Desta brma, concluímos que os ácidos cupressênico, diterpênico e caurenóico isolados da M. laevigata e M. glomerata possuem potencial antimicrobiano, inibindo os fatores de virulência dos Streptococcus mutans e a cárie em modelo in vivo, demonstrando serem promissores agentes anti-cárie e antí-placa
Abstract: Considering the great use of plants as medicinal substances in the popular medicine, it is critical to investigate their biological and chemical properties in order to not anly help to enhance our understanding of the therapeutic potential of these natural products, but also how to make them more effective pharmacological agents. The development of therapeutic agents aimed at disrupting both colonization of the teeth by dental pathogens and the subsequent formation of dental plaque is one of the prime strategies to reduce the incidence of tooth decay. The hexanic fraction of the plants Mikania laevigata and Mikania glomerata showed antimicrobial activities and inhibit the adherence of mutans streptococci. The overall aim of this study was to evaluate the antimicrobial effect of the isolated compounds of the hexanic fractions of Mikania laevigata and Mikania glomerata (guaco) on mutans streptococci. Therefore, three studies were carried out. in study 1 ,the antimicrobial activity of the isolated compounds was assessed by determination of minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and inhibition of cell adherence (Adh) to glass surface of mutans streptococci. In study 2, the influence of the isolated compounds were evaluated on viability, development, polysaccharide composition and acidogenicity of S. mutans biofilms, on glucans production by purified glucosyltransferases (GTFs) adsorbed to hydroxyapatite beads, and on membrane-associated F-ATPase and glycolytic activities. In study 3, the influence of the isolated compounds on caries development in vivo was evaluated. The acids cupressenic, diterpenic and kaurenoic were the compounds most effective in inhibiting the growth of the bacterial strains tested (MIC 2.5-20 ug/ml and MBC 2.5-40 ug/ml) and adherence cells (1.25-5 ug/ml). These three compounds were tested on the concentration of 500 pg/ml on tne study 2, and showed antimicrobial activity reducing the viable cells and the dry-weight of the biofilm treated, and also reduced the soluble, insoluble extracellular and intracellular polysaccharide of this biofilms. The compounds were able to reduce the acid production on the biofilms (final pH between 6.4 and 5.8) and the activity of F-ATPase (28-40%). The activity of the GTF B on solution (50-60%) and on surface (50-80%) of hydroxyapatite was also reduced by the three compounds. In study 3, the topical application twice a day of cupressenic, diterpenic and kaurenoic acids (500 ug/ml) showed cariostatic effect on smooth-surface and sulcal caries, and also showing reduction of the percentage of Streptococcus mutans UA159 infection by diterpenic and kaurenoic acids (p<0.05), not showing differences on the total microbiology (p>0.05). In conclusion, the cupressenic, diterpenic and kaurenoic acids isolated from M. laevigata and M. glomerata have relevant antimicrobial activity and inhibit the virulence factors of mutans streptococci in vitro and in vivo, being promising anti-caries and anti-plaque agents

Full textNowadays, the use of medicinal plants has grown dramatically. In Brazil, a country whose native flora is rich, has invested substantially in research in this area. This is due in part to the need for new drugs, the interest in marketing these products, the interest in the preservation of popular culture and the reserve of national flora. In parallel with this scenario is the belief that phitotherapeutics are harmless in special circumstances such as pregnancy, hypertension, diabetes, etc. It is as if the herbal acted specifically in a determinate disease not on the metabolism as a whole. The Mikania glomerata Sprengel, popularly known as guaco and originating from South America, is a plant undergrowth, which rises in the forests and savannahs, and that lends itself very well to domestic cultivation. It is widely used by local people in the treatment of diseases such as asthma, bronchitis, and rheumatism, as well as having antifungal effect, antimicrobial, antiallergic, anti-inflammatory and anti-snakebite, in most cases administered without the supervision of health professionals. In this study, our goal is to study the possible action of plant extract of Mikania glomerata Sprengel (guaco) in pregnancy and reproductive profile of mice (Mus musculus domesticus) and determine whether the administration of this drug may affect the embryo / fetus and placenta during pregnancy . This study showed that the use of extract of Mikania glomerata at supratherapeutic doses can act on morphofunctional organic processes, interfering with fetal and placental growth and could lead to pregnancy failure as well as contribute to the appearance of birth defects. Furthermore, the decrease in fetal growth observed in therapeutic doses is also considered a warning to the inadvertent use of the extract guaco without medical supervision because, at any gestational period.

Full textMedicinal plants (phytotherapics) have a long history as treatments for several health disorders. In recent years, interest in the use of Mikania, a genus of the Asteraceae family, as alternative or complementary therapies for its medicinal properties has grown notably. Specifically, two Mikania species, M. glomerata e M. laevigata, widely know as guaco are used to treat fever, asthma, bronchitis and other respiratory diseases due to its content in coumarin, the main constituent of this plant. However, due to human overexploitation these Mikania species have become endangered species. The objective of the present study was to determine the optimum environment for the growth of M, glomerata and M, laevigata, by quantifying the effects of four light treatments, full sun and 25, 50 and 75% light interference and two soil nutrient conditions, fertilized and unfertilized, on the chlorophyll content, chlorophyll fluorescence, gas exchange, leaf anatomy and plant biomass production. Light irradiance levels and soil nutrient conditions significantly affected the growth and physiological responses of both Mikania species. The plants that grew in the shade presented lower photosynthetic levels, while the plants under higher radiation had larger photosynthetic rates and stomatal conductance. Light intensity reductions greater than that of 75% shade resulted in insufficient irradiation to maintain photosynthesis, influencing carbon balance and consequently leading to a decline in plant growth and productivity. The photoinhibition, evaluated at the rate Fv/Fm, occurred only in plants grown under full sun and 25% of radiation interference during the highest peak of radiation and temperature. The larger concentrations of chlorophyll, regardless fertilizing, occurred in plants under 75% of radiation interference. The thickness of the leaf blade decreased significantly with the increase of radiation interference. However, the M. glomerata leaves that were no fertilized presented, at the end of the experiment, bigger leaf blade thickness than the fertilized plants under 0 and 25% interference radiation conditions, while unfertilized M. laevigata had bigger leaf blade thickness under 25 and 50% interference radiation. The stomatal density enlarged under lower radiation interference, and in M. glomerata it was bigger in unfertilized plants. The total dry mass was bigger in plants under higher light intensity and in fertilized plants. The use of fertilizing and little protection to radiation is the best recommendation to a bigger production of dry mass, especially of leaves, that is the material used in phytotherapie. In view of the low shade acclimation capacity of these Mikania species, light intensity of cultivated areas with less than that of 50% ambient light will decrease the productivity. Thus, for agricultural purposes, in order to obtain high yields, the results of this study suggest trying to achieve approximately 25% ambient light interference with a shade net for M laevigata and indistinctively, the cultivation under full sun or 25% ambient light interference for M. glomerata.

O herpes é uma doença infecciosa, transmitida pelo vírus herpes simplex tipo I (HSV-1) e tipo II (HSV-2). A doença é caracterizada pelo aparecimento de lesões labiais (HSV-1) e genitais (HSV-2). A espécie Mikania glomerata Sprengel (guaco) é uma planta pertencente à família Asteraceae e muito utilizada na medicina popular. A cumarina, presente nas folhas de guaco, apresentam atividades biológicas decritas, tais como broncodilatadora, antiedematogênica e efeitos espasmolíticos. Este estudo teve como objetivo avaliar o efeito antiviral de extrato de M. glomerata contra o HSV-1 e HSV-2. Vale ressaltar o potencial promissor do uso do extrato seco de guaco e da cumarina 1,2-benzopirona no tratamento de infecções herpéticas, uma vez que não foi encontrado na literatura nenhum trabalho mostrando a atividade da Mikania glomerata Sprengel frente aos herpesvírus HSV-1 e HSV-2. As avaliações da citotoxicidade do extrato seco de guaco e do padrão cumarina (1,2-benzopirona) foram realizadas em culturas de células Vero (células de rim de macaco verde Africano) mediante a observação das alterações da morfologia e da viabilidade. A partir deste teste, determinou-se a concentração máxima não tóxica (CMNC). Foram utilizadas as concentrações subtóxicas do extrato seco de guaco e da cumarina 1,2-benzopirona para avaliar as atividades anti-HSV-1 e HSV-2 mediante observação da redução do título viral. Os resultados foram expressos em porcentagem de inibição (PI). O extrato seco de guaco apresentou atividade inibitória contra o vírus HSV- 1 (PI= 87,7%) e HSV-2 (PI= 92,7%). O padrão cumarina 1,2-benzopirona foi inativo contra o vírus HSV-2, mas apresentou atividade antiviral frente ao vírus HSV-1 (PI= 68,4%). Esses resultados evidenciaram a presença de outros metabólitos presentes no extrato seco de guaco que, isoladamente ou em sinergismo, contribuíram para a maior atividade antiviral. Sugere-se a incorporação deste extrato em formulações tópicas com a finalidade de proporcionar um tratamento alternativo para as infecções herpéticas.
Herpes is an infectious disease transmitted by type I (HSV-1) and type II (HSV-2) herpes simplex virus. The disease is characterized by the appearance of cold sores (HSV-1) and genital lesions (HSV-2). Mikania glomerata Sprengel (guaco) specie is a plant belonging to the Asteraceae family and is widely used in folk medicine. Coumarin, present in guaco leaves, have biological activity, such as decritas, antiedematogênica and bronchodilator effects spasmolytics. This study aimed to evaluate the antiviral effect of M. glomerata extract against the HSV-1 and HSV-2. It is noteworthy the promising potential of using guaco extract in the treatment of herpesvirus infections, since no published reports showing the activity of Mikania glomerata Sprengel against HSV-1 and HSV-2 herpesviruses were found. Cytotoxicity assessments of guaco dry extract and coumarin (2H-1-benzopyran-2-one) standard were performed in Vero cells culture (African green monkey‘s kidney cells) by observing morphology and viability. Based on this test, the maximum non-toxic concentration (MNTC) was determined. Subtoxic concentrations of guaco dry extract and 2H-1-benzopyran-2-one coumarin were employed to assess the anti-HSV-1 and HSV-2 activity by observing the reduction of viral titer. The results were expressed as percentage inhibition (PI). Guaco dry extract showed inhibitory activity against HSV-1 (PI=87.7%) and HSV-2 (PI=92.7%) viruses. The 2H-1-benzopyran-2-one coumarin standard was inactive against HSV-2 virus, but showed antiviral activity against HSV-1 virus (PI=68.4%). These results demonstrated the presence of other metabolites in the guaco dry extract that, either alone or in synergism, contributed to the higher antiviral activity. It is suggested to incorporate this extract in topical formulations for the purpose of provide an alternative treatment for herpetic infections.

Full textMikania laevigata Sch.Bip. ex Baker., popularly known as guaco, is a Brazilian medicinal plant belonging to Asteraceae family and widely used in medicine to treat coughs and respiratory disorders. It presents bronchodilator and antiulcer activities among others. Coumarins, terpenes and organic acids are the main chemical constituents of this specie. In the literature no studies were found concerning the production of standardized dried extracts from this plant specie, therefore the aim of this study was the obtaining and the characterization of standardized dry extract of this plant specie. M. laevigata leaves were collected, dried and crushed, resulting in the plant drug. The hydroalcoholic extract was obtained by percolation of the drug plant and the extraction liquid used was ethanol 80% (v/v). After drying experiments were carried out in order to investigate the influences of the extract feed rate and the drying adjuvant ratio in the characteristics of the dried extracts obtained.-coumaric acid and coumarin were used as chemical markers and were quantified by High Performance Liquid Chromatography (HPLC) in all stages of the process. An analytical method was validated following the criteria proposed by the Agência Nacional de Vigilância Sanitária (ANVISA), proving to be selective, linear, precise, accurate, sensitive and robust. In the characterization of plant drug the volatile content obtained was 9.00 ± 1.75%, the coumarin content was 0.72 ± 0.02% and the acid -coumaric content was 0.13 ± 0.005%. The average particle size was 444.823 m and swelling index was 3.2 in ethanol 80%, 4.27 in ethanol 50% and 10.13 in water. The hydroalcoholic extract presented a density of 0.9256 ± 0.0006 g / mL, total solids content of 5.18 ± 0.21%, pH 6.1 ± 0.00, alcohol content of 56% and viscosity of 5.57 mPas. The drying yields ranged from 11.35 to 54.11%, and all dried products presented volatiles content and water activity below 5% and 0.5, respectively. The selected condition to be used to obtain standardized dried extracts of M. laevigata was that performed with a smaller proportion of colloidal silicon dioxide (15%) and increased extract feed rate (6mL/min), in which levels were obtained coumarin and -coumaric acid content of 1.83 ± 0.004% and 0.80 ± 0.012%, respectively. The dry extract obtained in these conditions showed spherical particles and their antiulcer activity in the model of indomethacin induced ulcers was demonstrated, suggesting a gastroprotective effect of this extract. Comparison of powder, hydroalcoholic and dry extract chromatographic (TLC and HPLC) show that the hydroalcoholic extraction was suitable for the extraction of coumarin and -coumaric acid and the drying process did not cause changes in the chemical profile of the extract in relation to these substances. Thus, the production of dried extracts by spray drying from the leaves of M. laevigata can be an interesting and promising alternative for obtaining such an intermediate product.
Mikania laevigata Sch.Bip. ex Baker., conhecida popularmente como guaco, é uma planta medicinal brasileira, pertencente à família Asteraceae, muito utilizada em medicamentos para tratar a tosse e distúrbios respiratórios. Apresenta atividades broncodilatadora, antiulcerogênica entre outras. Cumarinas, terpenos e ácidos orgânicos são os principais constituintes químicos desta espécie. Na literatura pesquisada não foram encontrados trabalhos abordando a produção de extratos secos padronizados de guaco, por isso o objetivo deste trabalho foi a obtenção e a caracterização do extrato seco padronizado desta espécie vegetal. As folhas de guaco foram coletadas, secas em estufa e trituradas, obtendo-se a droga vegetal. O extrato hidroalcoólico foi obtido através da percolação da droga vegetal utilizando como líquido extrator etanol 80%(v/v). Em seguida foram realizados diversos experimentos de secagem por spray drying com o intuito de investigar as influências da vazão de alimentação do extrato e da proporção de diferentes adjuvantes de secagem nas características dos extratos secos obtidos. A cumarina e o ácido -cumárico foram utilizados como marcadores químicos e foram quantificados por Cromatografia Líquida de Alta Eficiência (CLAE) em todas as etapas do processo. Foi validado um método analítico seguindo os critérios propostos pela Agência Nacional de Vigilância Sanitária (ANVISA), o qual foi seletivo, linear, preciso, exato, sensível e robusto. Na caracterização da droga vegetal o teor de voláteis obtido foi de 9,00 ± 1,75%, o teor de cumarina foi de 0,72 ± 0,02% e o teor de ácido -cumárico foi de 0,13 ± 0,005%. O tamanho médio de partículas foi de 444,823 μm e o índice de intumescência foi de 3,2 em etanol 80%, 4,27 em etanol 50% e 10,13 em água. O extrato hidroalcoólico apresentou densidade 0,9256 ± 0,0006 g/mL, teor de sólidos totais de 5,18 ± 0,21%, pH 6,1 ± 0,00, teor alcoólico de 56% e viscosidade de 5,57 mPas. Os rendimentos de secagem variaram de 11,35 a 54,11%, sendo que em todos os produtos secos, foram observados teores de voláteis e atividade de água abaixo de 5% e 0,5, respectivamente. A condição selecionada para ser empregada na obtenção de extratos secos padronizados de guaco foi aquela realizada com menor proporção de dióxido de silício coloidal (15%), maior vazão de alimentação do extrato (6mL/min), na qual obteve-se teores de cumarina e ácido cumárico de 1,83 ± 0,004 e 0,80 ± 0,012, respectivamente. O extrato seco obtido nestas condições apresentou partículas esféricas e a sua atividade antiulcerogênica no modelo de úlceras induzidas por indometacina foi demonstrada, sugerindo-se um efeito gastroprotetor. O perfil cromatográfico (CCD e CLAE) do pó, do extrato hidroalcoólico e do extrato seco demonstrou que a extração hidroalcoólica foi adequada para a extração de cumarina e ácido-cumárico e o processo de secagem não ocasionou alterações no perfil químico do extrato em relação a estas substâncias. Dessa forma, a produção de extratos secos por spray drying a partir das folhas de M. laevigata pode ser uma alternativa interessante e promissora para a obtenção desse produto intermediário.

Full textLos licores son bebidas hidroalcohólicas, especialmente de frutas y extractos de plantas; aromatizadas y endulzadas con azúcar o miel, destinados al consumo humano. Desde la antigüedad estas bebidas eran consideradas como espirituales y medicinales. Por otro lado, existen plantas que no han sido utilizadas aun en la industria de los alimentos, entre estas platas se encuentran algunos tipos de malezas cuyas cualidades van desde las aromáticas hasta las curativas. El objetivo de este trabajo es desarrollar un licor que sea agradable por los consumidores a partir del aprovechamiento de una maleza conocida como “guaco”; cuyos atributos aromáticos y olfativos lo vuelven diferente al resto de este tipo de plantas. Se desarrollaron tres licores, cada uno a diferentes concentraciones de alcohol; T1 al 10% de concentración alcohólica, T2 al 20% de concentración alcohólica y T3 al 30% de concentración alcohólica. Las características fisicoquímicas que se midieron en la elaboración de estos tratamientos son: Color, pH, Densidad, °Bx, °GL y vida de anaquel. La evaluación sensorial se aplicó a 100 personas dentro de la Facultad de Ciencias Agrícolas, mediante una prueba afectiva con escala hedónica de cero a cien. El tratamiento que tuvo mayor aceptación fue para el T2.

Resumo: Neste trabalho foi estudada a planta Mikania laevigata Sch. Bip, uma vez que é utilizada na medicina alternativa para fazer xaropes e chás devido as suas propriedades terapêuticas. Foram avaliados os efeitos sazonais e da composição do solvente extrator, bem como as suas interações na qualidade e no rendimento dos extratos brutos e das frações neutras, orgânicas, básicas, polares e fibras. O modelo estatístico de mistura do tipo Centróide-Simplex com quatro componentes, etanol, acetona, clorofórmio e diclorometano, foi empregado para a extração dos metabólitos secundários e os resultados indicaram que os efeitos sazonais são evidentes para o rendimento dos extratos brutos e todas as frações. Por outro lado, os efeitos dos solventes são importantes e significativos para o extrato bruto e frações, exceto a fração polar. Métodos estatísticos multivariados e univariados foram empregados aos dados gravimétricos e aqueles obtidos por cromatografia líquida de alta eficiência com detecção por arranjo de diodos (CLAE-DAD) e cromatografia líquida de ultra-eficiência acoplada à espectrometria de massas com ionização por electrospray (CLUE-IES-EM). As análises das frações orgânicas permitiram estudar as quantidades relativas da cumarina, a principal substância química de ação farmacológica encontrada na Mikania, e também dos ácidos melilótico e o-cumárico, sendo este último o precursor biossintético da cumarina. A existência e medição das abundâncias relativas do ácido melilótico na planta Mikania laevigata não foi relatada anteriormente. As concentrações dos ácidos melilótico e o-cumárico foram altamente correlacionadas durante todo o ano. As maiores concentrações da cumarina foi obtida no verão, enquanto que para os ácidos o-cumárico e melilótico a maior abundância foi na primavera. O efeito do solvente também se mostrou significativo. No verão, etanol extraiu a maior quantidade de cumarina na planta. As maiores quantidades dos ácidos o-cumárico e melilótico foram extraídas por misturas contendo os solventes etanol e acetona em suas composições nas estações primavera e inverno
Abstract: In this work the secondary metabolites of the Mikania laevigata Sch. Bip plant have been studied since they are used in alternative medicine for making syrups and teas with reputed therapeutic advantages. We have evaluated seasonal and solvent composition effects as well as their interactions for crude extract and organic, neutral, basic, polar and fiber fraction yields. The Simplex-Centroid mixture design for the ethanol, dichloromethane, chloroform and acetone solvents has been applied to the extraction of the secondary metabolites, and the results indicate that significant seasonal effects exist for the crude extract and all the fraction yields. On the other hand, the solvent effects are seen to be significant for the crude extract and all the fractions except the polar one. Both univariate and multivariate statistical methods were applied to the gravimetric data and those obtained by RP-HPLC-DAD and both positive and negative modes of UPLC-MS analyses. Analyses the organic fraction of the M. laevigata plant allowed determining the relative quantities of coumarin, the principal active pharmacological substance in Mikania, o-coumaric acid, the coumarin biosynthesis precursor, and melilotic acid for each solvent composition of samples harvested in the four different seasons. The existence and measurement of the relative abundances of melilotic acid in Mikania laevigata have not been reported previously. o-coumaric and melilotic acids concentrations were strongly correlated during the year. Highest coumarin concentrations were encountered in the summer whereas its o-coumaric acid precursor as well as melilotic acid were most abundant in the spring. Also the solvent effects are seen to be significant. In summer, ethanol extracted the highest amount of coumarin from the plant. Highest amounts of o-coumaric and melilotic acids were extracted by mixtures containing both ethanol and acetone in the winter and spring

Nativas da Mata Atlântica do Brasil, a Mikania laevigata Sch. Bip. ex Baker e Mikania glomerata Spreng., são comumente conhecidas como guaco e largamente utilizadas para afecções do sistema respiratório. A cumarina contribuiu para o efeito farmacológico juntamente com outras substâncias químicas nessas espécies. A composição química de uma planta é influenciada por vários fatores abióticos, a nutrição requer ênfase, pois a deficiência ou o excesso comprometem a produção de biomassa e o teor de metabólitos secundários. Diante disso, o trabalho teve como objetivo avaliar os efeitos dos níveis de N, P e K, provenientes da cama-de-aviário, na produtividade e teor de cumarina das duas espécies de guaco M. glomerata e M. laevigata. O estudo foi conduzido na Fazenda Experimental Lageado, da Faculdade de Ciências Agronômicas - UNESP, Campus de Botucatu-SP. O delineamento utilizado foi o inteiramente casualizado com cinco tratamentos e quatro repetições, os tratamentos consistiram em doses de NPK de formulação orgânica (T1= 0-0-0; T2 = 120-120-100; T3 = 240-240-200; T4=360-360-300; T5= 480-480-400 kg. ha-1). Ao final do experimento foram avaliadas: biomassa fresca e seca da parte aérea e raiz, altura de planta, área foliar, número de folhas, comprimento e volume da raiz, índice SPAD, teor de macro e micronutrientes das folhas do guaco, além do teor de cumarina. Os dados obtidos foram submetidos à análise de variância e para as variáveis que apresentaram diferenças significativas foi realizada análise de regressão, a correlação de Pearson foi utilizada para relacionar o teor de cumarina com os nutrientes foliares. Não foram observadas diferenças significativas para comprimento da raiz e teor de cumarina, que não apresentaram diferenças significativas para nenhuma das formulações estudadas em nenhuma das espécies. Houve ajuste quadrático para as variáveis, podendo assim calcular uma dose ideal para que se alcance o máximo de produção para Mikania laevigata e Mikania glomerata. Ao se correlacionar o teor de cumarina com os nutrientes foi verificada que a espécie M. laevigata correlacionou negativa e moderadamente com fósforo e cobre, enquanto não houve correlação significativa para a outra espécie estudada. Conclui-se que, a melhor formulação de NPK para M. laevigata e M. glomerata, é de 255,255 e 230 kg.ha-1 e 238,238 e 270 kg.ha-1, o que corresponde a 40 t.ha-1 de cama de frango. Essa dose permitirá maior produtividade sem ocorrer diminuição no teor de cumarina.
Native to the Atlantic forest of Brazil, and Mikania glomerata Spreng and Mikania laevigata Schultz. Bip. ex Baker, are commonly known as guaco, and widely used for respiratory system disorders. Coumarin contributed to pharmacological effect along with other chemicals in these species. The chemical composition of a plant is influenced by various abiotic factors, nutrition requires emphasis, because the deficiency or excess biomass production and undermine the content of secondary metabolites. Thus, the work aimed to evaluate the effects of the levels of N, P and K from the poultry litter, productivity and coumarin content of two species of guaco M. glomerata and M. laevigata. The study was conducted in Fazenda Experimental Lageado, da Faculdade de Ciências Agronômicas - UNESP, Campus de Botucatu-SP. The experimental design used was the completely randomized design with five treatments and four replications, treatments consisted of NPK formulations ((T1= 0-0-0; T2 = 120-120-100; T3 = 240-240-200; T4=360-360-300; T5= 480-480-400 kg. ha-1). At the end of the experiment were evaluated: fresh and dry biomass of shoot and root, plant height, leaf area, leaf number, length and volume of the root, SPAD index, content of macro and micro-nutrients from the leaves of guaco, besides the coumarin content. The data were submitted to analysis of variance and the variables that showed significant differences regression analysis was performed, the Pearson correlation was used to relate the coumarin content with foliar nutrients. There were no significant differences for root length and coumarin content, which did not present significant differences for any of the formulations studied in either species. There was a quadratic adjustment for the variables, so that an ideal dose could be calculated to reach maximum production for Mikania laevigata and Mikania glomerata. When correlating the content of coumarin with nutrients, it was verified that the species M. laevigata correlated negatively and moderately with phosphorus and copper, while there was no significant correlation for the other species studied. It is concluded that the best NPK formulation for M. laevigata and M. glomerata is 255,255 and 230 kg.ha-1 and 238,238 and 270 kg.ha-1, corresponding to 40 t.ha-1 of poultry litter. This dose will allow higher productivity without a decrease in coumarin content.
