Resumo: O Coriandrum sativum L. conhecido popularmente como coentro é citado como antidiabético, antiinflamatório, hipoglicemiante e antibacteriano. O gênero Candida faz parte da microbiota da cavidade oral e sob circunstâncias especiais produzem candidíase e infecções sistêmicas. O objetivo desse trabalho foi avaliar a atividade do óleo essencial (OE), extratos hexânico (EHE) e hidroalcoólico (EHA) de folhas de C. sativum frente as diferentes espécies de Candida e identificar seus principais constituintes. Para obtenção dos EHE e EHA foram utilizadas 10g das folhas secas e moídas, originando-se 0,43 g do EHE e 2,34 g do EHA, com rendimentos de 4,3% e 24,3%, respectivamente. O OE (2,06 g - rendimento 0,03%) foi obtido por hidrodestilação em sistema do tipo Clevenger a partir de 7500 g de folhas frescas, sendo fracionado em coluna seca e originando sete frações (FOE) com diferentes polaridades, as quais foram analisadas por CCD e CG-EM. Os constituintes majoritários identificados do OE foram álcoois e aldeídos de cadeia linear: 1- decanol (24,17%), 2E-decenol (18,05%) e 2Z-dodecenol (17,55%). Os OE, EHE e EHA foram testados frente as diferentes espécies de Candida: C. albicans CBS 562; C.krusei CBS 573; C. parapsilosis CBS 604; C. dubliniensis CBS 7987 e C. tropicalis CBS 94. As amostras do OE e extratos foram solubilizadas em água destilada e tween 1% para concentração em solução de 4 mg/mL, testando-se concentrações de 1000 Yg/mL a 15,6Yg/mL. O OE apresentou forte inibição frente as diferentes espécies de Candida com MICs de 125 a 500 Yg/mL, enquanto os EHE e EHA inibiram apenas C. parapsilosis com MIC de 250 Yg/mL. As frações 4, 5 e 6 do OE enriquecidas em álcoois apresentaram forte inibição e amplo espectro antimicrobiano, com MICs de 7 a 250 Yg/mL, evidenciando que esses compostos são responsáveis pela atividade antimicrobiana frente as diferentes espécies de Candida , enquanto as frações FOE 1 a 3 ricas em aldeídos, com MICs de 31 a 1000 Yg/mL, apresentaram atividade antimicrobiana moderada. Esses resultados demonstram o potencial uso de Coriandrum sativum no combate a leveduras do gênero Candida
Abstract: Coriandrum sativum L. (Umbelliferae / Apiaceae), known as coriander, is a popular cooking condiment in Brazil; it has been reported as an anti-inflammatory, anti-diabetic and anti-bacterial agent. Different Candida spp., which might lead to complications such as skin candidosis or even systemic infections, are commonly found in the oral microbiota. The aim of this study was to evaluate the activity of the essential oil (EO) and hexanic and hydroalcoholic extracts of C. sativum against different species of Candida, as well as to identify their main constituents. To obtain the hexanic (HEE) and hydroalcoholic extracts (HAE), 10 g of dried leaves of C. sativum was used to attain 0.43 g of HEE and 2.34 g of HAE, with yields of 4.3% and 24.3%, respectively. Its essential oil (2.06 g ¿ yield 0.03 %) was obtained by hydrodistillation using the Clevenger system where 7500 g of its fresh leaves and dry-column chromatography was used to fraction the oil into seven fractions with different polarities. These fractions were then analyzed by TLC and GC-MS. The main constituents identified in the essential oil were long-chain alcohols: 1-decanol (24.17 %); 2E-decenol (18.05 %); and 2Z-dodecenol (17,55 %) and aldehydes. The HEE, HAE, and EO were tested against C. albicans CBS 562, C. krusei CBS 573, C. parapsilosis CBS 604, C. dubliniensis CBS 7987, and C. Tropicalis CBS 94. Samples of EO, HEE and HAE were dissolved in distilled water with 1% tween to obtain a solution concentration of 4 mg/mL and 1000 µg/mL to 15.6 µg/mL of which was tested against Candida spp. The EO showed antibacterial activity against most species of Candida, with MICs ranging from 125 µg/mL to 500 µg/mL, while the extracts inhibited only C. parapsilosis with a MIC of 250 µg/mL. Alcohol-enriched fractions 4, 5 and 6 of EO showed strong inhibition and broad antimicrobial spectrum, with MICs ranging from 7 to 250 µg/mL, suggesting that alcohol might be responsible for the antimicrobial activity against the various species of Candida tested. While the fractions 1 to 3 rich in aldehydes, with MICs ranging from 31 to 1000 µg/mL, showed moderate antimicrobial activity against the species of Candida tested. Results showed potential antimicrobial activity of Coriandrum sativum against Candida spp (yeast infections)

Full textAs plantas medicinais são uma das mais importantes fontes de medicamentos para a indústria farmacêutica. Entre as plantas utilizadas na medicina popular no nordeste do Brasil, a Lippia gracilis Schauer (Verbenaceae) é uma das mais tradicionais e tem sido usada para diversos propósitos. Sendo assim, o presente trabalho teve por objetivo geral avaliar o potencial anticâncer do óleo essencial (OE) das folhas de L. gracilis em modelos experimentais in vitro e in vivo. O OE foi extraído por hidrodestilação e a análise química foi feita por CG/EM. Os efeitos citotóxicos do OE e dos seus componentes, timol, p-cimeno, γ-terpineno e mirceno, foram avaliados em células tumorais das linhagens HepG2, B16-F10 e K562, bem como em células não-tumorais (PBMCs). O efeito do OE na proliferação celular e na indução de apoptose foram investigados nas células HepG2. Além disso, camundongos transplantados com células do tumor Sarcoma 180 foram usados para confirmar sua eficácia in vivo. Os resultados mostraram que o OE apresentou o timol como composto químico majoritário e demonstrou promissora citotoxidade contra todas as células tumorais testadas. Por outro lado, os seus componentes investigados, apresentaram efeito citotóxico pouco potente. Além disso, o tratamento com o OE acarretou parada do ciclo celular das células HepG2 na fase G1, acompanhada por indução de fragmentação do DNA, sem afetar a integridade da membrana. Morfologia celular consistente com apoptose e uma notável ativação de caspase-3, também foram observadas, sugerindo indução de morte celular por apoptose dependente de caspase. O estudo da atividade antitumoral in vivo mostrou inibição do crescimento tumoral com taxas de 38,5% 41,9%. Assim, o OE apresentou o timol como principal constituinte e demonstrou significativa atividade antitumoral in vitro e in vivo. Os resultados obtidos sugerem que o OE das folhas de L. gracilis é um potencial recurso medicinal, que pode vir a ser empregado no tratamento do câncer.

Resumo: O gênero Hyptis Jacq. (Lamiaceae) compreende cerca de 350 espécies e exibe grande diversidade morfológica no Cerrado brasileiro. As espécies são aromáticas e frequentemente utilizadas para o tratamento de infecções gastrintestinais, cólicas, dor, doenças de pele, rinofaringite, congestão nasal e febre. Hyptis spicigera Lam., uma erva daninha nativa do Brasil e típica do Cerrado, é também conhecida como catirina, hortelã, fazendeiro, cheirosa, cheirosa-de-espiga ou buchinha-do-cerrado. É fortemente aromática e diferencia-se das demais espécies de Hyptis pela forma da sua inflorescência. Seu óleo essencial é utilizado para tratar dores musculares, pancadas, luxações e problemas digestivos. O objetivo deste trabalho, baseado no uso popular da espécie, foi avaliar o potencial antiulcerogênico do óleo essencial comercial de Hyptis spicigera (OEH), bem como seus possíveis mecanismos de ação envolvidos. A análise de cromatografia gasosa-espectrometria de massa (CG-EM) do OEH indicou a presença de três monoterpenos majoritários: ?-pineno (50,8%), cineol (20,3%) e ?-pineno (18,3%). Foram realizados diferentes modelos experimentais de úlcera gástrica; com base em suas respectivas especificações foram incluídos dois grupos controle, um positivo (lansoprazol, carbenoxolona ou cimetidina) e um negativo (veículo - Tween 80, 12%, 10 mL/Kg). Após cada experimento, ratos Unib: WH foram sacrificados, seus estômagos removidos e abertos na região de maior curvatura e fotografados para quantificação da área de lesão ulcerativa por meio do programa AVSoft. OEH, na dose de 100 mg/Kg (v.o.), apresentou atividade antiulcerogênica contra lesões gástricas induzidas por etanol absoluto (97%) e DAINE (84%). Para avaliar os mecanismos de ação envolvidos na atividade aniulcerogênica de OEH atividades antisecretória, citoprotetora e antioxidante foram analisadas. O modelo de úlcera gástrica induzida por ácido acético e análises de western blotting (COX-2 e EGF) foram também utilizados para avaliar a capacidade cicatrizante de OEH. Esse óleo essencial não interfere na secreção ácida na mucosa gástrica; além disso, sua gastroproteção não depende de NO nem de compostos com G-SH. A atividade gastroprotetora de OEH ocorre devido ao aumento na produção de muco (28%) induzido pelos níveis gástricos de PGE2. OEH demonstrou também potente capacidade de cicatrização, com 87% de redução da área de lesão ulcerativa, devido ao aumento na expressão de COX-2 (75%) e EGF (115%) na mucosa gástrica. Existem evidências de que ERO participam na etiologia de úlcera gástrica e muitos óleos essenciais foram recentemente qualificados como antioxidantes naturais. A capacidade do OEH de reduzir ou prevenir estresse oxidativo foi avaliada in vitro e in vivo, na mucosa gástrica de ratos Unib: WH submetidos à úlcera induzida por etanol absoluto. OEH apresentou atividade antioxidante, via transferência de H+, relacionado ao sequestro de radicais peroxil. Nenhum sinal de toxicidade foi observado nesse estudo, considerando os parâmetros analisados.
Abstract: Hyptis Jacq. (Lamiaceae), with almost 350 species, exhibits large morphological diversity in the Brazilian Cerrado region. Its species are quite aromatic and recommended in folk medicine for the treatment of many gastrointestinal infections, colic, pain, skin diseases, rynopharingites, nasal congestion and fever. Hyptis spicigera Lam., a native wild shrub of Brazil widely distributed throughout the Cerrado, is also known as "catirina", "hortelã", "fazendeiro", "cheirosa", "cheirosa de espiga" or "buchinha-do-cerrado". It is strongly aromatic and the difference related to other Hyptis concerns its inflorescence form. The essential oil extracted from this plant is employed to treat muscular pain, punch, luxation and gastric disorders. Based on the popular indications of this plant for the treatment of gastrointestinal disturbances, the present work aimed on evaluating the antiulcerogenic potential of the commercial essential oil of Hyptis spicigera (OEH), as well as its possible mechanisms of action. Gas chromatography-mass spectrometry (GC-MS) analysis of OEH indicated three monoterpenes as major compounds: alpha-pinene (50,8%), cineole (20,3%) and beta-pinene (18,3%). Based on their respective specifications, the groups under each experimental model included positive (lansoprazole, carbenoxolone, or cimetidine) and negative (vehicle-Tween 80 at 12%, 10mL/Kg) controls. After each experiment, Unib: WH rats were killed; the stomachs were opened along the greater curvature and scanned. So that, the ulcerative lesion area could be counted, aided by the AVSoft program. OEH, at the dose of 100 mg/Kg (p.o.), provided effective gastroprotection against lesions induced by absolute ethanol (97%) and NSAID (84%). To elucidate the mechanisms of action involved in the OEH antiulcerogenic activity, the antisecretory, citoprotective and antioxidant actions were evaluated. The acetic acid-induced gastric ulcer model and western blotting assay (COX-2 and EGF) were also used to evaluate the OEH healing capacity. OEH does not interfere with H+ secretion in gastric mucosa and its gastric protection does not depend on nitric oxide (NO) and sulfhydryl compounds (SH). The gastroprotective action of OEH occurs due to an increase in the gastric mucus production (28%) induced by PGE2 levels. Furthermore, OEH demonstrated a great healing capacity with 87% of reduction in the ulcerative lesion area. It accelerated the healing of acetic acid-induced gastric lesions due to an increase in COX-2 (75%) and EGF (115%) expression in gastric mucosa. There are evidences concerning the participation of ROS in the etiology of gastric ulcer and many essential oils were recently described as natural antioxidants. The role of the essential oil in reducing or preventing the oxidative stress was evaluated in vitro and in vivo, on Unib:WH rat gastric mucosa submitted to absolute ethanol-induced (p.o) gastric ulcer model. OEH presented antioxidant activity, by transferring ions H+, related to peroxil radical scavenging. No sign of toxicity was observed in this study, considering the analyzed parameters.

Full textThe species Lippia alba (erva cidreira) is widely used in folk medicine. The composition of essential oil varies quantitative and qualitative, leading to the classification of different chemotypes. A rich pharmacological potential is related to the wide variation in chemical composition of these oils, which arouses the interest of researchers in establishing scientific explanations for such activities. The objective of this study was to evaluate the antimicrobial and antioxidant activities of essential oils of chemotype I, II and III, leaves of L. alba, and to investigate their possible relationships with the chemical composition of their essential oils. The chemical characterization of constituents of essential oils was performed using GC-MS by determining the percentage of constituents present in the samples. The antimicrobial activity of oils was determined by agar diffusion, and MIC and CLM methods by microdilution broth culture and plated on agar, respectively. The antioxidant activity was assessed by measurement of TBARS and by determining the activity of removal of free radicals by DPPH. Essential oils from leaves of L. alba were recognized by the presence of its major constituents in chemotype I (citral-myrcene), chemotype II (citral-limonene) and chemotype III (carvone-limonene). The three essential oils showed activity against S. aureus, even resistant, and C. albicans. For Gram-negative bacteria, the three chemotypes present action on the A. lwoffi; the chemotypes II and III inhibited the growth of A. baumannii, and only the chemotype II was that acted on E. coli ATCC 10536. The lowest MIC obtained for CLM and essential oils of chemotypes I, II and III were 0,312 and 0,625mg/mL, 0,312 and 0,312mg/mL and 0,625 and 0,625mg/mL, respectively. The diffusion technique in agar served as a preliminary step in determining the antimicrobial activity and MIC determination by broth dilution accompanied by reading of optical densities of cultures showed absorbance values similar to the positive control group by a certain concentration and then increased indicating a higher microbial growth. Three chemotypes of OELA reduced lipid peroxidation induced in the hippocampus and brain of rats, but showed no scavenging activity of free radicals measured by the DPPH test. Thus, the results suggest that essential oils of chemotype I, II and III of L. alba, have excellent antimicrobial activity, especially on S. aureus and C. albicans, whereas the diffusion method is an excellent screening method, the dilution method, by visual inspection and reading of absorbance, in addition to determine the MIC, the CLM and evaluate the kinetics of inhibition of microbial growth, the antioxidant potential shown OELA by the hippocampus and cortex of rats makes these products a potential pharmacological tool in the treatment of neurodegenerative diseases, however, for that additional studies are needed, and that differences in the composition of the oil is a factor to be considered important in studies pharmacological.
A espÃcie Lippia alba (erva-cidreira) à muito usada na medicina popular. A composiÃÃo de seu Ãleo essencial apresenta variaÃÃes quantitativas e qualitativas, levando à classificaÃÃo de diferentes quimiotipos. Um rico potencial farmacolÃgico està relacionado à ampla variaÃÃo na composiÃÃo quÃmica desses Ãleos, o que desperta o interesse de pesquisadores em estabelecer explicaÃÃes cientÃficas para tais atividades. O objetivo do trabalho foi avaliar as atividades antimicrobiana e antioxidante dos Ãleos essenciais dos quimiotipo I, II e III, de folhas, de L. alba, bem como investigar suas possÃveis relaÃÃes com a composiÃÃo quÃmica de seus Ãleos essenciais. A caracterizaÃÃo quÃmica dos constituintes dos Ãleos essenciais foi realizada utilizando a CG-MS, determinando-se a porcentagem dos constituintes presentes nas amostras. O potencial antimicrobiano dos Ãleos foi determinado pelo mÃtodo de difusÃo em Ãgar, e as CIM e CLM pelos mÃtodos da microdiluiÃÃo em caldo de cultura e do plaqueamento em Ãgar, respectivamente. A atividade antioxidante foi avaliada pela dosagem de TBARS e pela determinaÃÃo da atividade de remoÃÃo de radicais livres pelo DPPH. Os Ãleos essenciais das folhas de L. alba foram reconhecidos pela presenÃa de seus constituintes majoritÃrios em quimiotipo I (citral-mirceno); quimiotipo II (citral-limoneno) e quimiotipo III (carvona-limoneno). Os trÃs Ãleos essenciais apresentaram atividade sobre S. aureus, mesmo as multirresistentes, e C. albicans. Para as bactÃrias Gram-negativas, os trÃs quimiotipos apresentaram aÃÃo sobre o A. lwoffi; os quimiotipos II e III inibiram o crescimento do A. baumannii; e apenas o quimiotipo II foi que teve aÃÃo sobre E. coli ATCC 10536. As mais baixas CIM e CLM obtidas para os Ãleos essenciais dos quimiotipos I, II e III, foram de 0,312 e 0,625mg/mL, 0,312 e 0,312mg/mL e 0,625 e 0,625mg/mL, respectivamente. A tÃcnica de difusÃo em Ãgar serviu como uma etapa preliminar na determinaÃÃo do potencial antimicrobiano e a determinaÃÃo da CIM por diluiÃÃo em caldo acompanhada de leitura das densidades Ãticas das culturas, mostrou valores de absorbÃncias semelhantes ao grupo controle positivo atà uma determinada concentraÃÃo e entÃo aumentaram, indicando um maior crescimento microbiano. Os trÃs quimiotipos do OELA reduziram a peroxidaÃÃo lipÃdica induzida no hipocampo e cÃrebro de ratos, contudo nÃo apresentaram atividade seqÃestradora de radicais livres mensuradas atravÃs do teste do DPPH. Assim, os resultados sugerem que os Ãleos essenciais dos quimiotipo I, II e III de L. alba, possuem excelente atividade antimicrobiana, principalmente sobre S.aureus e C. albicans; que o mÃtodo de difusÃo à um excelente mÃtodo de triagem; que o mÃtodo da diluiÃÃo, por inspeÃÃo visual e leitura de absorbÃncia, permite determinar alem da CIM, a CLM e avaliar a cinÃtica de inibiÃÃo de crescimento microbiano; o potencial antioxidante mostrado pelo OELA no hipocampo e cÃrtex de rato, torna esses produtos uma ferramenta farmacolÃgica em potencial no tratamento de doenÃas neurodegenerativas, contudo, para isso estudos adicionais sÃo necessÃrios; e que as diferenÃas na composiÃÃo do Ãleo à um fator que deve ser considerado importante nos estudos farmacolÃgicos.

Full textThe planted eucalyptus forests have been very important to supply material for a variety of purposes, mostly from wood. The genus is also known to have an important range of potential species to source essential oils from the leaves. In Brazil, however, essential oil production has been restricted to a few species. Hence, it is important to conduct studies that may extend the number of new materials to obtain essential oil. In order to meet such demand, this study was proposed, which sought to assess new materials, including not only the leaves but also the flowers of trees of different species and clones of eucalyptus, for the production of essential oils. Essential oil extractions were performed by steam distillation, to determine their yield, and chromatographic analysis to identify their chemical components. The results indicated: a) the highest yields in essential oils of leaves were observed for E. staigeriana (1,599%) and C. citriodora (1,262%), and the lowest for C. ptychocarpa (0,021%); b) E. exserta (0,613%) and E. resinifera (0,587%) had potential for use of their essential oils, due to their high yields and the important presence of 1,8 cineole; c) the highest yields in essential oils of flowers were observed for GFMO 03 (0,518%) and the lowest for E. exserta (0,109%); d) the clone GFMO 03 showed flowers with highest yield in essential oil than the leaves, which may be related to genetic improvement done in order to favor their flowering characteristics; e) the substances in essential oils of leaves may assist the identification and differentiation of species; f) the essential oils of flowers had 6 substances that were not found in the leaves; g) many of the substances in essential oils of flowers are present in propolis, suggesting that they have connection with pollinators activities linked to beekeeping; h) the high concentration of substances of interest in essential oils of eucalyptus demonstrate its importance as suppliers of raw materials for industry; i) the species were grouped by the chemical composition in essential oils of their leaves, which resulted in 4 groups and 6 subgroups, which may be related to the area of natural occurrence of the studied species; j) GFMO 03 and GFMO 10 are, respectively, in the same group of E. grandis and E. tereticornis, species which compound the genetic material of the clones, indicating that the essential oil features are probably preserved even after hybridization.

A espécie Myrciaria floribunda (H.West ex Willd.) O. Berg., Myrtaceae, popularmente conhecida como camboim-amarelo, foi coletada no Parque Nacional da Restinga de Jurubatiba (RJ, Brasil). Esta espécie é rica em estruturas secretoras de óleo essencial. Neste trabalho, é descrita a análise da composição química dos óleos essenciais de folhas, caules e flores. O monoterpeno 1,8 cineol apresenta-se como componente majoritário nos óleos de folhas (38,4%) e flores (22,8%). No óleo de caules a substância majoritária foi o acetato de farnesila (19,9%). Além das substâncias já descritas para o óleo essencial de folhas desta espécie, foram identificadas pela primeira vez: α-pineno (0,4%), mirceno (0,7%), (Z)-β-ocimeno (0,8%), γ-terpineno (0,8%), acetato de geranilo (1,5%), γ-himachaleno (7,0%), valenceno (1,8%), δ-amorpheno (4,0%), zonareno (4,6%), selina-3.7(11)-dieno (3,8%), neo-intermedeol (0,8 %) e (2E, 6Z)-farnesol (1,4%). As análises dos óleos essenciais de caules e flores ainda não haviam sido descritas para esta espécie. Também foram isolados e identificados pela primeira vez na espécie o triterpeno ácido betulínico e o flavonoide miricetina 3-O-β-galactosídeo da fração acetato de etila de folhas. O óleo essencial de folhas foi avaliado quanto as atividades: anticolinesterásica, antimicrobiana e inseticida. Os óleos de folhas, flores e caules foram avaliados quanto a atividade anticolinesterásica, mostrando um IC50 de 1583 e 681 μg/mL para flores e folhas, respectivamente. O óleo de caules não apresentou atividade. O teste de susceptibilidade antimicrobiana do óleo essencial das folhas utilizando cepas de Staphylococcus aureus ATCC 29213, apresentou um CMI de 250 μg/mL. A atividade inseticida do óleo essencial das folhas foi avaliada frente aos fitófagos Oncopeltus fasciatus e Dysdercus peruvianus e os óleos essenciais das folhas e flores foram avaliados frente ao percevejo hematófago da espécie Rhodnius prolixus. Os tratamentos dos insetos com os óleos essenciais de M. floribunda induziram mortalidade, atraso no desenvolvimento e inibição de muda. Para avaliar a atividade hipoglicemiante e integridade do fêmur em ratos machos, foi utilizado o extrato aquoso das folhas de M. floribunda a uma concentração de 5 % (p/v), onde foi possível verificar ao final dos 42 dias de tratamento uma diferença significativa na glicemia e resultados similares para o fêmur. O grupo tratado apresentou resultados significativamente aumentados de colesterol, proteína total, fósforo, magnésio e aspartato aminotransferase, massa de fígado menor e massa dos rins maiores quando comparados com o grupo controle.

This species is rich in secretory structures essential oil. This work describes the analysis of the chemical composition of the essential oil of leaves, stems and flowers in that the monoterpene 1.8-cineole present as the major component in the oil leaves and flowers corresponding 38.4% 22.8%, respectively. Already at oil from stems the substance majority was farnesyl acetate (19.9%). In addition to the substances already described for the essential oil from leaves of the species were first identified the following substances : α-pinene (0.4%), myrcene (0.7%), (Z)-β-ocimene (0.8%), γ-terpinene (0.8%), geranyl acetate (1.5%), γ-himachalene (7.0%), valencene (1.8%), δ-amorphene (4.0%), zonarene (4.6%), 3.7-selina (11) -diene (3.8%), neo-intermedeol (0.8%) and (2E, 6Z)-farnesol (1.4%). The analysis of essential oils from stems and flowers had not yet been described. Were also isolated and identified for the first time in the kind triterpene betulinic acid and flavonoid myricetin 3-O-β-galactoside of ethyl acetate fraction of leaves. The essential oil from leaves was evaluated for activities: acetylcholinesterase, antimicrobial and insecticidal. The oils from leaves, flowers and stems were evaluated for anticholinesterase activity, showing an IC50 of 1583 and 681 mg/mL for flowers and leaves, respectively, and stems showed no activity. The antimicrobial susceptibility testing essential oil from leaves using Staphylococcus aureus ATCC 29213, filed an IMC 250 μg/mL. Insecticidal activity of the essential oil from the leaves was evaluated against phytophagous Oncopeltus fasciatus and Dysdercus peruvianus, and the essential oil from the leaves and flowers were evaluated against the Rhodnius prolixus. All treatments of insects with essential oils of M. floribunda induced mortality, developmental delay and inhibition of molting. To evaluate the hypoglycemic activity and femur health in male rats, were evaluated with the aqueous extract of leaves of M. floribunda at a concentration of 5%, which was verified at the end of the 42 days of treatment the infusion decreased the glycemia e maintenance results similar to the femur. Treated group apresented results significantly increased to cholesterol, total protein, phosphorus, magnesium and aspartate aminotransferase, mass minor liver and kidney mass was increased compared with the control group

Os óleos essenciais são misturas naturais, complexas de substâncias voláteis que possuem aroma intenso, são líquidos de aspecto oleoso a temperatura ambiente, mas se volatilizam em exposição ao ar em temperaturas específicas. Considerados como os agentes antimicrobianos mais importantes presentes nas plantas, os óleos essenciais possuem também propriedades antioxidante, anti-inflamatória, inseticida, entre outras. O óleo essencial de laranja constitui-se de compostos aromatizantes quimicamente instáveis. Estes se degradam facilmente na presença de luz, ar e umidade. Pensando nisso, este trabalho estudou a microencapsulação do óleo essencial de laranja doce (Citrus sinensis v. dulcis) utilizando maltodextrina e gelatina como encapsulantes de baixo custo, como alternativa para aumento da estabilidade, além de incentivar a agregação de valor às cascas, rejeito do qual o óleo essencial é obtido, com vistas à preservação ambiental. O estudo foi conduzido no Laboratório de Nutrição Animal, Centro de Saúde e Tecnologia Rural (CSTR), Universidade Federal de Campina Grande – UFCG, Campus de Patos – PB. Três formulações microencapsuladas foram desenvolvidas, em que os sistemas microencapsulados foram preparados com teor fixo de óleo essencial de laranja (10% m/m), variando-se a proporção de encapsulantes das formulações, em que a primeira incluiu apenas maltodextrina e as demais englobaram proporção de maltrodextrina e gelatina de 2:1 e 1:1, respectivamente. As formulações foram obtidas por emulsificação/liofilização. O estudo resultou em um pedido de patente (BR 10 2017 004722 9), depositado junto ao Instituto Nacional de Propriedade Industrial. O produto final obtido possui forte caráter de inovação tecnológica, além de maior segurança no manuseio, maior vida de prateleira e, portanto, o máximo de manutenção de integridade, somando-se, ainda, a possibilidade de inserção de um produto de alto valor agregado no mercado nacional, em que, dentre inúmeros setores, um dos grandes favorecidos é a indústria alimentícia, incluindo, ainda, o fortalecimento da interação entre Universidade e Indústria e também a preservação do meio ambiente.
Essential oils are natural, complex mixtures of volatile substances that have intense aroma; they are liquids of oily appearance at room temperature, but they volatilize in exposure to air at specific temperatures. Considered as the most important antimicrobial agents present in plants, essential oils also have antioxidant, anti-inflammatory, insecticidal properties, among others. Orange essential oil consists of chemically unstable flavoring compounds, which easily degrade in the presence of light, air and moisture. With this in mind, this work studied the microencapsulation of sweet orange essential oil (Citrus sinensis v. dulcis) using maltodextrin and gelatin as low cost encapsulants, as an alternative to increase stability, as well as to encourage the aggregation of value to the peels, from which the essential oil is obtained, aiming at environmental preservation. The study was conducted at the Animal Nutrition Laboratory, Center for Health and Rural Technology (CSTR), Federal University of Campina Grande - UFCG, Campus Patos - PB. Three microencapsulated formulations were developed in which the microencapsulated systems were prepared with fixed content of orange essential oil (10% m/m), varying the ratio of encapsulants of the formulations, in which the former included only maltodextrin and the others included proportion of maltodextrin and gelatin of 2: 1 and 1: 1, respectively. The formulations were obtained by emulsification / lyophilization. The study resulted in a patent application (BR 10 2017 004722 9), deposited with the National Institute of Industrial Property. The final product obtained has strong potential for technological innovation, as well as greater handling safety, longer shelf life and, therefore, the maximum integrity maintenance, also adding the possibility of insertion of a high - value product in the national market, where, among many sectors, one of the big beneficiaries is the food industry, including the strengthening of the interaction between University and Industry and also the preservation of the environment.
