Abstract:
Angiogenesis is a strictly controlled process defined as the formation of new blood vessels essential for certain physiologic and pathologic conditions where the latter includes tumor growth, development, and metastasis. Thus, inhibiting angiogenesis along with other anticancer strategies such as chemotherapy seems to be invaluable for reaching an optimal outcome in cancer patients. It has been shown that some natural plant-derived compounds are capable of preventing the formation of these new blood vessels in the tumor and also inhibit the proliferation and growth of the cancer cells. In this review, we intend to introduce plants with anti-angiogenic properties and discuss their related features.

Abstract:
In the history of humanity, great ancestors of Indian sub-continent used plants that possessed unique medicinal properties. They identified the plants from jungles and derived crude drugs out of them for treating infectious diseases. This treatment process was a tradition. In the recent century, this plant-based drug extraction, processing and refining began scientifically by pharmaceutical industries. In this new era, plants with medicinal features are being used in curing broad spectrum of diseases. Lannea Coromandelica (L.C.) is a medicinal plant that belongs to this category. Tribals extensively used it in treating various infectious diseases and common injuries. There have been very few studies on the leaves, barks, flowers, gums and mucilage of this tree. But no preliminary phytochemical composition of L.C. stem has been studied. Therefore, the current work focusses on the screening of the phytochemical profile of the stem of L.C. by the sequential ethanolic extract. Stems of L.C. were procured from Mettur, Tamil Nadu. Thirteen different components were qualitatively analyzed using standard procedures from 100g of L.C. stem extract. In this study, seven components were identified, and their percentage was estimated. Using GC-MS, 50 components were identified of which Pentadecanoic acid, 14-methyl-methyl ester (1.0%) was the major component. The presence of these components in L.C. stem extract can be used in the treatment of different ailments through their antioxidant, anti-arthritic, anti-diabetic, antiinflammatory and antimicrobial activities.

Abstract:
The main source of available forms of heavy metals (toxic metals) for the plant kingdom is anthropogenic, resulting from diverse activities such as metallurgic processing of ore, cement plants, uncontrolled discharge of sewage sludge, burning of fossil fuels and waste incineration plants, and leaded petrol. Agricultural chemicals (e.g. phosphate fertilizers containing cadmium) may also contribute to the contamination of cultivated plants. The main threats to human health from toxic metals are associated with exposure to lead, cadmium, mercury (organic forms, especially methylmercury) and arsenic (mineral form only), which have no known vital or beneficial effect on living organisms. As their toxicity often takes years to manifest and may go unsuspected, their toxicological risk is defined on the basis of the so-called Provisional Tolerable Weekly Intake (PTWI) values. Beside anthropogenic causes, the main factors that may lead to high levels of toxic metals in medicinal plants are their availability in the soil with soil pH as the most important parameter for uptake by the plant. Indeed, genetic features of certain plant species show a tendency to accumulate certain trace elements, especially cadmium (“cadmium collector”). A very recent revision draft of the monograph “Herbal drugs” (Ph. Eur., 1433) includes acceptance criteria for lead, cadmium and mercury. This proposal is discussed in detail, based on literature data dealing with terrestrial plants and seaweed. Additionally, the need for inclusion of tests for inorganic impurities in quality control specification is examined, based on a risk assessment. As the daily intake of food supplements is very similar to the one of herbal remedies, it would be advisable to take into account the same acceptance criteria. The specific situation has also been considered of exotic herbal remedies, particularly those of Asian origin, which have been repeatedly reported to contain toxic levels of heavy metals and/or arsenic resulting in heavy metal poisoning.

Abstract:
The present study was aimed at a comparative study of the phytoconstituents, antioxidant and antimicrobial properties of four medicinal plants, Ficus capensis, Aristolochia ringens, Albizia zygia and Lannea welwitschii. The leaf of F. capensis and stem bark of A. ringens, A. zygia and L. welwitschii were extracted using methanol. Phytochemical analysis was done spectrophotometrically. Three in vitro antioxidant tests-hydrogen peroxide (H2O2), nitric oxide (NO) and 2, 2-diphenyl-1-picrylhydroxyl (DPPH) scavenging models were employed. Antimicrobial test was done by agar diffusion method against E. coli, Staphylococcus aureus, Klebsiela pneumonia, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Candida albicans and Aspergittus spp. Phytochemical analysis revealed that the most abundant phytoconstituents were flavonoids (F. capensis and A. zygia), reducing sugar, terpenoids, alkaloids and tannins. In the antioxidant models, A. zygia was found to produce the least IC50 in two of the models (NO and DPPH). Results of the antimicrobial tests showed that A. zygia showed a broader spectrum of activity than other plants. This study has shown that these plants possess antioxidant and antimicrobial activities which further justify their usage in traditional medicines. A. zygia featured prominently in these activities. Also flavonoids could be responsible for the bioactivities of these plants.Dhaka Univ. J. Pharm. Sci. 16(2): 147-157, 2017 (December)

Abstract:
Plants living in different ecological habitats can show significant variability in their histological and phytochemical characters. The main histological features of various populations of three medicinal plants from the Boraginaceae family were studied. Stems, petioles and leaves were investigated by light microscopy in vertical and transverse sections. The outline of the epidermal cells, as well as the shape and cell number of trichomes was studied in leaf surface casts. Differences were measured among the populations of Echium vulgare in the width and height of epidermis cells in the stem, petiole and leaf, as well as in the size of palisade cells in the leaves. Among the populations of Pulmonaria officinalis significant differences were found in the length of trichomes and in the slightly or strongly wavy outline of epidermal radial cell walls. Populations of Symphytum officinale showed variance in the height of epidermal cells in leaves and stems, length of palisade cells and number of intercellular spaces in leaves, and the size of the central cavity in the stem. Boraginaceae bristles were found to be longer in plants in windy/shady habitats as opposed to sunny habitats, both in the leaves and stems of P. officinalis and S. officinale, which might be connected to varying levels of exposure to wind. Longer epidermal cells were detected in the leaves and stems of both E. vulgare and S. officinale plants living in shady habitats, compared with shorter cells in sunny habitats. Leaf mesophyll cells were shorter in shady habitats as opposed to longer cells in sunny habitats, both in E. vulgare and S. officinale. This combination of histological characters may contribute to the plant's adaptation to various amounts of sunshine. The reported data prove the polymorphism of the studied taxa, as well as their ability to adapt to various ecological circumstances.

Abstract:
Honey is a honey-bee product obtained mainly by the enzymatic processing of nectar from a variety of plants, which leads to the wide range of colours and flavours available on the market. These organoleptic and nutritional features are influenced by the chemical composition, which in turn depends on the botanical origin. Bioactive compounds account for honey beneficial activity in medical applications, which explains the extensive use of honey in ethno-pharmacology since antiquity, from cough remedies to dermatological treatments. Wound healing is one of the main therapeutic uses of honey, and various design options in pharmaceutical technology such as smart delivery systems and advanced dressings are currently being developed to potentiate honey’s valuable properties for better performance and improved final outcome. In this review, we will focus on the latest research that discloses crucial factors in determining what properties are most beneficial when considering honey as a medicinal product. We will present the most recent updates on the possible mechanisms responsible for the exceptional effects of this ageless therapeutical remedy on skin repair. Furthermore, the state-of-the-art in application techniques (incorporation into scaffolds as an alternative to direct administration) used to enhance honey-mediated wound-healing properties are explored.

Abstract:
Although acetylenes are common as components of terrestrial plants, it is only within the last 30 years that biologically active polyacetylenes having unusual structural features have been reported from aquatic organisms: cyanobacteria, algae, fungi, invertebrates, and other sources. Naturally occurring aquatic acetylenes are of particular interest since many of them display important biological activities and possess antitumor, antibacterial, antimicrobial, antifouling, antifungal, pesticidal, phototoxic, HIV inhibitory, and immuno-suppressive properties. There is no doubt that they are of great interest, especially for the medicinal and/or pharmaceutical industries. This review presents structures and describes cytotoxic and anticancer activities of more than 230 acetylenic metabolites isolated from aquatic organisms. With the computer program PASS some additional biological activities are also predicted, which point toward possible new applications of these compounds. This review emphasizes the role of aquatic acetylenic compounds as an important source of leads for drug discovery.

Abstract:
Nanoparticles possess unique features due to their small size and can be composed of different surface chemistries. Carbon quantum dots possess several unique physico-chemical and antibacterial activities. This review provides an overview of different methods to prepare carbon quantum dots from different carbon sources in order to provide guidelines for choosing methods and carbon sources that yield carbon quantum dots with optimal antibacterial efficacy. Antibacterial activities of carbon quantum dots predominantly involve cell wall damage and disruption of the matrix of infectious biofilms through reactive oxygen species (ROS) generation to cause dispersal of infecting pathogens that enhance their susceptibility to antibiotics. Quaternized carbon quantum dots from organic carbon sources have been found to be equally efficacious for controlling wound infection and pneumonia in rodents as antibiotics. Carbon quantum dots derived through heating of natural carbon sources can inherit properties that resemble those of the carbon sources they are derived from. This makes antibiotics, medicinal herbs and plants or probiotic bacteria ideal sources for the synthesis of antibacterial carbon quantum dots. Importantly, carbon quantum dots have been suggested to yield a lower chance of inducing bacterial resistance than antibiotics, making carbon quantum dots attractive for large scale clinical use.

Abstract:
Background:: Synthetic compounds with pharmaceutical applications in brain disorders are daily designed and synthesized, with well first effects but also seldom severe side effects. This imposes the search for alternative therapies based on the pharmaceutical potentials of natural compounds. The natural compounds isolated from various plants and arthropods venom are well known for their antimicrobial (antibacterial, antiviral) and antiinflammatory activities, but more studies are needed for a better understanding of their structural and pharmacological features with new therapeutic applications. Objectives:: Here we present some structural and pharmaceutical features of natural compounds isolated from plants and arthropods venom relevant for their efficiency and potency in brain disorders. We present the polytherapeutic effects of natural compounds belonging to terpenes (limonene), monoterpenoids (1,8-cineole) and stilbenes (resveratrol), as well as natural peptides (apamin, mastoparan and melittin). Methods:: Various experimental and in silico methods are presented with special attention on bioinformatics (natural compounds database, artificial neural network) and cheminformatics (QSAR, drug design, computational mutagenesis, molecular docking). Results:: In the present paper we reviewed: (i) recent studies regarding the pharmacological potential of natural compounds in the brain; (ii) the most useful databases containing molecular and functional features of natural compounds; and (iii) the most important molecular descriptors of natural compounds in comparison with a few synthetic compounds. Conclusion:: Our paper indicates that natural compounds are a real alternative for nervous system therapy and represents a helpful tool for the future papers focused on the study of the natural compounds.

Abstract:
Campomanesia xanthocarpa Berg, espécie pertencente à família Myrtaceae, é conhecida popularmente como gabiroba. Diversas propriedades terapêuticas são atribuídas às espécies de Campomanesia, tais como, combate à disenteria, febre, cistites e uretrites. O presente trabalho objetiva contribuir para elaboração de monografia da espécie, através do estudo químico e farmacológico do extrato hidroalcoólico liofilizado e da droga vegetal constituída de folhas. Os caracteres farmacobotânicos da droga vegetal são apresentados com o intuito de auxiliar a diagnose. Dentre as principais características macroscópicas das folhas desidratadas podem ser citadas: ondulação nas bordas; pontos translúcidos na lâmina, tipo de venação, forma da lâmina e dos pecíolos, e odor aromático. As características anatômicas que se destacaram são: mesofilo dorsiventral; grandes idioblastos contendo cristal prismático na região paliçádica; predominância de estômatos anomocíticos nas folhas hipoestomáticas; cavidades secretoras globosas, associadas a ambas as superfícies, recobertas por células dispostas aos pares em que a parede comissural mostra-se reta, sinuosa ou de \"zig-zag\"; feixe vascular bicolateral e sistema disposto em arco aberto; cristais prismáticos na região floemática. Fotomicrografias ilustraram o trabalho. A triagem fitoquímica da droga vegetal e do extrato liofilizado (EHA) indicou a presença de flavonóides, taninos, saponinas e óleo essencial. O teor de óleo essencial nas folhas frescas, foi de 0,11 %. Linalol (29%) e globulol (20%) foram identificados como os principais componentes do óleo. O teor de taninos na droga foi de 2,86 % e no extrato EHA, de 8,49 %. O teor de saponinas na droga foi de 6,27 % e no extrato EHA de 16%. O extrato apresentou elevada atividade antioxidante no modelo de medida de produção de malonildialdeído, com Q1/2 =0,2891 µg/mL. No ensaio da inibição da lipoperoxidação, induzida por sulfato de cobre, o extrato EHA reduziu significativamente o tempo de indução (\"Lag-time\") e o tempo de terminação (\"Peak-time\") da oxidabilidade de lipoproteínas de baixa densidade (LDL). O extrato EHA apresentou atividade antiúlcera no modelo de indução aguda por ácido clorídrico em etanol, com percentual de proteção de 62%. O extrato EHA apresentou atividade antimicrobiana com: CMI >1.000 e <500 µg/mL em relação a Staphylococcus aureus; CMI <500 e >100 µg/mL para Salmonella cholerasuis e CMI <1.000 e >500 µg/mL em relação a Candida albicans. O extrato EHA mostrou atividade citotóxica no ensaio da letalidade de artêmias, com DL50 de 0,503 mg/mL. O extrato EHA não apresentou toxicidade no ensaio de toxicidade aguda, na dose de 5g/kg de peso do animal, por via oral.
Campomanesia xanthocarpa Berg, a species that belongs to the Myrtaceae family, is popularly known as gabiroba. Several therapeutic properties are attributed to the various Campomanesia species, such as treating diarrhea, fever, cystitis and urethritis. This project aims at contributing through a chemical and pharmacological study of lyophilized hydrated alcohol extract and the vegetable drug made from leaves. The pharmacological and botanical features of the vegetable drug are indicated in order to help with the diagnosis. Main macroscopic features of the dehydrated leaves include: wavy edges, translucent blade spots, venation type, blade and leafstalk forms and scent. The main anatomical features are: dorsiventral mesophyll; large idoblasts containing prismatic crystal in the palisade parenchyma; predominance of anomocytic stomata in the hypostomatic leaves, globose segregating cavity associated to both surfaces, covered by cells organized in pairs where the commissure wall appears straight, sinuous, or in zigzag; bicollateral vascular bundle and system organized in an open arch, prismatic crystals in the phloem region. Photomicographs illustrate the study. The phytochemical screening of the vegetable drug and the lyophilized extract (EHA) indicated the presence of essential oil, flavonoids, tannins and saponins. The essential oil content in the fresh leaves was 0.11 %. Linalol (29%) and globulol (20%) were identified as the main oil components. Tannin content was 2.86% in the drug and 8.49% in the EHA extract. The saponin content was 6.27% in the drug and 16% in the EHA extract. The extract displayed a high antioxidant activity in the model of malonyl dialdehyde production measure with Q1/2 = 0,2891 µg/mL. In the copper sulfate-induced lipoperoxydation inhibition assay the EHA extract significantly reduced Lag-time and Peak-time for low-density lipoprotein (LDL) oxidability. The EHA extract displayed antiulceration activity in the acute induction model by hydrochloric acid in ethanol, with a 62% protection percentage. The EHA extract displayed antibacterial activity with: CMI >1,000 and <500 µg/mL relative to Staphylococcus aureus; CMI <500 and >100 µg/mL for Salmonella cholerasuis and CMI <1.000 and >500 µg/mL regarding Candida albicans. The EHA extract displayed cytotoxic activity in the artemias lethality trial, with DL50 of 0,503 mg/mL. The EHA extract displayed no toxicity in the acute toxicity trial in the 5g/kilo oral dosage per animal body weight.

Abstract:
This thesis describes phytochemical and biological/pharmacological studies on six medicinal plants. Plant materials were extracted by ethanol, tested for their biological activity and then subjected to "bioassay-guided fractionation" to yield active and inactive compounds. The compounds were identified by standard physico-chemical techniques including UV, IR, NMR and ElMS. The crude ethanol extract of the leaves of Premna shcimperi was found to be antibacterial against gram positive bacteria (Staphylococcus aureus and Bacillus subtilis). An antibacterial bioassay-guided fractionation of the extract resuited in the isolation of the active principle, (5R,8R,9S,10R)-12-oxo-ent-3,13(16)- clerodien-15-oic acid (SHM-l). This novel compound was bactericidal against S. aureus and B. subtilis at concentrations of 25 and 50 µg ml⁻¹. Studies on the structural-activity relationship of SHM-l showed that the α,β unsaturated moiety played a major role in its antibacterial activity. Investigation of the inactive fractions of P. schimperi extract afforded three flavonoid aglycones: luteolin, quercetin and kaempferidej three flavonoid glycosides: luteolin-4" -,β-D-glucoside, quercetin-3-,β-D-galactoside and quercetin-α-L-arabinopyranoside and five cinnamate and benzoate derivatives. The ethanol extract of the leaves of Premna oligotricha was also found to be antibacterial against a range of gram-positive bacteria. A bioassay-directed isolation afforded three novel active principles, two diterpenes: 16-hydroxy-clerod- 3,13(14}-diene-15,16-olide (SHM-3) and ent-12-oxolabda-8,13(16}-dien-15-oic acid (SHM-S) and a sesquiterpene, 7-α, hydroxy-2-oxo-6,11-cyclofarnes-3(15)-ene (SHM-19). While the activity of SHM-5 and SHM-19 was marginal that of SHM-3 was good, almost comparable with streptomycin. The antimicrobially inactive fractions of P. oligotricha extract yielded a novel diterpene, ent-8,β12α-epidioxy- 12,β-hydroxlabda-9(11), 13-dien-15-oic acid γ lactone and two novel flavonoids: 3,5,5'-trihydroxy-6,7 ,3' ,4'-tetramethoxyflavone and 3,5,7 ,5'-tetrahydroxy-6,3',4'- trimethoxyflavone. Investigation of the leaves of Premna recinosa afforded six flavonoids: quercetin, luteolin, pachypodol, chrysosplenol-D, naringenin and eriodictyol and three lignans: {+)-8-hydroxy-pinoresinol, {+)-lariciresinol and {-)-seco-isolariciresinol. Portulaca oleracea and Pentas schimperiana are used in the folk medicine as local anaesthetics. Studies on the isolated nerve and/or muscle preparations showed that extracts do block nerve conduction in these excitable tissues. A subsequent systematic bioassay-guided fractionation of crude extracts showed that excess potassioum ions in the extracts were responsible for the in vitro pharmacological activity of P. oleracea and P. schimperiana. Extracts from the leaves of Leonotis ocymifolia var raineriana showed no antibacterial activity. Three novel diterpenes: ent- {13S)-9,13α-epoxylabda- 6{ 19),β,16{15)-diol dilactone, (13R)-6,β-acetoxy-9, 13α-epoxylabda-19(20),8,16{ 15)- diol dilactone and 20,8-acetoxy-9α,13e-dihydroxy-15(16)-epoxy-Iabd-14-en-6,19,(β- O-lactone together with a known compound: {13S)-20,β-acetoxy-9,13α-epoxylabda- 6(19),β,16{15)-diol dilactone were isolated. Investigation of the root afforded two known compounds 3-methoxy-4-hydroxy-{trans)-cinnamaldehyde and 3-methoxy- 4-hydroxy-bezaldehyde.

Abstract:
This thesis describes investigations of the usage of unconventional therapeutic methods to treat diabetes mellitus, with particular reference to Asian patients. Findings suggest that usage of unconventional therapeutic methods may persist in diabetic patients regardless of their language, religious belief, ethnic and cultural background or psychological states and adherence. The thesis is presented in two parts. Study 1, a preliminary study, was conducted in Thailand. Groups of adults with diabetes mellitus, aged 17 - 70+ years, were studied to assess the extent to which unconventional therapeutic methods were used, and to examine the possibility that such usage is associated with their psychological states and unsatisfactorily feelings toward orthodox medicine. Data collection was achieved through a combination of well-established and well-evaluated questionnaires and a structured interview. A scale to assess attitudes to diabetes was found to be reliable in this sample, but scales to measure diabetes knowledge and treatment satisfaction were not. Study 2 was a study of British Indo-Asians in Foleshill, Coventry, England. The extent to which medicinal plants were used was explored and compared between two different cultural and religious backgrounds of adults with diabetes: (1) born in an Asian country and (2) born in England. The majority of participants were old with low educational background and income. A number of modifications were made to the structured interview used in study 1 to make it more appropriate for this sample. The two studies suggest that usage of medicinal plants is common among diabetics in Thailand and among British Indo-Asian diabetics born in an Asian country. Only a minority of users of medicinal plants in both countries were willing to discuss their usage of medicinal plants with their physicians. This could be because users believed that their physicians might not approve the usage of non-orthodox treatment. In Thailand, usage of medicinal plants was significantly associated with one factor - a lack of basic diabetes knowledge. In the study in England, a typical user was characterised as an Asian female born in an Asian country, who had a low income, used betel-nut, had a preferencef or a doctor's ethnicity, and had low treatment satisfaction and adherence scores.

Abstract:

Early man dabbled with the use of plant extracts to cure ailments. This practice has been passed down from generation to generation and today more than 50% of the world'sdrugs are natural products or derivatives thereof. Scientists have thus established a branch of research called natural product research. This branch of research involves the identification and purification of secondary metabolites with a specific biological activity. The methodology involves the screening of plant products for a specific biological activity, purification of the biologically active natural product by separation technology and structure determination. The biologically active natural products is then further scrutinized to serve as a novel drug or lead compound for the development of a novel drug. This research exploited this research methodology.

Abstract:
>Magister Scientiae - MSc
Research into traditional medicines is often conducted in a multidisciplinary approach as motivated by a desire to understand them in as complete a manner as possible,realizing their chemistry, biology and pharmacology. One biological approach involves monitoring the cytotoxicity of the extracts of subfractions against the nauplii,Artemia salina (brine shrimp). Organic and aqueous extracts of seven South African medicinal plants was investigated for biological activity. Selected plant extracts was also evaluated for AChE inhibitory activity. The objectives of this study was to look for any correlation between known biological activities of the investigated plants and BSLT lethality data and also to look for any correlation between AChEI activity and BSLT lethality data for selected plant extracts. The most active of the plants was the n-hex extract of T.alliacea, followed by the aqueous extract of C.mellei and the MeOH extract of C.quadrifidus; the MeOH and the DCM extracts of A.afra; the DCM extract of P.undulatum and the EtOAc extract of A.annua. The results from this study show a good correlation with antitumor, antimicrobial and anti-trypanocidal activity.The various plants extracts investigated showed good inhibitory activity towards AChE using the TLC bioautography method. The results obtained from this study indicate that this type of activity is not only subject to plants containing alkaloids, but rather a diverse class of compounds may exhibit this kind of activity. The extracts that showed good AChE inhibitory activity also showed good cytotoxicity towards brine shrimp nauplii.
