INTRODUCTION India has immense wealth of biodiversity concisely, its having 10 biogeographical regions and also it is renowned as one the world’s top 12 mega biodiversity nations, In this view of the considerations, biodiversity is facts for chemical diversity and reliable phytochemical sources for the discovery of new drugs. Therefore, recent years the growing clinical demands on motivating the biomedical technology to searching for the new therapeutic compound depends upon the biodiversity of the nations. Over 70% of new valuable chemical substance (New Chemical Entities - NCEs) introduced into remedial practice to test the quality of the product and also they can play a vital role in drug development of Pharmaceutical industry were derived from natural products from plant origins. Solanum incanum L. (Family – Solanaceae) Synonyms: Solanum panduriforme E. Mey. Solanum bojeri Dunal. Vernacular Name is Mullakathirikkai, with Common name is Indian nightshade, thorn apple, bitter apple, bitter ball and bitter tomato. It is a nightshade family that is native to sub – Saharan Africa and grown in many regions of Far East Asia, Africa, and Middle eastwards to India. The Plant is an erect or spreading perennial shrub small prickle in leaves and stems. They creepy in nature, leaves are arranged in alternate, usually simple and lack stipules. In nature, the flowers are actinomorphic of only slightly zycomorphic. The young green and ripened fruits are yellow coloured. It is found that effective in treating various ailments such as, throat like a sore throat, angina, stomachache, painful menstruation, liver pain, pneumonia and rheumatism and it is having antimicrobial and anti-tumor activities. For these purposes, leaf, root and fruit decoctions are drunk, roots are chewed and sap swallowed, leaf sap is used for washing painful areas, and ash of burnt plants is mixed with fat and applied externally. In the present investigation, we are concluding that a screening of phytochemicals (Alkaloids, Flavanoids, Saponins, Phenols, Phytosterols with anodes, Glycosides, Triterpenoids, Tannins, Anthaquinones, Carbohydrates and steroids) and Phytonutrients constituents (Na, Al, Mg, Mn, P, Cl, K, CA, Fe, Cu and Zn) from Solanum incanum plant root, stem, leaves and fruits by Scanning Electron Micrographic with Energy Dispersive Spectroscopic analysis were made (SEM-EDS). 2. MATERIALS AND METHODS 2. 1. Source of Plant collections The Plants were collected in Southern Western Ghats Ecoregions of the Nilgiri Biosphere Reserve.

Twelve male and female Wistar Albino rats were randomly assigned into four groups of three rats each, following acclimatization to laboratory and handling conditions. Diabetes was induced with a single dose of alloxan (120 mg/kg) body weight and plasma glucose was taken 72 h after induction to confirm diabetes. The normal control was not induced. Animals in group a (normal control) and B (diabetic) were administered 0.5 ml of normal saline respectively. Group C was administered with 10 mg/kg weight of glibenclamide and group D was administered 500 mg/kg body weight of aqueous Solanum incanum extract. Extract administration lasted for fourteen days. Water and feeds were allowed ad libitum. After the two weeks treatment with the plant extract, blood samples were collected by cardiac puncture for lipid profile analysis by standard methods and enzyme kits. At the end of week two, the lipid profile of all groups were significantly different. The result on lipid profile showed that the extract treated group was significantly lower (P>0.05) in TC, TAG and VLDL as compared to diabetic control but significantly higher (P<0.05) in HDL and LDL as compared to diabetic control.

  • The Gradual Loss of African Indigenous Vegetables in Tropical America: a Review
    The Gradual Loss of African Indigenous Vegetables in Tropical America: A Review 1 ,2 INA VANDEBROEK AND ROBERT VOEKS* 1The New York Botanical Garden, Institute of Economic Botany, 2900 Southern Boulevard, The Bronx, NY 10458, USA 2Department of Geography & the Environment, California State University—Fullerton, 800 N. State College Blvd., Fullerton, CA 92832, USA *Corresponding author; e-mail: [email protected] Leaf vegetables and other edible greens are a crucial component of traditional diets in sub-Saharan Africa, used popularly in soups, sauces, and stews. In this review, we trace the trajectories of 12 prominent African indigenous vegetables (AIVs) in tropical America, in order to better understand the diffusion of their culinary and ethnobotanical uses by the African diaspora. The 12 AIVs were selected from African reference works and preliminary reports of their presence in the Americas. Given the importance of each of these vegetables in African diets, our working hypothesis was that the culinary traditions associated with these species would be continued in tropical America by Afro-descendant communities. However, a review of the historical and contemporary literature, and consultation with scholars, shows that the culinary uses of most of these vegetables have been gradually lost. Two noteworthy exceptions include okra (Abelmoschus esculentus) and callaloo (Amaranthus viridis), although the latter is not the species used in Africa and callaloo has only risen to prominence in Jamaica since the 1960s. Nine of the 12 AIVs found refuge in the African- derived religions Candomblé and Santería, where they remain ritually important. In speculating why these AIVs did not survive in the diets of the New World African diaspora, one has to contemplate the sociocultural, economic, and environmental forces that have shaped—and continue to shape—these foodways and cuisines since the Atlantic slave trade.

  • Location of Chlorogenic Acid Biosynthesis Pathway
    Gramazio et al. BMC Plant Biology 2014, 14:350 http://www.biomedcentral.com/1471-2229/14/350 RESEARCH ARTICLE Open Access Location of chlorogenic acid biosynthesis pathway and polyphenol oxidase genes in a new interspecific anchored linkage map of eggplant Pietro Gramazio1, Jaime Prohens1*, Mariola Plazas1, Isabel And?jar 1, Francisco Javier Herraiz1, Elena Castillo1, Sandra Knapp2, Rachel S Meyer3,4 and Santiago Vilanova1 Abstract Background: Eggplant is a powerful source of polyphenols which seems to play a key role in the prevention of several human diseases, such as cancer and diabetes. Chlorogenic acid is the polyphenol most present in eggplant, comprising between the 70% and 90% of the total polyphenol content. Introduction of the high chlorogenic acid content of wild relatives, such as S. incanum, into eggplant varieties will be of great interest. A potential side effect of the increased level polyphenols could be a decrease on apparent quality due to browning caused by the polyphenol oxidase enzymes mediated oxidation of polyphenols. We report the development of a new interspecific S. melongena ? S. incanum linkage map based on a first backcross generation (BC1) towards the cultivated S. melongena as a tool for introgressing S. incanum alleles involved in the biosynthesis of chlorogenic acid in the genetic background of S. melongena. Results: The interspecific genetic linkage map of eggplant developed in this work anchor the most informative previously published genetic maps of eggplant using common markers. The 91 BC1 plants of the mapping population were genotyped with 42 COSII, 99 SSRs, 88 AFLPs, 9 CAPS, 4 SNPs and one morphological polymorphic markers.

Leptostemonum (Dunal) Bitter sect. Melongena Dunal were produced in order to assess inherent nuclear and non-nuclear influences on hybrid fitness, the extent of genomic change, and species compatibility. Hybrids expressed intermediacy and overlaps in leaf, petiole, petal, and plant height dimensions. Maternal influence was dominant in growth habit, leaf shape and texture, flower colour, and fruit size, while paternal control was limited to fruit colour in Solanum gilo × S. macrocarpon. Pollen viability was reduced from 97.3%-86.5% in parents to 53.8%-20.5% in hybrids. S. gilo × S. macrocarpon produced single- flowered inflorescence, whereas the reciprocal S. macrocarpon × S. gilo developed the ability to perennate, indicating the heterogeneity of the parental genome. Fruits of the hybrids were intermediate or smaller, and had fewer seeds. They were wrinkled in S. gilo × S. macrocarpon, with many aborted seeds. Meiosis was irregular, with few laggards, and isolated uni- and bivalent chromosomes associated with foreign genes in the parent species. Conversely, multivalent and chromosome clumps revealed the extent of homogenization of the parental genomes and species affinity.

  • Ethno- Medicinal and Conservation Studies on the Indigenous Vegetables in Akinyele Local Government Area of Oyo State, Nigeria
    Ethno- medicinal and Conservation Studies on the Indigenous Vegetables in Akinyele Local Government Area of Oyo State, Nigeria Modupe Janet Ayeni1, Joshua Kayode2, Christiana Olaide Oladele3 1,2,3Department of Plant Science and Biotechnology,Ekiti State University, Ado-Ekiti, Nigeria [email protected] Abstract: The ethno- medicinal and conservation status of indigenous vegetables in Akinyele Local Government Area (LGA) of Oyo State, Nigeria were examined with a view to evolving strategies that will conserve them. A combination of social surveys and direct field observations was used. Farm and market surveys were conducted. Five farm settlements and three major markets were used. 10 each of farmers and vegetable vendors were randomly selected and interviewed with aid of semi-structured questionnaire matrix to obtain information on the vegetables in the farms and those sold in the markets. Results obtained suggested the existence of gender specificity in agricultural activities in the study area. Women were responsible for the cultivation, harvest and haulage of vegetables. A total of 33 vegetables belonging to 18 families were identified in the study area. 21 were sampled in farm settlements and markets, 11 in farm settlements only and 1 in market only.
