Objective: The aim of the present study was to develop a callus induction protocol and comparative study of therapeutic phytochemicals present in in vivo leaf and in vitro callus extracts through Gas Chromatography-Mass Spectrometry analysis.Methods: Murashige and Skoog media was used as culture media for callus induction. In vitro callus induction protocol was developed by studying the effects of various plant growth regulators like auxin, 2, 4-D (2,4-dichlorophenoxyacetic acid), NAA (naphthalic acetic acid), alone and in combination with cytokinin BAP (benzyl aminopurine), on leaf and stem explants. The GC-MS analysis of Ampelocissus latifolia was carried out on Shimadzu QP-2010 plus with thermal desorption system TD 20 to study the phytochemical profile.Results: In vitro callus induction protocol was developed for the plant and callusing was done from leaf and stem explants of Ampelocissus latifolia. The best result for callus induction was obtained using leaf explant, and callus production were maximum in Murashige and Skoog medium fortified with BAP (0.5 mg/l) and NAA (1.0 mg/l). Major compounds identified in the GC-MS analysis were Campesterol, Stigmasterol, Beta-Sitosterol, Docosanol, Dodecanoic acid, etc., in in vitro extract and Beta Sitosterol, Tocopherol, Squalene, Bergamot oil, Margarinic acid, Hexadecanoic acid, etc., in in vivo extract. The different active phytochemicals identified have been found to possess a wide range of biological activities, thus this analysis forms a basis for the biological characterization and importance of the compounds identified for human benefits.Conclusion: This is the first report on callus induction in Ampelocissus latifolia. From the results obtained through the in vitro callus induction and its comparative GCMS analysis with in vivo extract, it is revealed that Ampelocissus latifolia contains various bioactive compounds that are of importance for phytopharmaceutical uses. The GCMS analysis revealed that the amount of Beta-sitosterol and 5-Hydroxymethylfurfural (HMF) was very high in in vitro extract as compared to in vivo extract.

The present study was carried out in two geographically isolated Hillocks, Sacred Groves and Unclassified Vegetation of Gingee Taluk of Villupuram district, Tamil Nadu, India, a region inhabited by farmers and tribal groups. Data obtained through guided field-walk method on ethnomedicinal plants and ethnographic profile of respondents was documented using semi structured questionnaires. Information on medicinal plants with their correct botanical identities with family, local names, parts used, is carefully recorded. It resulted in about 50 medicinal plants used for the treatment of several diseases either in single or in combination with some other ingredients. The survey shows that the informants in two villages have very good knowledge about the medicinal plants used for various ailments. This present study analyzed the data collected from the study area by applying the quantitative ethnobotanical devices such as, Use value (UVi), Factor informant consensus (Fic) and Fidelity level (Fl%).

In the recent years, tissue culture has emerged as a promising technique to obtain genetically pure elite populations under in vitro conditions. The Cleome viscosa are used in traditional systems of medicine for the treatment of many diseases in human. The present study aims to investigate the role of assorted plant growth regulators (PGRs) on in vitro propagation and comparison of similar and dissimilar compounds of wild plant C. viscosa. Nodal explants of 1.5-2.0 cm were used to induce multiple shoots in Murashige and Skoog (MS) medium supplemented with various concentration of different plant growth regulators (PGRs) such as 6 -Benzylaminopurine (BAP), Kinetin (KIN), Naphthalene-3-acetic acid (NAA) and the bioactive constituent of wild and in vitro propagated C. viscosa plant was compared by analyzing polar and non polar extract of both the plants using Gas Chromatography -Mass Spectrometry (GC-MS) analysis. Multiple shoots were initiated within 28 days of inoculums and the various concentration of PGR had a significant role in the number of shoot formed and the in vitro regeneration of explants. The regenerated plantlets showed no morphological differences from the wild plant but the GC-MS analysis of ethanol extract showed the presence of eight compounds in wild plant and six in micropropagated while chloroform extract showed ten compounds in both plants.
