Abstract
The aim of the present study was to investigate the presence of phyto chemical, antimicrobial activities and micro propagation of the selected medicinal plants i.e. Rauwolfia serpentina, Adhatoda vasica and Alstonia scholaris. These endemic plants belong to Apocynaceae and were collected from higher altitudes of Eastern Ghats, Lambasingi forest region, Andhra Pradesh India. To determine the total phenolic and flavonoid contents, Soxhlet apparatus was used for this study. Solvents used were in this study are water, ethyl acetate, chloroform and methanol. Among them the solvent methanolic extract of Rauwolfia serpentina (57.15±1.2) and Alstonia scholaris (55.06±0.7) showed high content of saponins. The test microrganism which were studied against the efficacy of selected medicinal plant extracts were, two bacterial strians i.e., Streptococcus pyogenes, Pseudomonas aeruginosa and two fungal strains Aspergillus niger and Vibrio cholera. The antimicrobial activity was proved that the methanol extracts was found to be maximum antimicrobial growth inhibition. The simple and effective protocol was developed to propagate the Rauwolfia plant from nodal explants. Maximum no of 95% plantlets regenerated successfully. These propagated plantlets were hardened to survive in vivo conditions.
