The present study was conducted to explore the hidden potential of natural products synthesized in the medicinal plant Tinosporacordifolia. This plantis prioritized by National Medicinal Plant Board, New Delhi. Leaf and inter nodal segments were inoculated on MS Medium fortified with IBA (1.0 mg/L) produced callus after four weeks. The calli were brown due to phenolic substance secreted by the explant. This problem was overcome by using adjuvant PVP (0.1%). Further, secondary metabolites were isolated from callus and field leaf through soxhlet extractor and fractionated by using column chromatography. The antibacterial activity of these fractioned extracts from Tinosporacordifolia callus and leaf were seen against multi drug resistance bacteria viz., Escherichia coli (ATCC 25922), Pseudomonas aeruginosa, (ATCC 27853) & Staphylococcus aureus (ATCC 29213) and against plant pathogenic fungus Fuseriumoxisporum(MTCC 8608) and Sclerotiniasclerotiorum (MTCC 8785). All fractionated extracts showed antimicrobial activity but callus extracts were proved to be best in compare to leaf extracts. Furthermore, we are trying to analyze different bio active compounds through GCMS.
