Due to overexploitation from the natural resources, an efficient regeneration protocol for medicinally important and rare plant species, Atropa acuminate for conservation was developed. Leaf explants were inoculated on MS medium supplemented with different concentrations of BAPfor callus induction and organogenesis. After one and a half week, callus induction was recorded with the highest frequency at 3mg/l BAP. After 3 weeks of subsequent sub-culturing, optimum shoot induction frequency of 100% was achieved at 3mg/l BAP. Also, highest mean shoot numbers per explant (15.2) were recorded at the same concentration. Successful in vitro rooting of the microshoots was achieved on MS medium fortified with(0.5mg/l)IBA. The regenerated shoots with well developed roots were successfully acclimatized in vermicompost and hardened with 100% survival rate under greenhouse conditions. Furthermore, methanolic extract of in vitro regenerated plants were screened forimportant secondary metabolites and antioxidant potential. Alkaloids, phenolics, flavonoids and terpenes were present abundantly. Also, the plants revealed antioxidant activity in dose dependent manner. Current study can serve as an efficient protocol for mass multiplication and conservation of medicinally important plant A. acuminata.
