These plants are mainly distributed in north eastern (NE) zones of India. Extracts of the aerial and/or underground parts have been applied in traditional medicine for the treatment of different diseases, hence they have gained sufficient importance in Alternate medicinal therapy. The the antioxidant activities of extracts was evaluated in vitro systems to gain mechanistic insights. Results from antioxidant assays together with authentic antioxidant standards revealed that aqueous extract (AqEx) showed strong radical scavenging ability.
