Abstract

Objective: To evaluate the antioxidant, phytotoxic, antimicrobial, insecticidal, cytotoxic, antiglycative, and xanthine oxidase activities of different extracts of Suaeda heterophylla (S. heterophylla) and Bergenia stracheyi (B. stracheyi). Methods: The extracts of S. heterophylla and B. stracheyi were evaluated for antioxidant, phytotoxic, antimicrobial, insecticidal, cytotoxic, antiglycative, and xanthine oxidase activities using standard experimental methods. Results: The overall antioxidant potential of ethyl acetate extract of S. heterophylla was the strongest, followed by chloroform extract, methanolic extract and n-hexane extract. It is interesting to note that ethyl acetate fraction showed 94.98% inhibition at concentration of 60 µg/mL while standard ascorbic acid showed 98.49% inhibition at same concentration. The crude methanol extracts of S. heterophylla and B. stracheyi showed significant phytotoxic activity at the highest dose. Moreover, methanol extract of B. stracheyi possessed strong activity in xanthine oxidase enzyme inhibition. Conclusions: Antioxidant, phytotoxic, and xanthine oxidase activities of different fractions of S. heterophylla and B. stracheyi clearly demonstrate that these fractions possess great potential for the food, cosmetic and pharmaceutical industries.
