Phytochemical analysis and free-radical scavenging activity of

摘要

ABSTRACT The present investigation is to evaluate the antioxidant activity of various extracts of root and leaf of F. strobilifera using different in vitro methods and its phytochemical analysis. The antioxidant activity was studied by DPPH radical scavenging method, nitric oxide radical inhibition assay and scavenging of hydroxyl radical by p-NDA method. Methanolic extract of root and leaf of F. strobilifera showed a very good DPPH radical scavenging activity with low IC50 values of 11.4 .
