Abstract

The antioxidant activities of extracts and residuum of Perillafrutescens fruits from supercritical CO2 extraction were determined in vitro. The residuum was extracted in turn with water, propyl alcohol and ethyl acetate. The antioxidant activities of the extracts were assayed with antioxidant capacity in linoleic acid model system, reducing powers, radical scavenging activity using 1,1-diphenyl-2-picrylhy-drazyl (DPPH) method. The results show that the ethyl acetate extract of Perillafrutescens possesses strongest DPPH radical scavenging activity and reducing power in a concentration-dependent manner.
