Isolation and Structure Elucidation of Radical Scavengers from Chrysanthemum boreale Makino

Two antioxidative compounds in Chrysanthemum boreale were isolated by a bioassay using a 2, 2-diphenyl-1-picrydrazyl(DPPH) free radical. They were identified as apigenin, linarin(acacetin-7-O-rutinoside) on the basis of and MS data. The DPPH radical scavenging activity of apigenin was similar to that of and L-ascorbic acid
