Abstract
Six antioxidative compounds in the aerial parts of Potentilla fragarioides were isolated by a bioassay guided purification using a DPPH free radical. They were identified as (+)-catechin, isoquercitrin, quercitrin, quercetin-3-O-β-D-glucopyranosyl-β-D-xylopyranoside, caffeic acid, and 4-O-caffeoyl-L-threonic acid on the basis of 1H and 13C-NMR and MS data. The DPPH radical scavenging activity of five compounds (RC50: 7.5- 10.5 μg) except for quercitrin (16 μg) was more effective than those of α- tocopherol (12 μg) and BHA (14 μg).
