초록

From the EtOAc soluble fractions of Platanus orientals Linn leaves, (+)-catechin (1), (+)-epicatechin (2), (+)-gallocatechin (3), kaempferol (4), quercetin (5), kaempferol-3-O-${\alpha}$-L-rhamnopyranoside (6), quercetin-3-O-${\beta}$-D-glucopyranoside (7) and tyrosol (8) were isolated. The structures of the isolated compounds were characterized by NMR and MS spectrometers. The antioxidative activities of the isolated compounds and fractions were evaluated by DPPH free radical scavenging method and the results indicated that compounds 1, 2, 3, 4, 5 and EtOAc soluble fraction exhibited greater activities than ${\alpha}$-tocopherol and BHT, while compounds 6, 8 and other fractions showed low activity compared to the controls.
