摘要：

A methanolic extract of Platanus acerifolia buds yielded the known components kaempferol 3-rhamnoside, 7-rhamnoside and 3-glucoside. The ethyl acetate extract afforded tiliroside and a new glycoside, kaempferol 3-(2,3-di-E-p-coumaroyl-α-l-rhamnopyranoside), platanoside. Separations were made by column chromatography, centrifugal TLC HPLC. Structure elucidation was achieved by UV, 1H, 13C NMR and mass spectra. This is the first report of a flavonoid 2″,3″-di-cinnamoylglycoside. © 1990.
