Abstract

To investigate the chemical constituents in the leaves of Lindera aggregate. Compounds were separated by column chromatography with silica gel and ODS. The structures were identified by physicochemical properties and spectral analysis (1H-NMR, 13C-NMR). Eight compounds were isolated and identified as: quercetin-3-O-L-rhamnoside(1), kaempferol-3-O-L-rhamnoside(2), kaempferol(3), dihydrokaempferol-3-O-L-rhamnoside (4), quercetin (5), quercetin-3-O-alpha-D-arabinofuranoside (6), quercetin-3-O-alpha-D-glucopyranoside(7), kaempferol-3-O-D-glucopyranoside(8). Compounds 2,4 and 8 are obtained from Lindera aggregata for the first time.
