Abstract

OBJECTIVE

To investigate the chemical constituents in the leaves of Lindera aggregate.

METHODS

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).

RESULTS

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).

CONCLUSION

Compounds 2,4 and 8 are obtained from Lindera aggregata for the first time.
