Xuejing Peng, Chong Li

Abstract

OBJECTIVE: To study the chemical constitutes of Buddleja davidii. METHODS: The constitutes were isolated and purified by silica gel column chromatography, polyamide column chromatography and macroporous absorption resin and their structures were elucidated by spectroscopic analysis. RESULTS: Seven compounds including Apigenin (1), Apigenin-7-O-beta-D-glucoside (2), Acacetin (3), Acacetin-7-O-beta-D-glucoside(4), Acacetin-7-O-alpha-L-rhamnopyranosyl-(1-6)-beta-D-glucopyranoside (5), Luteolin (6), Luteolin-7-O-beta-D-glueoside (7). CONCLUSION: All these compounds are obtained from this plant for the first time.
