[Study on the flavanone constitutes of Buddleja davidii].Zhong Yao Cai. 2011 Oct; 34(10):1534-7.ZY
To study the chemical constitutes of Buddleja davidii.
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.
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).
All these compounds are obtained from this plant for the first time.
