摘要:
Two new C-glycosylflavones, named 5,7,3',4'-tetrahydroxy-6-methoxy-8-C-beta-D-gluco-pyranosyl flavonoside (1), 5,3',4'-trihydroxy-6,7-dimethoxy-8-C-[beta-D-apiofuranosyl-(1 -> 2)]-beta-D-glucopyranosyl flavonoside (2), together with nine known compounds (3-11), were isolated from 50% acetone extract of Boea hygrometrica (Bunge.) R.Br. Their structures were established by spectroscopic techniques including MS, IR, UV, and 2D NMR.
