Keywords:

Four flavone glycosides including apigenin 7-O-β-glucoside (1), chrysoeriol 7-O-β-glucoside (2), rhoifolin (3), and 3′-methoxyapiin (4) were isolated from the n-butanol extract of the whole plant Uraria crinita collected in the phu Tho province, Vietnam. Their structures were elucidated by 1D- and 2D-NMR spectra and compared with those reported in the literature. Compounds 1-3 were obtained from the genus Uraria for the first time.
