STUDIES ON THE CHEMICAL CONSTITUTENS OF VICIA AMOENA FISCH

One new flavonoide was isolated from Vicia amoena Fisch. On the basis of spectral(UV,MS,NMR)and chemical reactions, it was elucidated to be kaempferol-3-O-β-D-mannoside, named amoenin(A₃). Moreover, five known compounds have been isolated and identified as quercetin, kaempferol, quercetin-3-O-α-L-rhamoside, quercetin3-O-β-D-glucoside, kaempferol-3,7-O-α-L-dirhamoside. The total flavonoides showed significant effects on inducing hyperlipidemia and increasing micro-blood vessel elasticity.
