Three flavonoids and three saponins have been isolated from Oxytropis species. Their structures were determined as isorhamnetin-3-O-beta-D-glucoside, rhamnetin-3-O-beta-D-galactoside, apigenin, 3-O-[alpha-L-rhamnopyranosyl (1----2)-beta-D-glucopyranosyl(1----4)-beta-D-glucuronopyranosyl]+ ++soyasapogenol B, 3-O-[beta-D-glucopyranosyl(1----2)-beta-D-glucuronopyranosyl] azukisapogenol and a new saponin 3-O-[beta-D-glucopyranosyl(1----2)-beta-D-glucopyranosyl]-25-O-alpha-L- rhamnopyranosyl-(20S,24S)-3 beta,16 beta, 20,24,25-pentahydroxy-9,19-cycloanostane.
从棘豆属植物中分离出了三种黄酮类化合物和三种皂苷。它们的结构被确定为异鼠李素-3-O-β-D-葡萄糖苷、鼠李素-3-O-β-D-半乳糖苷、芹菜素、3-O-[α-L-鼠李糖基(1→2)-β-D-葡萄糖基(1→4)-β-D-葡萄糖醛酸基]大豆皂醇B、3-O-[β-D-葡萄糖基(1→2)-β-D-葡萄糖醛酸基]赤豆皂醇以及一种新的皂苷3-O-[β-D-葡萄糖基(1→2)-β-D-葡萄糖基]-25-O-α-L-鼠李糖基-(20S,24S)-3β,16β,20,24,25-五羟基-9,19-环羊毛甾烷。
