摘要
从中药白头翁的根中,分得5个甙类成分。根据化学反应和光谱分析,其中的4个分别被鉴定为:胡萝卜甙(Ⅰ),白头翁皂苷A_3(Ⅱ),3-O-α-L-吡喃阿拉伯糖-3β,23-二羟基-Δ^(20(29))-羽扇豆烯-28-O-α-L-吡喃鼠李糖-(1→4)-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖甙(Ⅲ)和白头翁皂苷B_4。其中Ⅲ是一个新的三萜皂甙,命名为白头翁皂甙B(Pulchinenoside B)。
Five glycosides were isolated from Chinese Drug "Bai-Tou-Weng", the dried root of Pulsatilla chinensis (Bunge) Regel. On the basis of chemical and spectroscopic analysis four of them were identified as daucosterol (Ⅰ), anemoside A_3(Ⅱ), 3-O-α-L-arabinopyranosyl-3β, 23-dihydroxylup-20(29)-en-28-O-α-L-rhamnopyransyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside (Ⅲ) and anemoside B_4 (Ⅳ), respectively. Ⅲ is found to be a new triterpenoid saponin named pulchinenoside B.
