中药白头翁化学成分的研究(Ⅰ)

Studies on the Chemical Constituents of Pulsatilla Chinensis(Ⅰ)

从中药白头翁(Pulsatilla chinensis(Bunge)Regel)的根茎中分离出一种三萜皂甙成分,经化学和光谱法确定为3-O-α-L-吡喃鼠李糖-(1→2)-α-L-吡哺阿拉伯糖-3β,23-二羟基-△^(20(29))-羽扇豆烯-28-酸,为一新化合物。

A new triterpenoid glycoside (Ⅰ) has been isolated from Pulsatilla chinensis (Bunge) Regel. The structure of Ⅰ has been elucidated as 3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl-3β, 23-dihydroxylup-20(29)-en-28-oic acid by spectroscopic and chemical means.
