摘要
从南柴胡(BupleurumscorzonerifoliumWild.)根中分得5个三萜皂甙。根据理化性质和波谱数据,鉴定其中新皂甙为3β,16α,23,28四羟基齐墩果烷11,13(18)二烯3OβD吡喃葡萄糖基(1→6)[αL吡喃鼠李糖基(1→4)]βD吡喃葡萄糖甙,命名为柴胡皂甙s(saikosaponins)。另4个皂甙分别为柴胡皂甙a、c、b1、b2。
Five saikosaponins were isolated from the roots of Bupleurum scorzonerifolium Willd. A new saikosaponin was elucidated as the 3β, 16α, 23, 28tetrahydroxyoleana11,13(18)dien3OβDglucopyranosyl(1→6)[αLrhamnopyranosyl(1→4)]βDglucopyranoside on the basis of spectral analysis and named as the saikosaponin s. The other four saikosaponins were determined as the saikosaponin a, saikosaponin c, saikosaponin b1 and saikosaponin b2.
