摘要
自长梗绞股蓝(GynostemmalongipesC.Y.Wu)的地上部分分得一个新的三萜皂甙,经化学方法和光谱分析确定其化学结构为19氧化3β,20(S),21三羟基达玛烷24烯3O{[αL吡喃鼠李糖基(1→2)][βD吡喃木糖基(1→3)]}αL阿拉伯糖甙,命名为长梗绞股蓝皂甙I(gylongiposideI)。
A new triterpenoid saponin named gylongiposide I was isolated from the aerial parts of Gynostemma longipes C.Y.Wu. On the basis of chemical evidence and spectral data the structure of gylongiposide I was elucidated as 19 oxo 3β,20( S ), 21 trihydroxydammar 24 ene 3 O {[α L rhamnopyranosy(1→2)][β D xylpyranosyl(1→3)]}α L arabinopyranoside(G). The known compounds were identified as gypenoside XLIX(F) and ginsenoside Rb 1(A).
