摘 要 ：从盾叶薯蓣Dioscorea zingiberensis Wright地上部分分离鉴定了四个甾体皂甙，经鉴定甙A为约莫皂甙元-3-O－[α－L-鼠李吡喃糖基(1→2)]-β-D-葡萄吡哺糖甙；甙B为24α-羟基约莫皂甙元-3-O-[α-L-鼠李吡喃糖基[(l→2)β-D-葡萄吡喃糖甙；甙C为约莫皂甙元3-O-[α-L-鼠李吡喃糖基(1→2)][β-D-葡萄吡喃糖基(l→4)]β-D-葡萄吡喃糖基；甙D为约皂甙元-3-O-[ α-L-鼠李吡喃基(l→2)[β-D-葡萄吡喃糖基(1→3)]-β-D-葡萄吡喃糖甙。前三者为新化合物，分别命名为盾叶皂甙A1、A2 A3 (zingiberoside A1、A2、A3)，其中盾叶皂甙A2的甙元为新甾体皂甙元，命名为盾叶皂甙元(zingiberogenin)。

Abstract:From the aerial part of Dioscorea zingiberensis Wright,four steroidal saponins had been isolated. By chemical and physical methods,saponin A was identified as yamogenin-3-O－[α－L-rhamnophyranosyl(1→2)]-β-D-glucopy-ranoside,saponin B as 24α-OH-yamogenin-3-O-[α-L-rhamnophyranosyl[(l→2)β-D-glucopyranoside;SaponinC as yamogenin-3-O-[α-L-rhamnophyranosyl(1→2)][β-D-glucopyranosyl(l→4)]β-D-glucopyranoside and saponinDas yamogenin-3-O-[ α-L-rhamnophyranosyl(l→2)[β-D-glucopyranosyl(1→3)]-β-D-glucopyranoside.The saponins are new and named zigiberoside A1、A2 A3 respectively.
