Two compounds were obtained from the rhizome of Dioscorea zingiberensis Wright. One of them was elucidated as dioscin, the other one was a new compound and characterized as Spirost-5-en-3-yl beta-D-glucopyranosyl (1 --> 3)-beta-D-glucopyranosyl (1 --> 4)-[alpha-L-rhamnopyranosyl (1 --> 2)]-beta-D-glucopyranoside, structure was determined on the basis 2D NMR spectroscopic technique and the result of acid hydrolysis.
从盾叶薯蓣根茎中得到了两种化合物。其中一种被鉴定为薯蓣皂苷，另一种是新化合物，被表征为螺甾-5-烯-3-基 β-D-吡喃葡萄糖基(1→3)-β-D-吡喃葡萄糖基(1→4)-[α-L-鼠李吡喃糖基(1→2)]-β-D-吡喃葡萄糖苷，其结构是基于二维核磁共振波谱技术和酸水解结果确定的。
