从云南产草药箭根薯的根茎分离鉴定了薯蓣皂甙元的α-L-鼠李吡喃糖-(1→2)-α-L-鼠李吡喃糖-(1→3)-β-D-葡萄吡喃糖甙,以及豆甾醇和胡萝卜甙。这一结果的分类学意义,在于支持 I.H.Burkill 及 A.Takhtajan 关于箭根薯科与薯蓣科亲缘关系较为密切的观点。
The α-L-rhamopyranose-(1→2)-α-L-rhamopyranose-(1→3)-β- of diosgenin was identified from the rhizome of the Chinese herb arrowroot potato from Yunnan. D-pyranoside, as well as stigmasterol and carrot tart. The taxonomic significance of this result lies in supporting I.H.Burkill and A.Takhtajan’s views on the close relationship between the potato roots and the Dioscoreaceae.
