摘要: 从圆果雪胆(Hemsleya amabilis)的块茎中分离到10个化合物,其中3个雪胆皂甙是首次从该种植物中得到,它们的结构通过光谱和化学的方法鉴定为齐墩果酸-3-O-α-吡喃阿拉伯糖(1→3)- β-葡萄糖醛酸甙,28-O-β-D-吡喃葡萄糖齐墩果酸3-O-α-吡喃阿拉伯糖(1→3)- β-D-葡萄糖醛酸,28-O-β-D-吡喃葡萄糖齐墩果酸3-O-[β-D-吡喃葡萄糖(1→2)]-[α-吡喃阿拉伯糖(1→3)]- β-D-葡萄糖醛酸。同时还得到雪胆甲素,雪胆乙素,雪胆乙素甙,齐墩果酸和β-谷甾醇等。

Abstract: From the rhizomes of Hemsleya amabilis,three sapionins of oleanolic acid were isolated,named hemslosides-Am1,-Mal and Ma3. Their structures have been elucidated as 3-O-α-arabinopyranosyl(1→3)- β-glucuronide of oleanolic acid,28-O-β-D-glucopyranosyl ester of oleanolic acid 3-O-α-arabinopyranosyl(1→3)- β-glucronide and 28-O-β-D-glucopyranosyl ester of oleanolic acid 3-O-[β-D-glucopyranosyl(1→2)]-[α-arabinopyranosyl(1→3)]- β-glucuroide respectively.In addition,cucurbitacins,cucurbitacin II gkycisude,oleanolic acid and β-sitosterol were obtained.
