摘要
从圆果雪胆 (Hemsleyaamabilis)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 ,2 8-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 ,2 8-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
From the rhizomes of Hemsleya amabilis , three saponins of oleanolic acid were isolated, named hemslosides-Am1, -Ma1 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-glucuronide and 28-O-β-D-glucopyranosyl ester of oleanolic acid 3-O-[β-glucopyranosyl(1→2)]-[α-arabinopyranosyl(1→3)]-β-glucuronide, respectively. In addition, cucurbitacins, cucurbitacin Ⅱ glycoside, oleanolic acid and β-sitosterol were obtained.
