摘要: 从滇重楼中分离得到2个甾体皂苷,利用1H NMR、13C NMR、1H-1H COSY、HSQC、 HMBC、1D和2D TOCSY等多种核磁共振方法鉴定其结构分别为(25R)-26-O-β-D-吡喃葡萄糖基-3β, 22α, 26-三羟基-呋甾-5-烯- 3-O-α-L -吡喃鼠李糖基-(1→2)[α-L-呋喃阿拉伯糖基(1→4)]-β-D-吡喃葡萄糖苷(1, Parisaponin I)和(25R)-3β, 5α, 6β-三羟基-△7-螺甾烯-3-O-β-D-吡喃葡萄糖基-(1→3)[α-L-吡喃鼠李糖基-(1→2)]-β-D-吡喃葡萄糖苷(2, parisvietnaside A). 对化合物1和2的1H NMR和13C NMR信号分别进行了归属和详细分析,并纠正了文献中的核磁数据归属错误. 化合物2为首次从滇重楼中分离得到. 

Abstract: Two steroidal saponins were isolated from the rhizome of Paris polyphyllaSmith var. yunnanensis. Their structures were elucidated as (25R)-26-O-β-D-glucopyranosyl-3β, 22α, 26-trihydroxy-furost-5-ene-3-O-α-L-rhamnopyranosyl-(1→2)-[α-L-arabinofuranosyl-(1→4)]-β-D-glucopyranoside (1, parisaponin I) and (25R)-3β, 5α, 6β-trihydroxy-7(8)-ene-spirostanol-3-O-β- D-glucopyranosyl-(1→3)-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside (2, parisvietnaside A) by MS, 1D and 2D NMR spectroscopy. The 1H and 13C chemical shifts of the compounds were assigned, and the incorrect assignments in previous literatures were corrected. Compound 2 was isolated from the plant for the first time.

Key words: NMR, chemical shift, 2D NMR, steroidal saponin, Paris polyphylla Smith var. yunnanensis
