摘 要 ：从重楼属植物五指莲Paris axialis H.Li．根茎中分离到三个甾体皂甙，经化学降解，质谱，核磁共振谱分析，证明其中两个甙为新的化合物，即偏诺皂甙元-3－O-β-D葡萄毗哺糖基(1→3)[α-L鼠李吡喃糖基(1→2)]-β-D-葡萄吡喃糖甙和24α-羟基偏诺皂甙元-3－O-β-D-葡萄吡喃糖基(1→3)][(α-L鼠李吡喃糖基(1→2)]3-β-D-葡萄吡喃糖； 另一个鉴定为薯等皂式元-3-O-β-D-葡萄吡喃糖基(1→3)[α-L-鼠李毗哺糖基(1→2)]〕-β-D-葡萄吡喃糖甙。

Abstract:Two new steroidal glycosides, pennogenin- 3 -O-β-D--glucopyranosyl(1 →3 ) [α-L-rhamnopyranosyl (1→ 2 ) ] -β-D-glucopyranoside (I ), 24α-hydroxyl- pennogenin- 3 -O-β-D-glucopyranosyl (1→ 3 )[α-L-rhamnopyranosyl(1 → 2 )] -β-D-glucopyranoside (III), and diosgenin- 3 -O-β-D-glucopyranosyl (1 →3 ) [α-L-rhamnopyranosyl (1→ 2 )]-β-D-glucopyranoside (II ) were isolated from dried rhizoma of Paris axialis H.Li, which is new species in Yunnan. Their structtlres were deterrnined by means of the spectral analysis (l3C NMR and MS). The sapogenin of (III)was elucidated as 24α-hydroxyl-pennogenin and it is a new sapogenin. It is interesting that all of them have same glycosyl groups and is only different in aglycone moiety.
