【摘要】 利用Diaion HP20及硅胶柱层析进行化合物的分离,从乙酸乙酯萃取部位分离得到了4个化合物,借助多种光谱技术进行结构鉴定分别鉴定为(25R)-螺甾-5-烯-1β,3β-二醇1-O-{O-α-L-鼠李吡喃糖苷-(1→2)-O-[β-D-木糖吡喃糖苷-(1→3)]-β-D-岩藻吡喃糖苷}(ophiopogonin D,1),(25R)-ruscogenin1-O-[2-O-(乙酰基)-α-L-鼠李吡喃糖苷-(1→2)][β-D-木糖吡喃糖苷-(1→3)]-β-D-岩藻吡喃糖苷(2),(25R)-ruscogenin1-O-[3-O-(乙酰基)-α-L-鼠李吡喃糖苷-(1→2)][β-D-木糖吡喃糖苷-(1→3)]-β-D-岩藻吡喃糖苷(3),蜕皮甾酮(4)。所有化合物均为首次从该植物中分得。更多还原

【Abstract】 C-27 steriods were isolated on Diaion HP-20 and silica gel column chromatography and the structures were identified by spectral technologies.Four compounds from ethyl acetate extracts were elucidated as (25-R-)ophiopogonin D,(25R)-spirost-5-ene-1β,3β-diol[(25R)-ruscogenin]1-O-{O-α-L-rhamnopyranosyl-(1→2)-O-[β-D-xyloptranosyl-(1→3)]-β-D-fucopyranoside}(1),(25R)-ruscogenin 1-O-[2-O-(acetyl)-α-L-rhamnopyranosyl-(1→2)][β-D-xylopyranosyl-(1→3)]-β-D-fucopyranoside (2),(25R)-ruscogenin 1-O-[3-O-(acetyl)-α-L-rhamnopyranosyl-(1→2)][β-D-xylopyranosyl-(1→3)]-β-D-fucopyranoside (3),ecdysterone(4).All of these compounds were first isolated from Sagina japonica.更多还原
