摘要
从滇重楼（Ｐａｒｉｓｐｏｌｙｐｈｙｌｌａｖａｒ．ｙｕｎｎａｎｅｎｓｉｓ）地上部分中分离出两个新的微量的甾体皂甙ｐｏｌｙｐｈｙｌｌｏｓｉｄｅⅢ和Ⅳ，根据化学降解和光谱分析，它们的化学结构分别为２７－羟基－偏诺皂甙元－３－Ｏ－［α－Ｌ－鼠李吡喃糖基（１→２）］［α－Ｌ－鼠李吡喃糖基（１→４）－α－Ｌ鼠李吡喃糖基（１→４）］－β－Ｄ－葡萄吡喃糖甙（ｐｏｌｙｐｈｙｌｌｏｓｉｄｅⅢ），２３β，２７－二羟基－偏诺皂甙元－３－Ｏ－［α－鼠李吡喃糖（１→２）］［α－Ｌ－鼠李吡喃糖基（１→４）－α－Ｌ一鼠李吡喃糖基（１→４）］－β－Ｄ－葡萄吡喃葡萄糖甙（ｐｏｌｙｐｈｙｌｌｏｓｉｄｅⅣ）。
Two new minor steroidal saponins polyphyllosid Ⅲand Ⅳ were isolated from the aerial parts of Paris polyphylla var. yunnanensis. On the basis of chemical and spectroscopic ana-lysis, their structures were established as 27-hydroxyl-pennogenin 3-O-[α-L-rhamnopyrano-syl (1→2)][α-L-rhamnopyranosyl (1→4)-α-L-rhamnopyranosyl(1→4)]-β-D-glucopy-ranoside and 23β,27-dihydroxyl-pennogenin 3-O-[α-L-rhamnopyranosyl (1→2)][α-L-rhamnopyranosyl (1→4)-α-L-rhamnopyranosyl (1→4)]-β-D-glucopyranoside, respectively.
