摘要
从滇重楼ParispolyphyllaSm.var.yunnanensis(Fr.)H-M,地上部分,分离出4个微量的配糖体,经光谱分析和化学降解证明其化学结构分别为25S-异钮替皂甙元-3-O-α-L-鼠李吡喃糖基(1→2)[α-L-鼠李吡喃糖基(1→4)]-β-D-葡萄吡喃甙(A),26-β-D-葡萄吡喃糖基-纽替皂甙元-3-O-α-L-鼠李吡喃糖基(1→2)[α-L-鼠李吡喃糖基(1→4)-β-D-葡萄吡喃糖甙(B),山奈酚-3-O-β-D-葡萄吡喃糖基(1→6)-β-D-葡萄吡喃甙(C),7-O-α-L-鼠李吡喃糖基-山奈酚-3-O-β-D-葡萄吡喃糖基(1→6)-β-D-葡萄糖甙(D)。
Isolationn and structural elucidation of four glycosides(A-D)from the aerial parts of Paris polyphylla var.yunnanensis (Fr.)H- M. On the basis of spectroscopic and chemical evidences,the structures of four glycosides were established as 25S-isonuatigenin-3- O-α-L- rhamnopyranosyl(1→2)[α-L-rhamnopyranosyl(1→4)]-β-D-glucopyranoside(A),26-O-β- D-glucopyranosyl-nuatigenin-3-O-α-L-rhamnopyranosyl(1→2)[α-L-rhamnopyranosyl(1→ 4)]-β-D-glucopyranoside(B),kaempferol-3-O-β-D-glucopyranosyl(1→6)-β-D-gluco- pyranoside(C),7-O-α-L-rhamnopyranosyl-kaempferol-3-O-β-D-glucopyranosyl(1→ 6)-β-D-glucopyranoside(D).
