摘 要 ：从滇重楼Paris polyphylla Sm. var. yunnanensis(Fr.)H－M．地上部分分离得到3个甾体皂甙，经光谱测定和化学降解证明其化学结构分别为：偏诺皂甙元—3 O-a-L-鼠李毗喃糖基（l→2）[a－L-鼠李吡喃糖基(l→4)]β-D-葡萄吡喃糖甙(A)；孕甾-5，16－二烯-3β-醇-20-酮，3β-O-a-L-鼠李吡喃糖基(l→2) [a－L-鼠李吡喃糖基(l→4)]-β-D-葡萄吡喃糖甙(B)；孕甾-5，16－二烯-3β-醇-20-酮，3β-O-a-L-鼠李吡喃糖基(l→2）〔a－L一鼠李毗喃糖基（1→4）－a－L-鼠李吡喃糖基(1→4)]-β-D-葡萄吡喃糖基(C)。甙A、B和C在滇重楼根中尚未发现，甙C系首次从重楼属植物中获得，而甙A具有止血的活性。
