[摘要]
目的对百合科植物川贝母Fritillariacirrhosa的干燥鳞茎进行化学成分研究。方法采用反复硅胶柱色谱进行分离纯化，根据理化性质和波谱数据鉴定化合物的结构。结果分离鉴定了8个生物碱类化合物，分别为川贝酮(chuanbeinone，Ⅰ)、梭砂贝母酮(delavinone，Ⅱ)、贝母乙素(pei minine，Ⅲ)、西贝素(i mperialine，Ⅳ)、petil-idine(Ⅴ)、贝母甲素(pei mine，Ⅵ)、贝母辛(pei misine，Ⅶ)、solanidine3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-gluco-pyranosyl-(1→4)]-β-D-glucopyranoside(Ⅷ)。结论化合物Ⅰ、Ⅱ、Ⅳ、Ⅴ、Ⅷ为首次从本植物中分离得到。
