摘　　要：为了解大花美人蕉(Canna generalis)的化学成分,从其根的乙醇提取物中分离得到8个化合物。通过波谱数据分析,分别鉴定为去氢催吐萝芙木醇(1)、3,4-二羟基苯甲酸乙酯(2)、咖啡酸乙酯(3)、豆甾-4,22-二烯-3,6-二酮(4)、豆甾-4-烯-3,6-二酮(5)、豆甾烷-3,6-二酮(6)、β-谷甾醇(7)和豆甾醇(8)。上述化合物均为首次从该植物中分离得到。In order to understand the chemical constituents of Canna generalis,eight compounds were obtained from its roots.On the basis of spectral data,their structures were identified as dehydrovomifoliol(1),3,4-dihydroxybenzoic acid ethyl ester(2),caffeic acid ethyl ester(3),stigmast-4,22-dien-3,6-dione(4),stigmast-4-ene-3,6-dione(5),stigmastane-3,6-dione(6),β-sitosterol(7)and stigmasterol(8).All the compounds were reported from Canna generalis for the first time.
