大花美人蕉根的化学成分研究

Chemical Constituents from Roots of Canna generalis

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。

Abstract:

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.
