摘 要:目的:研究多刺锦鸡儿Caragana spinifera全草的化学成分。方法:采用硅胶柱色谱等方法分离化合物,采用理化性质和波谱分析法鉴定其结构。结果:分离并鉴定了6个化合物,分别为(6aR,11aR)-3-羟基-4,9.二甲氧基紫檀烷(1),(6aR,11aR)-4,9-二羟基-3-甲氧基紫檀烷(2),5,4'-二羟基-7-甲氧基异黄酮(3),7-羟基-4-甲氧基异黄酮(4),6,7-二羟基-4’-甲氧基异黄酮(5),β-谷甾醇(6)。其中化合物1的结构还得到X—ray单晶衍射的证实。结论:化合物1~6均首次从该植物中分离得到。Objective: To study the chemical constituents of the whole plant Caragana spinifera. Method: The chemical constituents were isolated and repeatedly purified on silica gel column. The structures were elucidated by the NMR spectra and physicochemical properties. Result- Six compounds were isolated and identified as ( 6aR, 11 aR ) -4, 9-dimethoxy-3-hydroxypterocarpan, ( 6aR, 11 aR) -4, 9 -dihydroxy-3- methoxypterocarpan ( melilotocarpane B ) , 5, 4'-dihydroxy-7 -methoxyisoflavone, 7-hydroxy-4'-methoxyisoflavone, 6, 7-dihydroxy-4'-methoxyisoflavone, β-sitosterol respectively. Conclusion: All compounds were isolated from the plant for the first time.
