目的：研究小叶锦鸡儿的化学成分。方法：用各种现代色谱方法分离小叶锦鸡儿根的化学成分,根据理化性质及波谱手段(MS,NMR,DEPT,¹H-¹H COSY,HSQC)鉴定结构。结果：从小叶锦鸡儿根的醋酸乙酯部分分离并鉴定了8个单体化合物,分别为β-谷甾醇(1),7-羟基-3′,4′-二甲氧基异黄酮,即赝靛黄素(2),阿魏酸二十五烷醇酯(3),阿魏酸十七烷醇酯(4),阿魏酸(5),胡萝卜苷(6),高丽槐树-7-O-β-D-吡喃葡萄糖苷(7),芒柄花素-7-O-β-D-吡喃葡萄糖苷(8)。结论：化合物1,3～7首次从该植物中分离得到,其中化合物3,4,5,7首次从锦鸡儿属植物中分离得到。

Studies on chemical constituents from roots of Caragana microphylla

OBJECTIVE: To study the chemical constituents in roots of Caragana microphylla. METHOD: The constituents were isolated by silica gel column chromatography, and their structures were identified by spectroscopic methods and chemical evidence. RESULT: Eight compounds were identified as beta-sitosterol (1), pseudobaptigenin (2), pentacosanylferulates (3), heptadecanylferulates (4), ferulic acid (5), daucosterol (6), trifolirhizin (7), ononin (8) respectively. CONCLUSION: Compounds 1, 3-7 were obtained from the plant for the first time, and 3, 4, 5 and 7 were obtained from the genus Caragana for the first time.
