中间锦鸡儿黄酮类成分的研究

目的研究中间锦鸡儿的化学成分。方法用溶剂法、色谱法分离化学成分，用波谱法鉴定其结构。结果从中间锦鸡儿中分离得到10个黄酮类化合物，分别鉴定为5,7,4′-三羟基-3,3′-二甲氧基黄酮(1)，3,5,7,8,4′-五羟基-3′-甲氧基黄酮(2),槲皮素(3),柠檬黄酮醇(4),槲皮素-3-甲醚(5)，2(S)-7,3′,5′-三羟基二氢黄酮(6)，5,7,3′,4′-四羟基-3,8-二甲氧基黄酮(7),紫铆查尔酮（8）,甘草素（9）和5,7,4′-三羟基-3,8二甲氧基黄酮（10）。结论化合物6为新化合物，其余皆首次从中间锦鸡儿中分离得到。

Studies on flavonoid constituents of Caragana intermediia

AIM: To study the chemical constituents of Caragana intermedia. METHODS: The compounds were separated by chromatography methods, their structures were identified by spectral analysis. RESULTS: Ten compounds were isolated and identified as 5,7,4'-trihydroxy-3,3'-dimethoxyflavone (1), 3,5,7,8,4'-pentahydroxy-3'-methoxyflavone(2), puercetin(3), limocitrin(4), 5,7,3',4'-tetrahydroxy-3-methoxyflavone(5), 7,3',5'-trihydroxyflavanone(6), 5,7,3',4'-tetrahydroxy-3,8-dimethoxyflavone(7), butein(8), liquiritigenin(9) and 5,7,4'-trihydroxy-3,8-dimethoxyflavone(10). CONCLUSION: Compound 6 is a new compound and the others were obtained from this plant for the first time.
