中间锦鸡儿黄酮类成分的研究

Studies on flavonoid constituents of Caragana intermediia

摘要: 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。

Abstract: AimTo study the chemical constituents of Caragana intermedia. MethodsThe compounds were separated by chromatography methods, their structures were identified by spectral analysis. ResultsTen compounds were isolated and identified as 5,7,4′-trihydroxy-3,3′-dimethoxyflavone(1), 3,5,7,8,4′-pentahydroxy-3′-methoxyflavone(2), quercetin(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). ConclusionCompound 6 is a new compound and the others were obtained from this plant for the first time.
