摘要
目的:研究宽苞水柏枝的化学成分。方法:色谱等方法分离纯化,理化性质和光谱分析法鉴定化学成分。结果:分离并鉴定了11个化合物,分别为3,5,3′,4′-四羟基-7-甲氧基黄酮(1),3,5,4′-三羟基-7,3′-二甲氧基黄酮(2),3,5,4′-三羟基-7-甲氧基黄酮(3),槲皮苷(4),山柰酚(5),槲皮素(6),柯伊利素(7),没食子酸(8),没食子酸乙脂(9),β-谷甾醇(10),胡萝卜苷(11)。结论:上述化合物均为首次从该植物中分得。
Objective： To study the chemical constituents of Myricaria bracteata. Method： The chemical constituents were isolated by silica gel column chromatography and the structures were elucidated by spectroscopic methods. Result： Eleven compounds were obtained and identified as rhamnetin, 3, 5, 4＇-trihydroxy-7, 3＇-dimethoxyflavone, 3, 5, 4＇-trihydroxy-7-methoxyflavone, quercetin-3-O-α-L-rhamnopyranoside, kaempferol, quercetin, chrysoerio, gallic acid, gallic acid ethylester, β-sitosterol, dsucosterol. Conclusion： All compounds were obtained from M. bracteata for the first time.
