【摘要】 从微波处理后中药金银花中通过溶剂提取,硅胶柱层析,SephadexLH-20柱层析和制备薄层层析等方法分离得到三个化合物,波谱分析(核磁共振氢谱、碳谱和质谱)确定它们的结构分别为槲皮素-3-O--βD-葡萄糖苷(quercetin-3-O--βD-g lucoside),绿原酸(ch lorogcn ic acid),β-谷甾醇(-βsitostero l)。更多还原

【Abstract】 Three compounds(1~ 3) are extracted and isolated from the flowers of lonicera japonica thunb by repeated chromatography.Three structures were identified by spectroscopic analysis(1HNMR,13CNMR and MS) to be quercetin-3-O-β-D-glucoside(1),chlorogcnic acid(2) and β-sitosterol(3) respectively.更多还原
