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)。
Three compounds (1- 3) are extracted and isolated from the flowers of lonicera japonica thunh 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.
