【摘要】 目的 :改进银翘解毒合剂中银花的提取工艺。方法 :用 3种不同的提取方法 ,不同的乙醇浓度 ,不同的回流时间 ,采取 L9(33)因素水平设计正交试验 ,优选银花有效成分的提取工艺。结果 :银花的最佳提取工艺为 A2 B2 C1 ,即回流二次、4h、12倍量 70 %乙醇。结论 :新工艺绿原酸转化率 (72 .1～ 73.4% )明显高于老工艺(34.6 % )更多还原

【Abstract】 OBJECTIVE:To improve the technology of extracting Flos lonicerae,which is used in Yinqiao Jiedu mixtures.METHODS:Using three different extracting methods according different concentrations of ethanol and different times of reflux, and designing orthogonal test according L 9(3 3)factor levels for optimum technology of extracting Flos lonicerae.RESULT:The best technology of extracting Flos lonicerae is A 2B 2C 1,that is: reflux twice,4 hours eveny time and 12 times amount 70% ethanol.CONCLUSION:The conversion rate (72.1～73.4%)of chlorogenic acid after using new technology is much higher than that of the old technology(31.6%).更多还原
