【摘要】 目的 :对金银花的提取工艺进行改进 ,以提高得率及降低溶剂消耗量。方法 :首先用少量乙醇水溶液润湿金银花 ,然后加沸腾热水搅拌提取。结果 :绿原酸得率为 7.89% ,浸膏中绿原酸含量为 16 .7% ,均高于传统醇提及水提 ,但乙醇用量仅为醇提的 6 %。结论 :新工艺对绿原酸的提取具有较大的应用价值。更多还原

【Abstract】 Objective:In order to raise extract ion ratio and reduce solvent waste, the extraction technology of Flos Lonicerae was improved. Methods:First, the Flos Lonicerae was humidified with litt le ethanol-water solution, and then the chlorogenic acid was extracted by boilli ng water with whisk. Results:The extraction ratio of chlorogenic acid was 7.8 9 %. The content of chlorogenic acid was 16.7% in extract. These results were h igher than those of traditional extraction methods, but the wastage of ethanol o nly was 6% of extracting with ethanol. Conclusion:The new technology has available value in extra ction of chlorogenic acid.更多还原
