| 摘 要： | 分别用甲醇、乙醇、丙酮、乙酸乙酯、正丁醇、水、酸乙醇、酸水、三氯甲烷作溶剂，采用回流法、微波法、超声波法、渗漉法、煎煮法、浸提法等6种提取方法，对湖南省特有栽培品种金银花-湘宁1号绿原酸提取工艺进行了对比.结果表明，最佳提取工艺是丙酮超声，最佳提取条件是超声提取，绿原酸的得率和提取率均最高，分别为8.46％，86.5％.优选得到的提取工艺简单，时间短.

| Abstract: | To optimize the extraction process of chlorogenic acid in flos lonicerae.several extraction processes were used respectively,i.e.,the refluxing method,the microwave method,the ultrasonic method,percolation method,decocting method and leaching method.The extracting solutions are methanol,ethanol,acetone,acetic ether,normal butand,water,acid water and chloroform.The optimum technology is acetone ultrasonic method,and the optimum extraction conditions were:10 fold of acetone,extracting 1 h,3rd time respectively.The content or chlorogenic acid and extraction rate were fairly high.The extracting rate is 8.46%,and the content of chlorogenic acid is 86.5%. |
