摘　　要：以金银花为原料,采用醇提水沉法提取绿原酸,考察乙醇浓度、料液比、浸提时间和浸提温度对绿原酸提取率的影响。采用正交试验对工艺条件进行了优化研究,结果表明最佳工艺条件为:乙醇浓度60%、料液比1∶25、浸提时间60min、浸提温度60℃。在最佳工艺条件下进行提取,提取率为4.63mg/g。Chlorogenic acid was extracted from honeysuckle by ethanol extraction and water sedimentation, and the effects of ethanol concentration, solid-liquid ratio, extraction time and temperature on extraction rate were investigated. The extraction technology was optimized by orthogonal tests. The results showed the optimum extraction parameters as follows： ethanol concentration 60%, solid-liquid ratio 1 ： 25, extraction time 60 min and extraction temperature 60℃. The extraction rate of chlorogenic acid was 4.63 mg/g under the optimal conditions.
