摘　　要：目的 :通过对微波预处理过程以及热水洗涤过程的影响因素分析 ,得到最佳提取工艺参数。方法 :用 75 %乙醇溶液湿润干金银花 ,然后在微波加热下快速汽化进行预处理 ,最后再用热水洗涤两次 ,每次 10min。并与传统的提取方法相比。结果 :微波预处理提取法的提取时间缩短 6倍、提取率提高 1%。结论 :该法提取率高 ,提取时间短。Objective:The best operation condition of extraction was found through analyzing the influences of both process of microwave pretreatment and hot wave washing. Methods: A new extraction method of chlorogenic acid was that the dry FLos Lonicerae was humidified with 75% ethanol-water solution at first, then the wet Flos Lonicerae was rapidly vaporized by microwave heating, at last chlorogenic acid was extracted after hot water washed twice, 10 minutes each time. Results: Compared with traditional extraction, the extraction time was about less than 6 times and then extraction ratio was increased by 1%. Conclusion: The method has high rate of extraction and short time of extraction.
