摘　　要：目的比较不同干燥方法对祁菊中绿原酸含量的影响,为筛选祁菊无硫加工方法奠定基础。方法采用真空微波干燥、阴干、烘干、真空冷冻干燥、硫磺熏蒸等方法加工同一批新鲜祁菊花,用超声提取法提取祁菊花中的绿原酸,以HPLC测定不同干燥方法得到的祁菊中绿原酸的含量。结果五种不同干燥方法比较,真空微波干燥法(80℃,8min)干燥的祁菊花中绿原酸的含量最高,其次为硫熏、真空冷冻干燥、烘干、阴干。结论真空微波干燥法(80℃,8min)干燥的祁菊花外观性状最佳且绿原酸的含量最高,建议产地加工时推广使用。Objective This study was the fundamental work of selecting sulfur- free processing method of Chrysanthemi Flos via compares the effect of various process methods to chlorogenic acid content. Methods One batch of fresh Chrysanthemi Flos was dried by vacuum microwave drying,shade drying,baking drying,vacuum freeze- drying and sulfur fumigation drying respectively,then used HPLC to determine the content of chlorogenic acid which was extracted by ultrasonic extraction method in Chrysanthemi Flos processed by various drying method and compared different drying methods influencing on these effective constituents.Results Chlorogenic acid content of Chrysanthemi Flos dried by vacuum microwave drying method was highest in the above dried methods,followed by sulfur fumigation drying,vacuum freeze- drying,baking drying,shade drying. Conclusion The appearance of Chrysanthemi Flos dried by vacuum microwave drying method（ 80℃,8min） was best with highest chlorogenic acid,so this method might be the best one to spread when the herbalists put into production.
