【Abstract】 The extraction process of chlorogenic acid from Flos Lonicerae is studied. The chlorogenic acid was extracted with ethanol solution as extractant, and the effect of different factors on the extraction rate of chlorogenic acid from Flos Lonicerae was studied. The results showed that the reflux method was the best one. Among them, the best extraction conditions of reflux method show that the volume fraction of ethanol is 55%, the ratio of material to liquid is 1∶40, the time is 60 min, the temperature is 60 ℃, and the yield of chlorogenic acid is 11.0%; the best extraction conditions of ultrasonic method are: the volume fraction of ethanol is 55%, the ratio of material to liquid is 1∶40, the time is 120 min, the temperature is 60 ℃, and the yield of chlorogenic acid is 6.23%.更多还原
