| Abstract: | The chlorogenic acid was extracted from Eucommia ulmoides leaves by ultrasonic assisted technique,and the effects of different extraction conditions on the extraction rate of chlorogenic acid were studied.The results showed that the optimum extraction conditions of chlorogenic acid from Eucommia ulmoides leaves by response surface methodology were as follows:the ratio of liquor to material 16∶1(mL/g),ethanol concentration 50%,extraction time 20 min,solvent pH 5,and leaching times 3 times.Under these conditions,the extraction rate of chlorogenic acid was 6.338%. |
