摘要: 采用超临界CO2萃取、回流提取、超声波辅助浸提三种方法提取槲寄生中的黄酮类化合物。结果表明,超声波辅助浸提法总黄酮提取率优于超临界CO2萃取法和传统的溶剂回流提取。通过正交试验,得到最佳工艺条件为乙醇体积分数80%,超声时间15min,溶剂用量40ml/g,此条件下总黄酮的提取率为1.37%。

Abstract: Three extraction methods were compared to extract flavonoids from mistletoe.The results showed that the yield of ultrasonic aided extraction was much higher than that of supercritical CO2 fluid or reflux extraction methods.Orthogonal test was used to evaluate the effects of three methods.The optimum ultrasonic extraction conditions are as follows:adding 80% ethanol,exuacting 15 rain,the ratio of solid and liquid 1:40.The extraction yield of flavonoids is 1.37%.
