| 摘 要： | 采用超声波提取法，研究了乙醇浓度、固液比、超声波提取时间、超声波功率4个因素对葛根（Puerariae lobata（Willd.） Ohwi）黄酮提取率的影响，并采用L8（27）正交试验确定超声波提取葛根黄酮的最优工艺。结果表明：超声波作用时间与固液比对葛根黄酮得率有显著影响（P〈0.05），并且其交互影响显著（P〈0.05）。优化的葛根黄酮提取条件为：乙醇浓度70％、料液比1：25、超声功率240W、超声时间40rain。

| Abstract: | The flavonoids were extracted from Puerariae lobata.The effects of the extraction conditions such as concentration of ethanol,ratio of Puerariae lobata to solution of ethanol,ultrasonic power and ultrasonic treatment time on extraction ratio of flavonoids were studied. The proper conditions were determined by L8(27) orthogonal design.The results showed that for ultrasonic treatment time and ratio of Puerariae lobata to solution of ethanol,the difference of the yield of flavonoids is significant (P<0.05),and... |
