| 摘 要： | 采用超声波法和微波法分别对马齿苋中总黄酮的提取工艺进行了研究和对比分析.结果表明,超声波辅助萃取马齿苋黄酮的最佳工艺为料液比为1∶30,乙醇浓度为80％vol,作用温度为70℃,时间为30min,总黄酮萃取率为6.58％.微波辅助萃取马齿苋黄酮的最佳工艺为乙醇浓度为70％vol,微波功率为600W,作用时间为20min,料液比为1∶30,总黄酮萃取率7.65％.综合分析,在提取马齿苋中总黄酮的试验中,微波法萃取优于超声波法.

| Abstract: | The extraction technology of flavonoids from Portulaca oleracea L. by ultrasonic method and microwave method were studied and comparatively analysed. The results showed that the optimum ultrasonic extraction conditions were the ratio of material to alcohol solvent （80%vol） 1： 30, extraction temperature 70℃ and extraction time 30min and yield of flavonoids was 6.58% under the optimum conditions; and for microwave method, the optimum conditions were the microwave power 600W, extraction time 30min and the ratios of material to alcohol solvent （70%vol） 1： 30, and the yield of flavonoids was 7.65%. The results indicated that microwave method was better than ultrasonic method. |
