| 摘要: |
| 采用超声波提取法从沙棘果渣中提取总黄酬，以正交试验法确定了总黄酮的最佳提取工艺，并与传统热回流提取法进行了比较。结果表明，超声提取沙棘果渣总黄酮的最佳提取工艺条件为：提取液V（乙酸乙酯）：V（体积分数95％乙醇）=3：7，料液比（m/V）为1：10，在温度50 ℃下提取30 min；提取方法的比较结果表明，超声提取法优于传统热回流提取法。 |

| Abstract: |
| The ultrasonic extraction of total flanovonoids in the fruit marc of Hippophae rhamnoides L.was studied.The extraction process of total flanovonoids was optimized with orthogonal experiment,and there was a comparison between the ultrasonic method and the refluxing method.The results indicated that optimum extraction conditions were determined as follows:the mixture solution of V(ethyl acetate) and V(95%-ethanol)(3∶7) as extracting solvent,stock ratio 1∶10 (mass∶volume),temperature 50 ℃,time 30 min.And the ultrasonic method was superior to the refluxing technology. |
