目的:研究女贞子中总黄酮的超声提取工艺.方法:以芦丁作为对照品,总黄酮提取率为指标,采用正交试验优化乙醇浓度、提取次数、超声时间、料液比对总黄酮提取率的影响.结果:所考察的因素对女贞子总黄酮的提取率影响顺序为:提取次数>超声时间>料液比>乙醇浓度,优化的提取条件:乙醇体积分数为40%、料液质量体积比1:25(g:mL),超声提取3次,每次超声处理1 h.结论:该超声提取工艺易于操作,不需加热,提取效率高,提取率为60.6 mg·g-1,即每1 g女贞子可提取60.6 mg总黄酮.
目的:研究女貞子中總黃酮的超聲提取工藝.方法:以蘆丁作為對照品,總黃酮提取率為指標,採用正交試驗優化乙醇濃度、提取次數、超聲時間、料液比對總黃酮提取率的影響.結果:所攷察的因素對女貞子總黃酮的提取率影響順序為:提取次數>超聲時間>料液比>乙醇濃度,優化的提取條件:乙醇體積分數為40%、料液質量體積比1:25(g:mL),超聲提取3次,每次超聲處理1 h.結論:該超聲提取工藝易于操作,不需加熱,提取效率高,提取率為60.6 mg·g-1,即每1 g女貞子可提取60.6 mg總黃酮.

To study ultrasonic extraction techniques of total flavonoids in Fructus ligustri. Methods:Taking Rutin as a reference and extraction ratio of total flavonoids as a index, to study how ethanol concentration, ultrasonic time, solid-liquid ratio and extraction times affect extraction ratio of total flavonoids in Fructus ligustri, by orthogonal design. Results:The results showed that the order of factors to affect total fiavonoid extraction was extraction times > ultrasonic time > solid-liquid ratio > ethanol concentration. The optimum ultrasonic extractions were:A3B1C3D2. ethanol concentration was 40%,ultrasonic time was 60 min,solid-liquid ratio was 1:25 and extraction times was 3. Conclusion:The developed techniques are easy to operate, improve extraction rates and need no heating.
