    摘要:

    為研究以乙醇為溶劑超聲波輔助提取青錢柳葉總黃酮的工藝,，在單因素試驗的基礎上,，采用四因素二次回歸正交旋轉組合設計，以液料比、超聲處理時間,、超聲功率、溶劑體積分數(shù)為考察因素,，優(yōu)選了超聲波輔助提取青錢柳葉總黃酮的最佳工藝,。結果表明各因素對提取率的影響大小依次為：超聲處理時間、溶劑體積分數(shù),、液料比,、超聲功率。最佳工藝條件為液料比55mL/g,，超聲處理時間34min,，超聲功率720W，溶劑體積分數(shù)60%,，在此最佳條件下,，總黃酮的得率為86.63%，優(yōu)化工藝穩(wěn)定,，提取率也較高,，試驗驗證結果與模型預測值相符。

    Abstract:

    The supersonic assistance extraction processing of total flavonoids from Cyclocarya paliurus leaves was studied. By means of orthogonally rotational combination design with four factors (ratio of solvent to dry Cyclocarya paliurus leaves,，extraction time,，ultrasonic power and ethanol concentration) as influence factors, the optimal extraction technology was performed. The results indicated that the effect of factors on the extraction was in the order as follows, extraction time, the most important one, then ethanol concentration, ratio of solvent to dry Cyclocarya paliurus leaves, and ultrasonic power as the last one. The optimum conditions were ratio of solvent to dry Cyclocarya paliurus leaves 55mL/g, extraction time 34min, ultrasonic power 720W, and ethanol concentration 60 percent. With the optimized technology, the content of total flavonoids in the final product is 86.63 percent. In conclusion, the technology is relatively stable and reliable, and consistent with the validate experiment result.
