摘要: 通过单因素实验和正交实验研究,超临界流体萃取蜂胶黄酮类化合物的工艺进行了优化设计。试验结果表明:影响萃取得率的各因素强烈程度顺序是:萃取压力>乙醇浓度>固液比>萃取温度;最佳萃取实验工艺条件为:萃取压力:25MPa,乙醇浓度95%,固液比:6:1,萃取温度为500C,萃取时间为4h,流体流速为35kg/h。而且黄酮类化合物得率较高、萃取物纯净、色泽金黄、纯度高。

Abstract: The supercritical fluid extraction technology of Propolis flavonoids was optimized by single-factor and orthogonalexperiments. Experimental results showed that the successive order of different effect factors on extraction rate was extrac-tion pressure>alcohol concentration>solid-liquid ratio>extraction temperature. The optimal experimental parameters were25MPa extraction pressure, 95% alcohol concentration, 6:1 solid-liquid ratio, 50℃ extraction temperature, 4h extraction timeand 35kg/h fluid velocity. The results also showed that the extraction rate of flavonoids was considerable large, and theextraction product was pure, golden in color and high in purity.
