摘要
以榴莲果皮为原料,微波技术耦合乙醇-硫酸铵双水相体系提取榴莲皮中的黄酮。考察了单因素乙醇浓度、料液比、微波功率、提取时间、硫酸铵的用量对黄酮提取率的影响。在微波功率250 W条件下,采用正交试验确定了最优提取条件为:乙醇浓度为60%、提取时间为120 s、料液比为1:60、硫酸铵用量为0.05 g/mL,在最优条件下总黄酮提取率可达到4.842%。
With the durian peel as raw material, the flavonoid was extracted from the durian peel by maicrowave-assisted aqueous two-phase system. The effect of the conditions, such as the ethanol concentration, the solid-liquid ratio, the microwave power, the extraction time, and the amount of the ammonium sulfate, on the extraction rate of the flavonoid were studied. Under the condition of microwave power 250 W, the optimum extraction conditions which was the ethanol concentration 60%, the extraction time 120 s, the solid-liquid ratio 1：60, and the amount of the ammonium sulfate 0.05 g/mL were got by the orthogonal test. At the optimum conditions, the extraction rate of the flavonoid could reach 4.842%.
