摘　　要：利用乙醇-硫酸铵双水相体系萃取柚子皮中的黄酮类化合物,采用响应面法对提取条件进行优化。结果表明,最佳萃取条件为:硫酸铵质量分数30%,乙醇质量分数35%,液料比36∶1(mL/g),萃取温度50℃,萃取时间1.6 h。该条件下,黄酮类化合物的得率达到(48.22±3.04)mg/g。The extraction of flavonoids from pomelo peel by ethanol ammonium and sulfate aqueous two-phase system was studied.The results showed that the optimum extraction conditions were:30%ammonium sulfate,35%ethanol,36∶1 liquid-solid ratio,50℃temperature,1.6 h extraction time.Under this condition,the yield of flavonoids was(48.22±3.04)mg/g.
