摘　　要：采用大孔吸附树脂纯化桔核中的柠檬苦素类物质,大孔树脂最适纯化条件是:上样浓度为4 mg/mL,pH为6.0,上样流速为1 BV/h;最佳洗脱剂为70%乙醇溶液,洗脱液pH值为8.0,洗脱速率为2 BV/h,洗脱体积为4 BV。纯化得到的样品柠檬苦素类物质含量为37.26%。Conditions of purification of Limonoids in Citrus seeds by macroporous resin were studied. The optimum purified conditions were as follows： the sample concemtration 4 mg/mL, pH value 6.0, and feeding rate 1 BV/h. And the optimum elution conditions were as follows： elute volume 4 BV, elute concentration 70%, elute rate 2 BV/h, pH value 8.0. The purity of the obtained limonoids was 37.26 %.
