摘　　要：本文以干燥柚皮为原料,采用碱提酸沉法从柚皮中提取柚皮甙。探讨了提取柚皮甙的影响因素,确定最佳工艺条件。结果表明,碱提酸沉淀法的最佳工艺条件为:液料比为20:1(m L:g),提取时间为180 min,提取温度为60℃,碱浸p H值为13.0,酸析p H值为4.0,浓缩后体积为120 m L,柚皮甙的质量收率最高,可达4.9%。Naringin was successfully extracted from dry pomelo peel by using the alkali extraction and acidprecipitation method. To obtain the optimum extraction condition, different influencing factors for the extraction ofnaringin were investigated. Experimental results show that the highest yield of naringin was up to 4.9%. Theoptimum conditions were determined as follows： the ratio of liquid to solid being 20：1（m L：g）, extraction time of 180 min, extraction temperature of 60 ℃, alkali leaching p H being 13.0, acid precipitation p H being 4.0, volume ofconcentrated liquid of 120 m L.
