摘　　要：开发了从柚皮中提取生物类黄酮化合物—柚皮苷的新工艺,即在常规法用饱和Ca(OH)2溶液浸提,盐酸酸析过程中,引入超声提取技术来强化浸提效果。并以精制柚皮苷收率为评价指标,利用正交设计L9(34),优选得最佳工艺条件:超声温度25℃、超声时间30min、饱和Ca(OH)2溶液与柚皮质量比4:1、超声频率25KHz。按此优选最佳工艺实验三次,精制柚皮苷平均收率达1.82%(为常规浸提法的1.58倍)。A new technology of extraction of naringin from pomelo peel was explored on normal method of extraction by saturated Ca（OH）z solution with the application of ultrasonic reactor. Naringin yield as the main evaluation indicators, and the best technical conditions were obtained through orthogonal design L9 （3^4）： extraction temperature was 25℃, extraction time was 30 min, the weight ratio of saturated Ca（OH）z solution and pomelo peel was 4：1, and the frequency of ultrasonic reactor is 25 KHz. The average yield of naringin are 1.82% in triple experiments （1.58 times more than normal extraction method）.
