摘　　要：应用超声法提取了紫荆花红色素。用正交实验优化了超声提取的工艺条件。结果表明,各因素对提取率的影响大小依次为:料液比>超声功率≈提取剂体积分数>提取时间;对2.000 g紫荆干花提取2次,最佳提取条件为:提取剂为85%乙醇,料液比1∶20(g∶mL),提取时间15 min,超声功率70 W。超声技术省时、高效、节能,适用紫荆花天然色素的提取。Ultrasonic method was used to extract red pigment from Cercis chinensis Bunge.. Orthogonal experiment was used to determine the optimal extraction conditions. Result showed the influential sequence was ratio of raw material to solvent 〉 ultrasonic power≈ alcohol volume fraction〉 extraction time. The optimal conditions were ratio of raw material to solvent 1 ： 20 （g： mL）, extraction time 15 min, ultrasonic power 70 W and 85 % alcohol when dry flower 2. 000 g was extracted by twice. Ultrasonic technique was time-saving, high efficient and energy-reducing,which could be used to extract natural pigment from Cercis chinensis Bunge..
