摘　　要：采用响应面分析法,以紫背天葵中紫色素含量为指标,考察超声时间、料液比、提取次数等因素对紫背天葵紫色素含量测定的影响,优选三峡库区紫背天葵紫色素的提取工艺条件。优选出三峡库区紫背天葵紫色素的最佳工艺为超声时间为15min,提取2次,料液比1∶20(g/mL),该条件下三峡库区紫背天葵紫色素的含量为2.783mg/g鲜重。The text has Optimization about extraction conditions of purple pigment extraction in Begonia imbristipula Hance of the Three Gorges Reservoir area by response surface analysis, the factors contain ultrasonic time, ratio of material to liquid, extract times . The best process in Three Gorges Reservoir area of Begonia fimbristipula Hance purple pigment as the ultrasonic time of 15 minutes, the ratio of material to liquid is 1 ： 20, extracting 2 times, the contents of Begonia fimbristipula Hance purple pigment under the conditions of 2.783 mg/g fresh weight.
