摘　　要：为建立渝产续断(Dipsacus asperoids)多糖的最佳超声波辅助提取工艺,设计正交试验,以续断多糖的提取率为评价指标,对续断多糖的超声波辅助提取工艺参数进行考察。结果表明,最佳超声波辅助提取工艺为料液比1∶20(g∶m L),提取时间60 min,提取4次,测得续断多糖的平均提取率为7.472%,RSD为2.12%,表明续断多糖超声波辅助提取工艺稳定,质量可控。To establish the optimal microwave-ultrasonic assisted technology of extracting polysaccharides from Dipsacus asperoids in Chongqing city, orthogonal experiment was conducted. The extraction percentage of polysaccharides was used as an evaluation index to screen the parameters of the microwave-ultrasonic assisted technology of extracti ng polysaccharides from Dipsacus L.. The ratio of materials to liquids was 1∶20（g∶m L）, with 4 times of 2 h. The average extraction rate was 7.472%.RSD was 2.12%. The extraction was stable with controllable quality.
