摘　　要：以多糖得率为评价指标,采用响应面分析法对百合多糖的超声提取工艺进行优化,探讨了提取温度,料液比和超声提取时间对百合多糖得率的影响。结果表明超声提取百合多糖的最佳工艺条件为:提取温度70℃,料液比1:20,提取时间45 min。在最优提取条件下,百合多糖的平均得率为7.92%。The ultrasonic extraction technology of lily The influences of the extraction technologies involving lily extraction time on the polysaccharide index. The results showed that the polysaccharide was optimized with response surface analysis. granularity, extraction temperature, solid- liquid ratio and extracted yield were investigated by using optimum process conditions of ultrasonic extraction temperature 70 ℃, material liquid ratio 1 ： 20 extracting yield was 7.92%. polysaccharide yield as the evaluation extraction of lily polysaccharide were and 45 min. Under the optimum condition, lily polysaccharide
