中文摘要: 以枸杞为原料，考察超声波辅助提取中的料液比、时间、温度对枸杞多糖得率的影响，并采用响应面优化。枸杞多糖超声波辅助提取的最佳工艺条件：料液比为1∶20（g/mL），温度为70℃，提取时间20 min，理论枸杞多糖得率为3.37%，实际枸杞多糖得率为3.35%，近似率达到99.4%。枸杞多糖总抗氧化性达到10.44 U/mL，结果表明：枸杞多糖具有抗氧化作用。
Abstract:With lycium chinense as raw materials，studied the ultrasonic-assisted extraction of solid to liquid ratio，time，temperature effect on the yield of lycium barbarum polysaccharides，and the response surface optimization.The optimum technological conditions for ultrasonic-assisted extraction of lycium barbarum polysaccharides were that solid-quid ratio was 1∶20（g/mL），the temperature was 70℃，extraction time was 20 min. The theory of lycium barbarum polysaccharide was 3.37%，the actual yield of lycium barbarum polysaccharide was 3.35%，the approximate rate reached 99.4%.The total antioxidant activity of lycium barbarum polysaccharide reaches 10.44 U/mL，the results showed that，lycium barbarum polysaccharides had anti-oxidative effect.
keywords: lycium barbarum polysaccharides ultrasonic-assisted extraction response surface optimization total oxidative effect
