摘要
采用响应面设计法(RSM)优化水溶性龙胆多糖的提取条件。在单因素试验基础上,结合响应面法优化确定提取水溶性龙胆多糖的最适工艺条件如下:提取温度100℃,料液比1∶26.56(g/mL),提取时间3 h,提取次数2次。此条件下,水溶性龙胆多糖的提取率预测值为13.51%,水溶性龙胆多糖的试验提取率为(13.36±0.25)%,预测值与验证值吻合较好。
Response surface methodology （RSM） was used to optimize the extraction conditions of water-solubility polysaccharides from the Gentiana scabra Bunge （GSP）. Combining single factor test and response surface methodology, the optimum extraction conditions were chosen as follows：extraction temperature was 100℃, ratio of water to raw material was 26.56, extraction time was 3 h, and number of extraction was 2. Under the optimize conditions, the predicted value of yield of GSP was 13.51%, and the experimental yield of GSP was（13.36± 0.25）%, which showed the results were reasonable.
