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。
採用響應麵設計法（RSM）優化水溶性龍膽多糖的提取條件。在單因素試驗基礎上，結閤響應麵法優化確定提取水溶性龍膽多糖的最適工藝條件如下：提取溫度100℃，料液比1∶26.56（g/mL），提取時間3 h，提取次數2次。此條件下，水溶性龍膽多糖的提取率預測值為13.51%，水溶性龍膽多糖的試驗提取率為（13.36±0.25）%，預測值與驗證值吻閤較好。

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.
