摘　　要：为了优化冬瓜皮中总三萜的最佳提取工艺条件,在单因素试验基础上,选取了料液比、乙醇体积分数和提取温度为影响因子。根据Box-Behnken中心组合原理设计三因素三水平试验,以冬瓜皮中总三萜的提取量为响应值进行响应曲面分析。结果表明,冬瓜皮中总三萜提取的最佳工艺条件为料液比1∶11(g∶m L),乙醇体积分数95%,提取温度80℃,且实际提取量为3 798.63μg/g,与模型预测值(3 817.43μg/g)基本相符。In order to optimize the extraction of triterpenoids from wax gourd peel,the experiment are arranged according to Box- Behnken central composite experiment design. Three independent factors of extraction, such as the ratio of liquid to solid,concentration of ethanol and extraction temperature,are considered on the basis of single factor experiments. The results show that the optimum extraction conditions for total triterpenoids are as follows the ratio of liquid to solid 1 ∶11（g∶m L）,concentration of ethanol 95%,extracting temperature 80 ℃. The experiment value（3 798.63 μg） is in good agreement with its predicted value（3 817.43 μg） by model.
