摘要: 采用响应面法优化超声波提取海南产神秘果叶总三萜的最佳工艺条件。在单因素试验的基础上,选取乙醇体积分数、提取温度、液料比和超声波作用时间作为影响因子,根据Box-Behnken中心组合原理设计4因素3水平试验,以神秘果叶总三萜的得率为响应值进行响应面分析。得到超声波提取神秘果叶总三萜的最优工艺条件为:1.0 g 神秘果叶, 乙醇体积分数 70%,提取温度 50 ℃,液料比30:1(mL:g)和超声波作用时间 33 min,实际得率 0.92%,与模型预测值(0.94%)基本相符。

Abstract: The ultrasound extraction process parameters of total triterpenoids from Synsepalum dulcificum leaf from Hainan province was optimized by response surface methodology. The experiments were arranged according to Box-Behnken central composite experiment design. Four independent influencing factors of extraction, such as concentration of ethanol, extraction temperature, the ratio of liquid to solid and ultrasonic time, were considered on the basis of single factor experiments. The results showed that the optimum ultrasound extraction conditions for total triterpenoids were as follows: concentration of ethanol 70%, extraction temperature 50 ℃, the ratio of liquid to solid 30:1(mL:g) and ultrasonic time 33 min. The experimental yield (0.92%) was in good agreement with its predicted value (0.94%) by model.
