摘要: 以补骨脂素与异补骨脂素总得率为考察指标,优化超声波法提取补骨脂中活性成分的工艺。选取提取时间、液料比和超声波功率为随机因子,在单因素试验的基础上,进行3因素3水平的Box-Behnken中心组合试验设计,以补骨脂素和异补骨脂素总得率为响应值进行响应面(RSM)分析,优化超声波法提取补骨脂中活性成分提取条件。结果显示,超声波法提取补骨脂中活性成分的最佳条件为:提取时间 47.5 min,液料比5.6:1(mL:g), 提取液 20 mL,提取功率 330 W,在最佳的提取条件下,补骨脂素和异补骨脂素总得率理论值为 1.043%,验证值为 1.047%,验证值与理论值间的相对误差为 0.384%,验证值与真实值相吻合,说明响应面法优化补骨脂中活性成分超声波法提取条件可行。

Abstract: Psoralen and isopsoralen are the representative active components in Psoralea corylifolia L. The total yield of them was used as the criterion for optimization of ultrasonic extraction conditions of active components from P.corylifolia. Extracting time, liquid-solid ratio and ultrasonic power were selected as casual factors. Based on single-factor experiments, three-factor-three-level Box-Behnken central composite experiment design method was applied. Total yield of psoralen and isopsoralen was used as response values. Response surface analysis methodology (RSM) was used for analysis of the results of these experiments. The optimum conditions of ultrasonic extraction were as follows:extraction time 47.5 min, liquid-solid ratio 5.6:1 (mL:g) extracting solution 20 mL, and ultrasonic power 330 W. Under these conditions, total yield of psoralen and isopsoralen was 1.043%, validation value was 1.047%, relative error was 0.384%, which demonstrated the feasibility of this method.
