摘要 以刺梨为原料,采用微波辅助超声法提取刺梨中的总皂苷。在单因素试验基础上,根据中心组合试验设计(CCD)原理,以总皂苷得率为考察指标,对提取工艺条件进行响应面试验设计优化。结果表明,微波辅助超声法提取刺梨总皂苷最佳工艺条件为:乙醇体积分数54%、液料比15∶1(m L∶g)、微波功率545W、超声时间22 min。在此优化工艺条件下,刺梨总皂苷得率实际值为4.18%,与理论值之间的相对误差为0.7%,充分说明了试验所建立模型的稳定性和可靠性。 Using Rosa roxburghii (Thorn pear) as raw material, the total saponins in R. roxburghii was extracted by microwave-assisted ultrasonic method. According to the principle of central composite design (CCD), using the extraction rate of total saponins as evaluation index, the extraction technology conditions were optimized by response surface methodology based on the single factor experiments. The results showed that the optimum technology conditions for the extraction of total saponins from R. roxburghii by microwave-assisted ultrasonic method were as follows: ethanol volume fraction 54%, liquid to material ratio 15∶1 (ml∶g), microwave power 545 W and ultrasonic time 22 min. Under the optimal condition, the actual extraction rate of total saponins was 4.18%, and the relative error between the actual and theoretical value was 0.7%, which verified the stability and reliability of the model established by the experiment.
