响应面法优化微波辅助乙醇提取米团花黄色素工艺条件的研究

Study on optimization of microwave-assisted ethanol technology of yellow pigments from Leucosceptrum canum Smith by the response surface method

在单因素实验的基础上,利用响应面法对微波辅助乙醇提取米团花黄色素条件进行优化。实验得出,乙醇浓度为70%(V/V)、微波功率为350W、微波时间为80s,液固比为50∶1,米团花黄色素的提取率为95.23%,与预测值98.38%拟合性较好。

Based on single factor tests, the optimum extraction conditions of microwave-assisted ethanol technology of yellow pigments from Leucosceptrum canum Smith were obtained by the response surface method. The results showed that the optimum extraction conditions were as follows ：alcohol concentration 70% （V/V）,microwave power 350W,microwave time 80s,the predicted value of extraction efficiency of yellow pigments from Leucosceptrum canum Smith was 95.23%,and it was preferably fitting with the predictive value of 98.38%.
