目的：采用Box-Benhnken响应面法优化大黄鞣质的微波提取工艺。方法在单因素试验基础上，选取超声功率、超声时间和料液比3个因素进行Box-Benhnken响应面法试验设计，对其提取工艺参数进行优化。结果由响应面预测模型得出的最优提取条件为：超声功率为480 W，超声时间为25 min，料液比为1∶17.8（w/v），经验证此条件下平均提取率为（12.72±0.25）%（n=3），与理论值较为接近。结论采用Box-Benhnken响应面法建立的大黄鞣质微波提取工艺模型提取率高，并能很好地预测试验结果。

Objective:To optimize the tannins from rhubarb ultrasonic-assisted extraction technique using Box-Benhnken response surface methodology. Methods:On the basis of single-factor experiments,the effects of ultrasonic power,ultrasonic time and solid to liquid ratio on the extraction yield of tannins from rhubarb was in?vestigated with a three-factor Box-Benhnken design. Results:By the response surface model to obtain the opti?mal extraction. Conditions:ultrasonic power was 480 w,ultrasonic time was 25 min,solid to liquid ratio was 1∶17.8(w/v). The validated experiment showed the yield of tannins from rhubarb was(12.72±0.25)%(n=3)under those conditions,Which was in consistency with the theoretic value. Conclusion Ultrasonic-assisted model of tan?nins from rhubarb established by Box-Benhnken design could precisely predict the experiment results well.
