以大黄素含量为指标对虎杖中有效成分进行了超声波-微波协同萃取。采用正交设计法优化了萃取条件。试验结果表明在超声波功率内置为50 W的仪器条件下影响大黄素萃取的主要因素依次是：乙醇浓度、提取时间、乙醇用量、微波功率。大黄素的最佳萃取条件是：乙醇浓度为90%,乙醇用量为75 mL,提取时间为5 min,微波功率为30 W。正交优化条件下,大黄素得率可达1.26%。萃取效果明显优于传统的溶剂回流方法和超临界流体萃取。

Experiments were studied on extraction of effective components of polygonum cuspidatum sieb. Et. Zucc by ultrasonic cooperate with microwave with the reference of emodin. The optimum synergistic extraction conditions for emodin were determined by orthogonal design. The results showed that the optimum extraction conditions were as following： concentration of alcohol 90%, volume of alcohol 75mL, extraction time 5 minutes, power of microwave 30W, The yield of emodin by uhrasonic-microwave synergistic extraction was 1.26% which was superior to traditional solvent refluxing method and supercritical fluid extraction.
