摘 要 ：以牡丹果荚为原料，采用响应面分析法对影响微波辅助提取牡丹果荚中芍药苷和丹皮酚的主要因素(料液比、微波功率、微波时间)进行优化。结果表明：微波辅助提取牡丹果荚中的芍药苷及丹皮酚的最佳提取工艺条件为：液料比10∶1、微波功率253 W、微波时间10 min，牡丹果荚芍药苷和丹皮酚的得率分别为2.92、0.91 mg·g^-1。与传统提取法相比，微波辅助提取方法不仅提取时间短，原料使用量少，而且提取率高，是一个高效的提取方法。

Abstract:In this study, the response surface methodology (RSM) was used to optimize the main factors of microwave-assisted extraction for paeoniflorin and paeonol from peony seed pods, including liquid-solid ratio, microwave power and time. The optimum extraction conditions were as follows: liquid-solid ratio was 10∶1, microwave power was 253 W, microwave time was 10 min. Under these condition, the yields of paeoniflorin and paeonol were 2.92 and 0.91 mg·g^-1, respectively. Compared with the traditional extraction method, microwaveassisted extraction method could reduce extraction time, save raw material usage and enhance extraction rate, which was an efficient extraction method.
