Abstract:In this study, single factor experiment was used to optimize the main factors of microwave-assisted extraction for paeoniflorin and paeonol from tree peony seed coats. The optimum extraction conditions were as follows: ethanol extract fraction was 70%, liquid-solid ratio was 10∶1, microwave power was 230 W, microwave time was 10 min, soaking time was 1 h and extraction times was one. Under these conditions, the yields of paeoniflorin and paeonol were 2.88 and 0.52 mg·g-1, respectively. Meanwhile, the proposed method was validated in stability, repeatability and recovery experiments and the proposed method was a stable and efficiency method.
