摘　　要：以海红果干粉为原料,探讨了微波辅助乙醇提取海红果中白藜芦醇的工艺,采用比色法进行白藜芦醇的含量检测。通过单因素及正交试验的优化,结果得出:微波法提取的最优条件为微波功率360 W,微波时间120 s,提取料液比为1g∶25m L、提取剂体积浓度80%。在此条件下,白藜芦醇的平均提取率高达97.06μg/g。The dry powder of circassian fruit was used as test material, to study the microwave-assisted extraction process of resveratrol in it, and the content of resverstrol was tested by colorimetric method. Through single-factor and orthogonal experiment optimization, the results concluded that the suitable extraction conditions of microwave power was360 W, microwave radiation time was 120 s, the additive volume of solvent was 1：25, the volume fraction of solvent was80%. Under the optimal condition, the rate ofresveratrol could be reached 97.06 μg/g.
