以干燥菊花为原料，以菊花中总黄酮提取率为指标，在单因素实验基础上，采用微波辅助提取菊花中总黄酮，确定菊花中总黄酮提取的最佳工艺条件，并对提取工艺进行了优化。结果表明微波辅助提取最佳工艺条件为：乙醇质量分数70%，料液比1：30，微波辐射时间2 min，辐射温度60℃，此时总黄酮提取率为8.479%。%The optimal condition for extracting flavonoids from chrysanthemum was investigated via mi-crowave-assisted extraction technology using the extraction rate of flavonoids as an indicator on the basis of single factor experiment. The results showed that the extraction rate was up to 8.479% under the opti-mum extraction condition, e.g. mass percentage of ethanol 70%, material-to-liquid ratio of 1:30, mi-crowave radiation time of 30 min and radiation temperature 50.
