采用超声波辅助醇提法从苔草中提取总黄酮，以正交试验确定其最佳工艺条件。结果表明：影响苔草总黄酮提取量的因素由大到小顺序依次为：超声功率、乙醇体积分数、料液比、提取时间，本试验条件下，苔草黄酮的最高提取量为18．9 mg/g，正交试验确定超声功率为162 W、超声时间25 min、料液比1∶60、乙醇体积分数70％为苔草黄酮的最佳提取工艺。

The study aimed at optimization of the technology for extraction of total flavonoids from Carex by means of uhrasonic-assisted technique .The orthogonal design was used to optimize the extracting condition . The results showed that the order of factors that had influence on the amount of total flavonoids was :ultrasonic power>ethanol concentration>ratio of solid to liquid>extraction time .Under the conditions of the experiment , the highest extraction amount of carex flavonoids was 18.9 mg/g,the optimum conditions for extraction of fla-vonoids from Carex were 162 W of ultrasonic power ,25 min of extraction time,material-liquid ratio 1∶60,and 70%of ethanol concentration .
