摘　　要：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 .
