铁线蕨总黄酮的超声波辅助提取

A method of extracting flavonoids from Adiantum flavonoid.

以铁线蕨总黄酮含量为指标，采用超声波辅助乙醇浸提法，优化铁线蕨黄酮的提取工艺，通过单因素实验，对乙醇提取剂浓度、超声功率、超声时间和料液比进行L9（34）正交选择实验。得出最佳提取工艺为：乙醇体积分数80％，超声功率120W，超声时间1．5h，料液比1：20（g／mL），提取液黄酮含量为5．734％。

The influence of ethanol concentration, ultrasonic wave power/duration, and material - liquid ratio on the ultrasonic wave - assisted ethanol extraction of flavonoids from adiantam capiuarisveneris was studied by L9 （ 34 ） orthogonal optimization test. 5. 734% total flavones were extracted under the optimal condition,which was 80% ethanol, 120W ultrasonic wave for 1.5 hour,and 1 g material in 20 mL liquid.
