摘要
利用正交试验确定了破铜钱中总黄酮的最佳提取条件并测定了其含量。结果表明,用50%乙醇溶液,提取温度80℃,料液比1∶30,提取时间1h,提取效率较好,总黄酮得率为2.67%。
The optimal extraction conditions of total flavonoid from Hydrocotyle sibthorpioides var were obtained by orthogonal test. The content of total flavonoid was determined by UV method. The results showed that the yield of total flavonoid was 2.67 % at the conditions of 50 % ethanol solution, 80 ℃, 1 ： 30 solid-liquid ratio and 1 h for extraction.
