正交试验法优选菟丝子总黄酮提取工艺

Orthogonal Test for the Effect of Alcohol Extracting Process to Total Flavones Contents from Cuscuta Seeds

用正交实验法对菟丝子中总黄酮的提取工艺进行了探讨。实验确定的最佳提取条件为：用８倍量９５％乙醇回流提取６ｈ。

Concentration of alcohol, reflowing time and amount of alcohol were tested in orthogonal analysis for alcohol extracting process. Experimental results showed that concentration of alcohol was the significant fact to total flavone content with P<0.05. The best extracting process can be described as: the drug powder is reflowed 2 times, 3hrs each, 95% alcohol with 8 times of the amount to drug weight.
