【 摘 要 】

To know the extraction effects of GBH film medicine and the influence on film quality evaluation. Ultrasonic extraction and reflux extraction were used to extract the two methods with the traditional water decocting method to contrast. They were used to determining the content of total flavonoids. The same method was used to separate the root of the main medicinal herbs and the decoction of the water decoction of the other drug powder. They were used to determine the content of total flavonoids. The effect of extraction method on the preparation of membrane was investigated. The membrane preparation, evaluation and flexibility, respectively, film-forming property, smoothness and disintegration time are used to evaluating separately the effect of extraction method. The results showed that the extraction effect of 70% ethanol concentration of total flavonoids. The best extraction method had no effect on the film quality initial evaluation. This experiment provides a method for membrane extraction agent, has a certain practical significance.
