Objective : To contrast preparation technology of the Shuangbai spray and Shuangbai film spraying agent. Method: Adopted water extraction and alcohol sink method to produce Shuangbai spray and adopted ethanol extraction method to produce Shuangbai film spraying agent

compared dosage of medicinal materials

the content of index components and transfer rate

film performance. Result: In Shuangbai spray

dosage of medicinal materials was 1 001 g and the content of the Emodin was 82.70 mg with it's transfer rate was 8.63%

and the content of hydrochloride berberine was 97.61 mg with it's transfer rate was 6.63%. It couldn't become film when Shuangbai spray was sprayed onto skin. But in Shuangbai film spraying agent

dosage medicinal materials was 140 g and the content of emodin was 99.67 mg with it's transfer rate was 74.38%

and the content of hydrochloride berberine was 113.79 mg with it's transfer rate was 55.24%. It could become film with a good performance in five minutes when Shuangbai film spraying agent was sprayed onto the skin. Conclusion: Preparation technology of Shuangbai film spraying agent was simple

improved utilization rate of medicinal materials

had good film performance

and better than preparation technology of Shuangbai spray.
