摘要
目的探讨消结涂膜剂的质量控制标准。方法采用薄层色谱法对消结涂膜剂中赤芍、大黄、黄芩进行定性鉴别;双波长薄层扫描法测定连翘酚含量;其测定波长λs=440 nm,参比波长λr=700 nm。结果3批样品中连翘酚含量分别为0.168,0.181,0.175 mg.mL-1,平均回收率为101.13%,RSD1.42%。结论采用双波长薄层扫描法测定消结涂膜剂中连翘酚的含量,方法简便,快速准确。
Objective To probe into the quality standards of xiaofie paint. Methods The qualitative identification of Radix paeoniae Rubra, Rheum palmatum and Radix Scutellariae baicalensis in xiaojie paint was carried out with thin layer chromalography （TLC）. The content of forsythol was determined with dual-wavelength TLC scanning with a detection wavelength （λs） of 440 nm and a reference wavelength （λr） of 700 nm. Results The average rate of recovery of the forsythol was 101.13%, with an RSD of 1.42%. Conclusion The method for the determination of the content of forsythol in the xiaojie paint with dual-wavelength TLC scanning was handy, quick and accurate.
