Objective To establish a specific, reliable and accurate quality control method to improve the quality standard of Anwei Granules. Methods The chromatography system, temperature and humidity of different reagents were investigated by silica gel thin layer chromatography (TLC) to optimize the thin layer identification of Coptidis rhizoma, Radix salviae miltiorrhizae and Linderae Radix. The content of total alkaloids in the preparation was determined by UV-Vis. Results The development system of Coptidis rhizoma was determined to be n-butanol-acetic acid-water (7 : 2.5 : 2), the development system of Radix salviae miltiorrhizae was toluene-trichloromethane-ethyl acetate-methanol-formic acid$\left({2 : 3 : 4 :{0.5}: 2}\right)$, and the development system of Linderae Radix was trichloromethane-ethyl acetate-formic acid$\left({4 : 3 :{0.2}}\right)$. The negative results of the three drugs were not interfered. The total alkaloid content was${4.8328}\mathrm{{mg}}/\mathrm{g}$and RSD% was 1.83% by UV-Vis assay. Conclusion In this study, an effective method for improving the quality standard of Anwei Granules was established, which has the characteristics of good repeatability and strong specificity.
