Objective:
To develop the quality control standard of Zhishidaozhi Tabloid Pills.
Method:

Result:
Radix et Rhizoma Rhei, Fructus Aurantii Immaturus, Rhizoma Coptidis and Radix Scutellariae could be indentified by TLC. Emodin showed a good linear relationship at a rang of 0.0612-0.612 microgram, r = 0.9999. The average recovery was 97.9%, and RSD was 2.1%.
Conclusion:
The methods are accurate and quick, and can be used for the quality control of Zhishidaozhi Tabloid Pills.
