Study on quality standard for Yejuhua Granules / 中成药

Objective: To establish the qualitative and quantitative standards for Yejuhua Granules (Flos Chrysanthemi Indici). Methods: The identification was carried out by TLC. Chlorogenic acid in preparation was determined by HPLC. The HPLC conditions were:Hypersil column (4.6nm?250 nm 5?L), mobile phase of acetonitrile-0.04% phosphoric acid solution (13∶87). Results: TLC method for the identification of Yejuhua Granules was specific. HPLC for the determination of chlorogenic acid in preparation was simple and quick, accurate and reliable. Conclusion: These methods can be used for the quality control of Yejuhua Granules.
