Objective: To develop a method of quality control for Hugan qingzhi tablets.
Methods: Fructus Crataegi, Rhizoma Alismatis and Radix Notoginseng were identified by TLC. HPLC was used for the determination of ursolic acid in Hugan qingzhi tablets.
Results: The chromatographic spots were identified without the interference of negative control. Ursolic acid had a good linearity over the concentration range of 40-200 microg/mL (r = 1.000). The average recoveries was 99.05% with relatively standard deviations of 1.3%.
Conclusion: This method is reliable, accurate and specific and can be used for the quality control of Hugan qingzhi tablets.
