Abstract:
Objective To establish the quality standard for Ziyin Mingmu tablets. Methods TLC method was used to identify Moutan Cortex, Corni Fructus, Notopterygii Rhizoma et Radix and Acori Tatarinowii Rhizoma. HPLC method was used to determine the content of Salvianolic acid B. Kromasil ODS column (250 mm×4.6 mm, 5μm) was adopted by using MeOH-acetonitrile-1.67%methanonic acid water solution (24∶10∶66) as the mobile phase. The detection wavelength was at 284 nm, column temperature was at 30℃, and the flow rate was 1.0 mL/min. Results The TLC spots were clear without interference of the negative control. The linear range of Salvianolic acid B was within 0.32-1.92 μg (r=0.999 9). The average recovery was 99.91% (RSD=0.63%). Conclusion The method is specific, reproducible and accurate, and can be used for the quality control of Ziyin Mingmu tablets.
