Abstract

Objective:To establish a HPLC method of the determination of the przewatanshinquinone in Tongmailing tabeles. Methods: The determination was performed by Re-HPLC on Kromasil^TM C₁₈ column（200 mm×4.6 mm,5μm）using methanol-toni- trile-0.045 mol/L H₃ PO₄（10:4:86）as mobile phase,the detection wavelength was 281 nm. Results: The linear rang of przewatan- shinquinone was 0.194～2.129μg,r=0.999 8.The average recovery was 99.56%,RSD was 0.84%（n=5）. Conclusion: The method is sensitive,simple,and good reproducibility,which can be applied to the quality control of the preparation.
