Objective: To improve the quality control of Hongjingtian Injection, and establish a HPLC fingerprint method. Methods: Agilent XDB C18 (150 mm× 4.6 mm,5 μm) column was used as stationary phase. And water containing 0.07 % phosphoric acid-acetonitrile system was utilized as a mobile phase, at the flow rate of 0.8 mL·min-1. The detection wavelength was 278 nm, and the column temperature was set at 30 ℃. All the data was analyzed by fingerprint evaluation system (2004). Results: Components of Hongjingtian injection were analyzed. Six common peaks were obtained for standard fingerprint chromatography and five of them such as gallic acid, p-hydroxybenzoic acid, Tyrosol, Salidroside, p-hydroxycinnamic acid were identified by HPLC-MS and standard compounds. The similarities of nine batches sample were above 0.96. Conclusion: Our HPLC fingerprint method is accurate and reliable, and could be used for the quality control of Hongjingtian injection.
