Studies on correlation for fingerprint of Yanhuanglian injections,Yanhuanglian and its extracts

Objective:Studies on correlation of fingerprint between Yanhuanglian injection,Yanhuanglian and its extracts,to establish the fingerprint detecting standard of Yanhuanglian injection.Method:Chromatographic condi- tion included a Shim-pack CLC-ODS(150 mm×6.0 mm,5 μm)column and the gradient elution was adopted with acetonitrile-buffer solution,the detection wavelength was at 285 nm and the flow rate was 1.0 mL.Use simil- arty evaluation system for chromatographic fingerprint of TCM to evaluate.Results:Correlation was good between Yanhuanglian injection and Yanhuanglian,either its extracts.Conclusion:This study is useful for establish HPLC fingerprint of Yanhuanglian injection.
