Title: $Determination of the Fingerprint Chromatogram of Qingkailing Injection by HPLC
Abstract: Objective:To establish the fingerprint chromatogram of qingkailing injection.Methods:HPLC with NUDEOSIL-C18 column was used,the(a)methanol,(b)0.5%acetate buffies as a mobile phase and detection wavelength at 255nm.Results:17 peaks were indicated on the HPLC-fingerprint of qinLgkailing injection.the relative retention time and relative peak area were obtained with itself peak.Conclusion:Perfect fingerprims were obtained which can be used for the quality control of qingailing injection.
