Objective To establish1H-NMR fingerprint of Shuganning injection and to provide reference for its quality control.Methods The 1H-NMR spectrum of the sample was collected by Noesygppr1d pulse sequence[recycle delay(RD)-90°-t1-90°-tm-90°-ACQ].The proton resonance frequency was 600.13 MHz and the measurement temperature was 298 K.The methodology was verified.Correlation method and Cosin method were used to evaluate the similarity.Results 1H-NMR fingerprint of Shuganning injection was established and 88 compounds were identified.Different batches of Shuganning injection were highly similar.Conclusion The 1H-NMR fingerprint of Shuganning is established,which provide some reference for the evaluation of the quality of Shuganning injections.
