Abstract: Objective To analyze chemical constituents of Xionggui Decotion by rapid-resolution (high performance) liquid chromatography-time of flight mass spectrometry (HPLC-TOF-MS). Methods A Shelloseido column(100 mm×3.0 mm,3 μm)was used to separate.The mobile phase consisted of water containing 0.1% methane acid and acetonitrile was used as gradient elute.The flow rate was 0.4 ml/min.TOF-MS was applied for qualitative analysis under positive ion mode. Results Under LC/MS condition,47 major constituents in Xionggui Decotion were identified by time of flight mass spectrometry and structure-relevant fragment ions. Conclusion A simple and reliable method using HPLC-TOF-MS was established to identify the chemical constituents of Xionggui Decotion.-
