Abstract: Objective To analyze chemical constituents of Scutellaria barbata D.Don by high pressure liquid chromatography-time of flight mass spectrometry (HPLC-TOF/MS). Methods A SHISEIDO CAPCELL PAK C18 (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 0.6 ml/min. TOF/MS was applied for qualitative analysis under positive ion mode. Results Under optimized condition, 15 major constituents in Scutellaria barbata D.Don 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 Scutellaria barbata D.Don.
