| Abstract: |
| Objective:To identify the chemical components in traditional Chinese herbal medicine Ginseng by high performance liquid chromatography diode array detector (HPLC-DAD) and High performance liquid chromatography-time of flight mass spectrometry (HPLC-TOF/MS).Methods: An Agilent Zorbax XDB-Cl8 column (250 mm×4.6 mm,5 μm) was used for isolation and identification of chemical components in Ginseng with a mobile phase of acetonitrile and water in gradient elution.A gradient program was used as follows:1-35 min,19% A; 35-55 min,19%-29% A; 55-70 min,29% A; 70-110 min,29%-40% A; 110-150 min,95% A.The flow rate was set at 1.0 ml/min,the injection volume was 20 μl,and the column temperature was set at 20℃.The time-of-flight mass spectrometer was equipped with an EIS ion source.Scanning mass range was between m/z 100-1 350.Results: Thirty-nine chemical compounds in Ginseng were identified unequivocally.Conclusion: Chromatographic demonstration of 39 chemical compounds of Ginseng in one run is achieved by HPLC-TOF/MS,which provides a foundation for further study on the metabolism and action mechanism of traditional Chinese herbal medicine. |
