| Abstract: | OBJECTIVE To identify the active components in Venenum Bufonis by high performance liquid chromatography(HPLC)-electrospray-time of flight mass spectrometry(ESI-TOF-MS).METHODS The separation was performed on an Agilent Eclipse XDB C18(4.6 mm×150 mm,5 μm) column with gradient elution of acetonitrile and water(with 0.1% acetic acid) as mobile phase,flow-rate was 0.8 mL·min-1,with gradient elution at room temperature(about 25 ℃).The detection wavelength was 291 nm and the UV spectra of peaks were obtained with a photodiode array detector(DAD).On-line ESI-TOF-MS in positive mode was used to get the mass spectrum of some of the analytes.RESULTS 12 Effective components in Venenum Bufonis were primarily identified by comparison of the UV spectra and mass spectrum with literature and 10 were confirmed according to others' work results.CONCLUSION HPLC-ESI-TOF-MS is a very powerful tool for the identification of the effective components in Venenum Bufonis. |
