Abstract: High performance liquid chromatography (HPLC)-atmospheric pressure chemical ionization-mass spectrometry (APCI-MS) was applied to analyze the triterpenoids in extracts of Ganoderma lucidum. The extraction conditions are: Hypersil C4 (4.6 mm × 150 mm) column with gradient elution with acetonitrile and water (2.0% acetic acid) as mobile phase, flow-rate 0.8 ml/min, and room temperature about 25 ℃. The detection wavelength is 253 nm and the UV spectra of peaks are obtainedwith a photodiode array detector (DAD). On-line APCI-MS in positive and negative mode was used to get the mass spectrum of the analyte. Thirty-two components of Ganoderma lucidum are primarily identified by comparison of the UV spectra and mass spectrum according to published literatures.
