英文摘要: The electrospray ionization tandem mass spectrometric characteristics and fragmentation mechanisms of 12 triterpenoid compounds from Fomes officinalis (F. officinalis) and their analogs were investigated. The compounds could be classified into three types depending on their chemical structures. All of the compounds gave [M - H](-) and [2M - H](-) ions by electrospray negative ionization mode. In addition, the members of three isomeric groups of the analogs with the same elemental composition can be distinguished by tandem mass spectra of protonated molecules and of significant fragmention. The above fragmentations were reported for the first time and were implemented for the analysis of triterpenoids in F. officinalis.
