Abstract

The mass spectral behavior of a series of 5-methylchromone glycosides isolated from two Aloe species was investigated by liquid chromatography/positive-ion electrospray (ES) mass spectrometry using collision-induced dissociation (CID) mass spectrometry. The CID mass spectra of the [M + H]+ ions show a typical fragmentation pattern reflecting the several substructures (substitution at C-7, C-9 and C-10, position and nature of the ester moiety at C-2) of the 5-methylchromone glycosides. Besides a series of known 5-methylchromone glycosides, nine new compounds of this type were identified by LC/ES-CIDMS from Aloe rubroviolacea and Aloe perryi (Aloeaceae).
