Four major fragment ions of carboxide (CO), carboxylation (C[O.sub.2]), aldehyde (CHO), and hydroxide (OH) could be speculated, according to the mass losses of 28 Da at m/z 152.0 and 124.1, 44 Da at m/z 135.9, and 29 Da and 17 Da at m/z 107.3.
Because of the mass losses of (-28) and (-18) detected in the [MS.sup.2] fragmentation spectrum of ions at m/z 145.9, this metabolite might be derived from the carboxide and hydroxyl additions.
