Fragmentation Pathway of Acevaltrate by Electro-Spray Ionization Ion-Trap Mass Spectrometry
The fragmentation pathway of acevaltrate was investigated by electro-spray ionization ion-trap mass spectrometry．Under the positive ion mode, pseudo-molecular [M+Na]+ could be easily obtained，and fragmentation pathway presented a certain regularity. One of the major fragmentations observed in the collision induced dissociation(CID) spectrum was loss of branched-chain, and the other was that three-membered oxygen-containing rings would break into aldehyde. These results might be used to forecast the structures of irodoids.
