There are no [M+H]^+ peaks of both KP-CD and CD in their spectra due to the samples involatile and thermal instable. A base peak at m/z 255 in the spectra of both KP and KP-CD was found, which can be assigned to [M+H]^+of KP or inclusive KP (KPi). Three fragment ions a, b and c were formed in the spectra of both KP and KPi with different abundances for the same ions. All the fragment ions of CD and inclusive CD (CDi) have been assigned.展开更多
