Abstract
Fragmentation under electron impact of eleven C18-diterpene alkaloids with an oxygen function at C-4 has been investigated. The contributions of various modes of forming the (M - CH3)+ ions have been determined. The mechanism of the appearance of the fragments (M - CH3)+ and (M - OCH3)+ at the expense of the methoxy groups at C-14 and C-16 has been considered. The characteristic nature of the parameters of the metastable peaks in the transitions to these daughter ions has been shown. Minor directions of the fragmentation of 3,4-epoxy- and 4-hydroxy bases have been characterized.
