| Abstract: | Main rules of fragmentation of molecular ions of the esters of isosteviol diterpenoid (ent-16-oxobeieran-19-carboxylic acid) are established. It is shown that under the conditions of electron impact in the isosteviol
esters the ester C-O and C4-C19 bonds are ruptured. During the fragmentation of hydroxy derivatives of isosteviol at the C16 atom the elimination of H2O molecules is observed. |
