Chemical-ionization mass spectra of diterpene alkaloids

Autor: E. G. Mil'grom, V. N. Plugar, Ya. V. Rashkes

Publikováno v: Chemistry of Natural Compounds. 31:91-97

The chemical-ionization spectra of diterpene alkaloids have been investigated for the first time with the recording of positive and negative ions [Cl(+) and (−)). A comparison has been made of the CI(+) spectra with the EI and SIMS spectra. It has

Mass spectra of pseudoguaianolides related to carpesiolin

Autor: A. Ovezdurdyev, Ya. V. Rashkes, I. D. Sham'yanov, V. N. Plugar

Publikováno v: Chemistry of Natural Compounds. 29:462-466

The main directions of fragmentation and the EI of six pseudoguaianolides related to carpesiolin have been studied. It has been established that acylation of the OH group at C-6 suppresses the selective breakdown of the guaiane skeleton, while the si
