The mass spectra of 53 alkaloids and their derivatives are considered. It is known that the presence of a C6(OCH3)-C7(OH)-C8 (OH) grouping in C19-diterpene alkaloids leads to a high intensity of the (M - 15)+ ions at the expense of the C6(OCH3) group

The new C18 diterpene alkaloids monticamine and monticamine have been isolated from the epigeal part ofAconitum monticola Steinb. Their structures have been established on the basis of the results of1H and13C NMR, IR, and mass spectra and also of che

The epigeal part ofAconitum monticola Steinb. has yielded two C18 diterpene alkaloids which, on the basis of the results of a study of NMR, IR, and mass spectra, and also of chemical transitions, have been shown to be identical with synthetic deoxyde
