Chemical-ionization Mass Spectra of Diterpene Alkaloids
Chemistry of natural compounds(1995)
摘要
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 been shown that the nature of the CI(+) and (−) spectra depends greatly on the type and position of substituents in the lycoctonine skeleton.
