The chemical ionization mass spectra of eight monoterpene alkaloids from the gentianine group and their derivatives were investigated. Isobutane, methanol, ammonia, methylamine, ethylenediamine, diethylamine and triethylamine were used as reactant gases. The application of this technique for investi
