title: Aporphines. 25-trimethylislyl derivatives of N-methyl and N-propyl aporphines: gas chromatographic and mass spectrometric properties.
abstract: A series of synthetic, semisynthetic and naturally occurring aporphine alkaloids were converted to the O-trimethylsilyl derivatives, and analyzed by gas chromatography mass spectrometry. A discussion of structurally informative fragment ions along with gas chromatographic data is presented. Their applicability to the analysis of biological metabolites of apomorphine, a CNS active structural analog of dopamine, is discussed.
