Traces in brackets. aIdentified on the basis of the base peak fragment present (coniine m/z 84, γ-coniceine m/z 97, N-methylconiine m/z 98); bIdentified by comparison to known spectra ([43] Palisade Complete 600K Mass Spectral Library); cDifferent GC-MS analysis conditions; dCell lines A-C of A. gariepensis did not contain piperidine alkaloids; eCell lines D-F of A. viguieri did not contain piperidine alkaloids; fThe repeatability for coniine standard is 2.7% RSD (n = 6).
