this was believed to be more likely. So, a small aliquot of each crude extract was treated with hydrogenation conditions to reduce all olefins. Subsequent GCMS analysis revealed the presence of the same two saturated amines in both derivatized crude extracts, including the known 7-(4-methylpentyl)-indolizidine ( ) and a metabolite that was 14 mass units larger (Fig. and). We suspected the larger metabolite was likely 2-(4-methylpentyl)-quinolizidine .
