The essential oil of geranium Bourbon (Pelargonium sp.) from Reunion was separated into acidic/phenolic and basic fractions by acido-basic extraction, respectively. The first fraction was converted into methyl esters and ethers (phenols). The two fractions were analyzed by GC/MS on a nonpolar column. In the acidic/phenolic fraction 75 compounds were separated, of which 30 were newly identified. In the basic fraction, two new pyridines-the 2-isopropyl-4-methylpyridine, and the cis-3-(1-butenyl) pyridine-were identified among other unknown amino compounds.
