Popis:	Essential oils from two samples of Lippia graveolens HBK (South American or Mexican oregano, common in El Salvador), were obtained by hydrodistillation and studied by GC and GC–MS. Forty-five compounds, constituting 92–93% of the oil, were identified. The two major components in both samples were carvacrol (71% and 34.6%, respectively) and thymol (5–7%, respectively). In addition, two unusual isomers, 2-isopropyl-4-methylphenol and 4-isopropyl-2-methylphenol, were found and identified by comparison with mass spectral data and retention indices and tentatively synthesized.
