Abstract Lemon oils were characterized by quantitative glass capillary gas chromatography. Components present to the extent of more than 0.05% were measured and identified by mass spectrometry. In expressed lemon oils, monoterpenes and geranial were the only components present at concentrations of 1.0% or more. In concentrated lemon oils, β-caryophyllene, linalool, neral, β-terpineol, neryl acetate, and geranyl acetate were present in some samples in amounts of 1% or more. Adulteration was detected by component concentrations outside characteristic ranges for oils judged to be authentic.
