The main component of coriander oil is (3S)-(+)-linalool (“coriandrol”). Mono- and polyunsaturated fatty aldehydes, although minor components,
contribute to the characteristic aroma of the oil because of their powerful
odor. In contrast to the seed oil, coriander leaf oil contains these aldehydes as
main constituents, for example, 2-decenal and 2-dodecenal.
Coriander is mainly cultivated in Eastern Europe (Russia, Ukraine, Hungary),
India, and Egypt. In the Soviet era, Russian Coriander oil was produced in large
amounts (600 t/yr) for the isolation of linalool as raw material for the domestic
fragrance industry. Today, coriander seed and leaf oils are produced on a much
smaller scale of some 10 t and are used for flavoring seasoning mixtures and in
perfume compositions.
