Composition of essential oils of Laurus nobilis, L. nobilis var. angustifolia and Laurus azorica.
The essential oils of Laurus nobilis, L. nobilis var. angustifolia and L. azorica were investigated by means of GLC, IR, PMR, CMR and GC-MS. The composition of the oils of the first two mentioned species was about the same with as main constituent 1,8-cineole, whereas the oil of L. azorica was different with low content of 1,8-cineole (10% vice 40-50%), absence of spathulenol, high content of alpha- and beta-pinene and presence of alpha-copaene, cinnamyl acetate, allo-aromadendrene, beta-eudesmol, beta-caryophyllene oxide and 1 (12), 8 (15)-caryophylladiene-9alpha-ol. About 50 components were tentatively identified.
