Essential oil of Laurus nobilis from Montenegro

Abstract

Steam distilled oil from the shoots, separated leaves, and stem, as well as from the flower of laurel (Laurus nobilis), grown in Montenegro, were analyzed by GC and GC/MS. The yield of essential oil was as follow: 1.4% in young shoots, 1.5% in the separated leaves, and 0.7% in separated stems. The main constituents of all investigated oils were 1,8-cineole, methyleugenol, and alpha-terpinyl acetate. Besides, alpha-pinene, beta-pinene, sabinene, and linalool were also present. It was interesting and important for commercial samples of laurel essential oil that there was no significant difference among the essential oil obtained from young shoots and those obtained from leaves and stem. The main constituents of the flower oil were 1,8-cineole (15.7%), beta-caryophyllene (9.5%), gamma-muurolene (7.1%), alpha-terpinyl acetate (6.5%), and methyleugenol (3.9%).
