Abstract

Three Italian strains of hyssop wildly grown in different natural habitats of the Abruzzi region (Central Italy) and classified as Hyssopus officinalis L. subsp. aristatiis, were characterized on the basis of their essential oil composition. The oils were obtained by steam distillation of the fresh aerial parts of the plants and analyzed by GC and GC/MS. Thirty-three compounds were identified. Relevant differences in the quantitative composition were observed among the oils so that the existence of three different chemotypes could be realized. In particular, one of the strains was characterized by high contents of myrtenol (32.6%) and β-pinene (19.3%), another contained β-pinene (24.7%) and 1,8-cineole (23.1%) as main components, while the third was very rich in methyl eugenol (43.9%) and limonene (15.9%). Whereas the latter two strains were similar in composition to oils from Spain and Montenegro, respectively, the former possessed a very unusual oil composition. © 61999 Allured Publishing Corp.
