The composition of the volatile oil from the leaves of Italian Thymus capitatus (L.) Hoffmanns was investigated in detail by a SPME-GC–MS method. Sixty-two compounds were identified; the major aroma constituents were carvacrol (72,8 %), γ-terpinene (6.4 %), p-cymene (2.3 %), β- caryophyllene (3.1 %) and β-linalool (2.1 %). The method developed for the volatile constituent analysis allowed the identification of a large number of sesquiterpenes, not reported previously in thymus oil, including α-guryunene, caryophyllene c, β- and γ-elemene, α-bergamotene, α- and β- himachalene, β-farnesene, α-muurolene, valencene, calamenene, humulene oxide I and II and α- bisabolol.

Abstract
The composition of the volatile oil from the leaves of Italian Thymus capitatus (L.) Hoffmanns was investigated in detail by a SPME-GC–MS method. Sixty-two compounds were identified; the major aroma constituents were carvacrol (72,8 %), γ-terpinene (6.4 %), p-cymene (2.3 %), β- caryophyllene (3.1 %) and β-linalool (2.1 %). The method developed for the volatile constituent analysis allowed the identification of a large number of sesquiterpenes, not reported previously in thymus oil, including α-guryunene, caryophyllene c, β- and γ-elemene, α-bergamotene, α- and β- himachalene, β-farnesene, α-muurolene, valencene, calamenene, humulene oxide I and II and α- bisabolol.Pubblicazioni consigliate
