Composition and infraspecific variability of essential oil from Thymus herba barona Lois
Abstract
The composition of the essential oils of individual plants of Thymus herba barona Lois. growing wild in Corsica was investigated by GC, GC/MS an carbon-13 NMR. Eight groups of essential oil were distinguished: (i) thymol, (ii) carvacrol, (iii) linalool, (iv) geraniol, (v) α-terpenyl acetate, (vi) terpinen-4-ol, (vii) carvone and cis-dihydrocarvone. Three chemotypes -thymol, carvacrol and linalool - are common in the genus Thymus, two others - geraniol, α-terpenyl acetate - are scarce, while the latest three ones - terpinen-4-ol, carvone and cis-dihydrocarvone are quite original. It is the first time that the cis-dihydrocarvone chemotype is described in the genus Thymus
