摘要
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) alpha-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, a-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. (C) 1998 Elsevier Science Ltd. All rights reserved.
