Essential oil variability of Thymus zygis growing wild in southeastern spain

Antimicrobial activity and chemical composition of Thymus vulgaris, Thymus zygis and Thymus hyemalis essential oils

“…From Thymus vulgaris grown in France and in other countries (Piccaglia, Marotti, Giovanelli, Deans, & Eaglesham, 1993) six chemotypes has also been reported, geraniol, linalool, c(gamma)-terpineol, carvacrol, thymol and trans-thujan-4-ol/terpinen-4-ol; from Thymus zygis subsp. gracilis, studies carried out by Morales (1986) and Sáez (1995b) about the essential oil variability of this species growing wild in south eastern Spain, showed that the most common chemotype of this thyme was thymol, although a pure linalool chemotype was also recorded. The chemical variability of the essential oil from wild T. hyemalis of the south eastern Iberian Peninsula has been reported also (Adzet, Granger, Passet, San Martín, & Simó n, 1976;Sáez, 1995a;Sotomayor, 1998).…”

Bioclimatic influence on essential oil composition in South Iberian Peninsular populations ofThymus zygis

“…To design the field sampling, bibliographical and herbarium reviews were carried out for previously known populations of Thymus zygis (12)(13). The selected samples were representative of the different dispersion areas for the taxa living in southern Spain, mainly in Andalusia.…”

“…However, there is also an important genetic influence on this composition (11). Some studies, for example, Sáez (12), describe no correlation between altitude, climatic belts, the precipitation zone and the essential oil composition of Thymus zygis.…”

Application of Chemometrics in Authentication of Herbal Medicines: A Review

“…Sylvestris and T. zygis subsp. gracilis (Sáez, 1995b). The composition of the essential oils of seven populations of T. camphoratus from Portugal were investigated separately by GC, GC-MS and 13 C-NMR (Salgueiro et al, 1997b).…”
