The chemical composition, antioxidant and antimicrobial activities of essential oils isolated by hydrodistillation from the aerial parts of wild endemic Moroccan Thymus maroccanus at different developmental stages (vegetative, flowering and post-flowering) were evaluated. The yield of essential oils (v/w%) based on dry weight at different stages were: vegetative (2.14%), flowering (leaves: 1.80%; flowers: 3.46%), and post-flowering (leaves: 0.98%; post-flowers: 2.46%). Analysis of the essential oils by GC/MS revealed the presence of 28 components represented mainly by monoterpenes, both oxygenated (59.4–79.4%) and hydrocarbons (14.3–34.2%). The ranges of major constituents were as follow: carvacrol (14.1–77.6%), p-cymene (3.5–7.9%), γ-terpinene (3.8–6.6%) and α-pinene (1.2–7.8%). …

Thymus broussonetii, Thymus maroccanus and Thymus satureioides, are endemic Moroccan species that are intensively utilized because of their wide ranging medicinal and culinary properties. In an effort to preserve these over-exploited species, the effect of cultivation on the essential oil chemical composition, antioxidant and antimicrobial activities were investigated. The hydrodistilled oils obtained from wild and cultivated thyme species were analyzed by GC–MS. In total, 41 components were identified representing more than 98% of the oils, with carvacrol (26.0–71.6%), borneol (5.0–20.1%), γ-terpinene (4.0–8.9%) and p-cymene (5.2–10.3%) as the main constituents. Similar oil profiles were obtained from wild and cultivated T. maroccanus, …
