Fatty acid,tocopherol, and sterol content of three <Emphasis Type="Italic">Teucrium</Emphasis> species from Tunisia

In the present study analyses concerning the composition of vitamin E, sterols, triglycerides, and fatty acids of three Teucrium species (Teucrium alopecurus, T. nabli, and T. polium) seed oil were performed. Linoleic, linolenic, and palmitic were the major fatty acids. The oil was characterized by a high amount of phytosterol, wherein clerosterol, sitosterol, and stigmasterol are the main constituents. The amount of tocopherol is nearly 550 mg/kg of oil, with α-tocopherol as the major isomer. Information concerning the composition of Teucrium seed oil is very important for evaluating the therapeutic effect of this oil.
