The chemical composition of the seed oil obtained from Onopordon nervosum subsp. platylepis Murb, endemic of Tunisia was determined. The seed oil was composed of eight acids; the predominant components were linoleic, oleic and palmitic. Nine triacylglycerols were identified; the major compounds are LLL, LLO and LLP with respectively 30.1%, 20.3% and 14.6%. The sterols constitute 0.13% of the oil, sitosterol and ∆-7 stigmastenol being the main constituents. The alpha tocopherol was identified with a concentration of 599 mg/kg of seed oil.
