AB  - Flaxseed (Linum usitatissimum L.) oil was obtained via subcritical n-propane 
      fluid extraction (SubFE) under different temperatures and pressures with an 
      average yield of 28% and its composition, purity and oxidative stability were 
      compared to oils obtained via conventional solvent extraction methods (SEMs). 
      When the oxidative stability was measured by differential scanning calorimetry, 
      the oil was found to be up to 5 times more resistant to lipid oxidation as 
      compared to the SEM oils. Direct infusion electrospray ionization mass 
      spectrometry (ESI-MS) analysis showed characteristic and similar TAG profiles for 
      SubFE and SEMs oils but higher purity for the SubFE oil. The flaxseed oil content 
      of beta-tocopherol, campesterol, stigmasterol and sitosterol were quantified via 
      GC-MS. SubFE showed to be a promising alternative to conventional SEM since SubFE 
      provides an oil with higher purity and higher oxidation stability and with 
      comparable levels of biologically active components.
