Description générale

α-Tocopherol is a form of fat-soluble vitamin E and shows anti-oxidant, anti-inflammatory, anti-cell proliferative, and anti-cancer properties.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Application

The analytical standard can also be used as follows:

  • Simultaneous determination of vitamin A and all four tocopherol isomers in human serum samples by ultra-high performance liquid chromatography (UHPLC) combined with fluorescence detection following their liquid-liquid extraction (LLE)
  • Multi-residue analysis of vitamin B (B1, B2, B5, and B9), and vitamin E (α-tocopherol, β-tocopherol, α-tocotrienol, and β-tocotrienol) in grass and grain samples of four different wheat varieties by liquid chromatography-electrospray ionization/multistage mass spectrometry (LC-ESI-MS/MS)
  • Separation and estimation of four tocopherols and four tocotrienols in pecan nut cultivar samples using non-aqueous reversed-phase high-performance liquid chromatography (NARP-HPLC) coupled with atmospheric pressure chemical ionization-tandem mass spectrometric (APCI-MS/MS) detection
  • Analysis of different cold pressed oil samples to detect and quantify eight tocol- homologs using a chemometrically-assisted optimized high-performance liquid chromatography (HPLC) with fluorescence detection (FLD) based method
  • Multi-residue determination of tocopherols in aromatic peanut oil (APO) and four refined vegetable oils using high-performance liquid chromatography with UV detection to detect adulteration
