SIGMA 46401-U

ß-Tocopherol is a form of fat-soluble vitamin E and shows anti-oxidant, anti-inflammatory, anti-cell proliferative, and anti-cancer properties. The analytical standard in solution 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 (a-tocopherol, ß-tocopherol, a-tocotrienol, and ß-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
• Development and validation of normal-phase high-performance liquid chromatography (NP-HPLC) method, along with fluorescence detection, to simultaneously determine four tocopherols and four lignans in sesame oil samples
