Descrizione generale

β-Tocopherol is a form of fat-soluble vitamin E and shows anti-oxidant, anti-inflammatory, anti-cell proliferative, and anti-cancer properties.

Applicazioni

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 (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
  • 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

As integral regulators in plant development and stress response, microRNAs (miRNAs) themselves need to be tightly regulated. Here, we show that tocopherols (vitamin E), lipid-soluble antioxidants synthesized from tyrosine in chloroplasts, positively regulate the biogenesis of miRNAs. Tocopherols are required

Protocolli

Determination of Vitamin A and E Using HPLC with UV Detection Following the Chinese National Standard (GB) Method

Following GB method for Vitamin A and Vitamin E as it is written with a 250 x 4.6 mm Ascentis® Express C30 column gives baseline resolution between the critical pair (gamma-, and beta-tocopherol; peaks 3 and 4).
