Opis ogólny

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

Zastosowanie

The analytical standard can also be used as follows:
  • Development and validation of a 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
  • 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)
  • 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

Phytosterols and tocopherols are commonly used in food and pharmaceutical industries for their health benefits. Current analysis methods rely on conventional liquid chromatography, using an analytical column, which can be tedious and time consuming. However, simple, and fast analytical methods

Understanding the responses of crops to elevated atmospheric carbon dioxide concentrations (E[CO2]) is very important in terms of global food supplies. The present study investigates the effects of CO2 enrichment (to 800 μmol mol-1) on the physiology of soybean plants and the

Tocopherols are lipid-soluble antioxidants synthesized in plastids of plants and other photosynthetic organisms. The four known tocopherols, α-, β-, γ-, and δ-tocopherol, differ in number and position of methyl groups on their chromanol head group. In unstressed Arabidopsis (Arabidopsis thaliana)

The effect of climate warming on the reproductive success of ectothermic animals is currently a subject of major conservation concern. However, for many threatened species, we still know surprisingly little about the extent of naturally occurring adaptive variation in heat-tolerance.
