HPPD gene expression in relation to vitamin E content in spring barley

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009
The enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) has a very important role in the biosynthetic pathway of vitamin E. Its activity influences the final level of tocols in plant tissues. Seven barley cultivars with different vitamin E level were grown

An Efficient Solid-Phase Extraction-Based Liquid Chromatography Method to Simultaneously Determine Diastereomers α-Tocopherol, Other Tocols, and Retinol Isomers in Infant Formula

Journal of Food Quality, 2021
The separation and simultaneous quantitation of diastereomers of DL-α-tocopherol, eight tocol forms, and retinols (trans and cis) have been conducted by reversed-phase liquid chromatography followed by solid-phase extraction.

Molecular and biochemical analysis of the estrogenic and proliferative properties of vitamin E compounds

Frontiers in Oncology, 2016
Tocols are vitamin E compounds that include tocopherols (TP) and tocotrienols (TT). These lipophilic compounds are phenolic antioxidants and are reportedly able to modulate estrogen receptor β (ERβ).

Exploring combi-lipase catalysis of Eversa® Transform and Candida rugosa lipases for enzymatic hydrolysis of crude palm oil: Effects on fatty acid yield and retention of carotene and tocols.

International Journal of Biological Macromolecules
Several lipases have been used to catalyze the hydrolysis of crude palm oil (CPO) to concentrate palm phytonutrients. Previously, the retention of phytonutrients during hydrolysis has been improved with a small addition of ethylenediaminetetraacetic acid.

Isolation of Palm Tocols Using Supercritical Fluid Chromatography [PDF]

Journal of Chromatographic Science, 2004
Crude palm oil contains 600 to 1000 ppm of tocols in the form of tocopherols and tocotrienols. These palm tocols have been isolated and analyzed in the past by various chromatographic techniques such as open column chromatography, high-performance liquid chromatography, as well as thin-layer chromatography.
