Carotenoids and tocols comparison in different Subspecies of Triticum turgidum and aestivum

Food Research International, 2023
Carotenoids and Tocols in six genotypes of Triticum turgidum ssp. durum, five of Triticum turgidum ssp. dicoccum, four of Triticum aestivum ssp. aestivum, and six of Triticum aestivum ssp. spelta were investigated. The aim of the present study was to identify, quantify, and compare the content of tocopherols, tocotrienols, and carotenoids in different ...

Vitamin E in foods: Determination of tocols and tocotrienols

Journal of the American Oil Chemists' Society, 1969
AbstractA method is described for the analysis of foods for the forms of vitamin E. Detailed procedures are given for extraction, saponification and partial purification by thin layer chromatography. The individual tocopherols (both tocols and tocotrienols) are identified and estimated as their trimethylsilyl ethers by gas liquid chromatography on SE ...

Optimization of tocol emulsions for the intravenous delivery of clarithromycin

International Journal of Pharmaceutics, 2008
In the present study, novel less-painful tocol emulsions for the intravenous delivery of clarithromycin were prepared and optimized. The therapeutically effective concentration of clarithromycin, 5mg/ml, was achieved using tocopherol succinate (TS) combined with oleic acid as lipophilic counterions.

A developmental profile of tocol accumulation in oat seeds

Journal of Cereal Science, 2013
Oats are a good source of many vitamins and minerals, including compounds that collectively constitute vitamin E, the tocols. Tocols are comprised of two subgroups, tocopherols and tocotrienols. Due to their potent antioxidant properties, attention has been given to the health benefits of tocols in oats.

Carotenoids, Tocols, and Retinols during the Pasta-Making Process

2015
This chapter reports the ‘state of the art’ of the influence of the pasta-making process on tocols, carotenoids, and retinols. Available literature reveals that processing may influence the levels of these compounds in the final products, depending on several physical and chemical factors, such as light, temperature, pH, O2, food composition, presence ...

Tocols as Antioxidant Molecules in the Agro-Food Field

2023
The presence of many different antioxidant molecules in foodstuffs and their by-products has attracted the scientific community's attention to their applications in finished foods due to their high bioactive power. Classes of molecules, such as phenolic compounds (phenolic acids, flavonoids, stilbenoids, and lignans), carotenoids, and tocols, provide ...

Comparison of antioxidant activities of tocol and its methyl derivatives

Lipids, 1968
AbstractIn tests with purified menhaden oil at 37C and with squalene at 37C and 50C, unsubstituted tocol, 7,8‐dimethyl tocol (γ‐tocol), and 8‐methyl tocol (σ‐tocol) were superior antioxidants to 5,7‐dimethyl tocol and 5,7,8‐trimethyl tocol (α‐tocol).

Separations of tocopherols and methylated tocols on cyclodextrin-bonded silica

Journal of Chromatography A, 1994
Abstract α-, β-, γ-, and δ-tocopherols (methyl-substituted tocols) and 5,7-dimethyltocol were separated by normal-phase HPLC on β- or γ-cyclodextrin-bonded silica (CDS) with fluorescence detection. The HPLC behavior of the tocol components was studied under various mobile phase conditions.

Tocol modified glycol chitosan for the oral delivery of poorly soluble drugs

International Journal of Pharmaceutics, 2012
The aim of this study was to develop tocol derivatives of chitosan able (i) to self-assemble in the gastrointestinal tract and (ii) to enhance the solubility of poorly soluble drugs. Among the derivatives synthesized, tocopherol succinate glycol chitosan (GC-TOS) conjugates spontaneously formed micelles in aqueous solution with a critical micelle ...
