Tocole mit Methoxygruppen

Helvetica Chimica Acta, 1949
AbstractEs wurden ein Monomethoxytocol, ein Monomethyl‐methoxytocol und das 5,7‐Dimethyl‐8‐methoxy‐tocol synthetisiert, ihre Acetate und Allophanate dargestellt und die Acetate auf Vitamin‐E‐Wirkung geprüft. Nur 5,7‐Dimethyl‐8‐methoxy‐tocol‐acetat besass in Dosen von 60 mg volle Vitamin‐E‐Wirkung.

Carotenoids, tocols and retinols evolution during egg pasta – making processes

Food Chemistry, 2012
Abstract The available literature reveals that vitamin decrease in cereal products occurs after technological treatments, depending on several physical and chemical factors, such as light, temperature, pH, O2, food composition and the presence of antioxidants.

Tocol emulsions for drug solubilization and parenteral delivery

Advanced Drug Delivery Reviews, 2004
Tocols represent a family of tocopherols, tocotrienols, and their derivatives, and are fundamentally derived from the simplest tocopherol, 6-hydroxy-2-methyl-2-phytylchroman, which is referred to as "tocol". The most common tocol is D-alpha-tocopherol, also known as vitamin E.

Advances in the Use of Tocols as Drug Delivery Vehicles

Pharmaceutical Research, 2006
There has been increasing interest in recent years in the drug delivery applications of tocols and their derivatives. Their biocompatibility and potential to deliver both poorly soluble and water-soluble drugs make tocols attractive as drug delivery vehicles.

Über einige, den Cumaranring enthaltende Tocole

Helvetica Chimica Acta, 1948
AbstractEs wurden 3 Tocopherol‐ähnliche Verbindungen mit Cumaranringen anstelle von Chromanringen synthetisch hergestellt und auf Vitamin E‐Wirkung geprüft. Sie erwiesen sich erheblich weniger wirksam als die verwandten Chromane.

‘Tocol‐omic’ Diversity in Wild Barley, Short Communication

Chemistry & Biodiversity, 2011
AbstractHordeum spontaneum, wild barley, is the direct progenitor of domestic barley, Hordeum vulgare, an economically important ingredient of animal feed, beer, soy sauce, and more recently, of nutraceuticals. Domestic barley has also been used in the past as a medicine.

Chromatographic analysis of tocol-derived lipid antioxidants

Journal of Chromatography A, 2000
This paper provides a comprehensive overview of existing chromatographic methods for the analysis of tocol-derived lipid antioxidants in various sample matrices. After a brief introductory discussion on biological and nutritional aspects of the vitamin E active compounds, the review focuses on various techniques for the isolation, purification ...

Relative autoxidative and photolytic stabilities of tocols and tocotrienols

Lipids, 1976
AbstractThe relative stabilities of selected individual tocols and tocotrienols and of equimolar mixtures of either α‐ plus γ‐ or α‐ plus δ‐ tocopherols were determined in methyl myristate and methyl linoleate during autoxidation and photolysis. Solutions containing 0.05% of the appropriate tocopherol(s) or tocotrienols were subjected to UV light (254 ...

Oxidation of Corn Oils with Spiked Tocols

Journal of the American Oil Chemists' Society, 2011
AbstractStripped corn oils with added tocopherols and tocotrienols, at concentrations between 100 and 5,000 ppm, were used to evaluate antioxidant activity of these tocol compounds. The formation of lipid hydroperoxides, measured as peroxide value (PV), was accelerated at 60 °C in the dark for 5 days.

Gamma-tocotrienol, a tocol antioxidant as a potent radioprotector

International Journal of Radiation Biology, 2009
To assess the radioprotective potential of gamma-tocotrienol.To optimise its dose and time regimen, gamma-tocotrienol (GT3) was injected subcutaneously (SC) at different doses into male CD2F1 mice [LD(50/30) (lethal radiation dose that results in the mortality of 50% mice in 30 days) radiation dose of 8.6 Gy with vehicle].
