DescriptionDelta-Tocopherol, also known as RRR-δ-tocopherol or 8-methyltocol, belongs to the class of organic compounds known as tocopherols. These are vitamin E derivatives containing a saturated trimethyltridecyl chain attached to the carbon C6 atom of a benzopyran ring system. The differ from tocotrienols that contain an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain. Thus, delta-tocopherol is considered to be a quinone. Delta-Tocopherol exists in all living organisms, ranging from bacteria to humans. Delta-Tocopherol is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. delta-Tocopherol is found in Calendula officinalis, Campanula medium, Carum carvi L. , Caryodendron orinocense, Cocos nucifera L. , Crataegus monogyna, Guarea kunthiana, Schefflera taiwaniana, Hippophae rhamnoides, Hypericum ericoides, Juglans regia L. , Linum usitatissimum, Muntingia calabura, Olea europaea, Origanum vulgare, Psophocarpus tetragonolobus, Radula marginata, Radula perrottetii, Rubus idaeus, Salvia rosmarinus, Secale cereale L. , Sesamum indicum, Jungermannia infusca, Spinacia oleracea, Potamogeton pectinatus, Torreya nucifera and Vaccinium macrocarpon Aiton . delta-Tocopherol was first documented in 1999 (PMID: 10385606). Based on a literature review very few articles have been published on delta-Tocopherol.
