Tocopherols are a class of chemical substances known collectively as vitamin E.
They are fat-soluble antioxidants that have the ability to neutralize harmful free radicals in
fat-soluble environments in the body.
Tocopherols are found in a variety of foods. Nuts, seeds, and vegetable oils are the richest sources, while significant amounts are
also found in green leafy vegetables and fortified cereals.
There are four different types of tocopherols: alpha, beta, gamma, and delta. Each has a slightly different
chemical structure and function.
Alpha-tocopherol is the most biologically active form and is the form most commonly found in supplements
and in the European diet.
In the US, gamma-tocopherol is the most common form in the diet due to a higher intake of soybean and corn oil.
Beta-tocopherol is not as common or as biologically active as alpha-tocopherol,
but it is still an important part of the vitamin E complex. Foods rich in beta-tocopherol include
certain nuts and seeds, vegetable oils, and some types of leafy green vegetables.
Delta-tocopherol is the least active tocopherol when it comes to vitamin activity in the human body.
It is usually in smaller amounts than alpha and gamma-tocopherols. The highest natural concentrations of delta-tocopherol can typically be
found in certain vegetable oils, like soybean oil and corn oil. Delta-tocopherol can also been found in some leafy green vegetables.
From a health perspective, tocopherols are crucial for normal neurological function and fertility, as well as acting as an antioxidant.
They are also involved in immune function, DNA repair, and other metabolic processes.
Deficiency of Vitamin E (tocopherols) can lead to neurological problems due to poor nerve conduction, muscle weakness, and retinopathy.
It's important to note that excessive consumption of alpha-tocopherol can potentially interfere with the absorption and function of
other forms of vitamin E, so it is usually recommended to get vitamin E from a balanced diet rather than supplements.
Examples of some tocopherols found in herbal leaf extracts are listed below:
Tea Leaves -
Green tea and black tea leaves contain alpha-tocopherol and gamma-tocopherol.
Herbs and Spices - Certain herbs and spices,
like oregano and paprika, are also rich in tocopherols. They contain mainly gamma-tocopherol, although alpha-tocopherol
can be present as well.
Green Leafy Vegetables - These are known to contain alpha-tocopherol,
the most biologically active form of Vitamin E. Spinach and kale, for example, are two leafy greens that are a good source of this tocopherol.
Cannabis Leaves - Some research has found that cannabis leaves contain alpha-tocopherol
The extraction process, including the solvents and methods used, can influence the concentration and types of tocopherols present in the final extract.
It is often the case that a balance needs to be found between fully-extracting all tocopherols while also ensuring that the compounds that are
obtained are of a high quality and not degraded.
At Celignis we have extensive experience in the design and optimisation of extraction protocols for a wide variety of chemical constituents from
many different biomass types. If needed we can also work on processes to separate and purify the target compounds.

This conference is being organised under the auspices of the Interreg Northwest Europe-funded THREE C Project, entitled 'Creating and sustaining Charcoal value chains to promote a Circular Carbon economy in NWE Europe'.
The conference will highlight both Irish stakeholders who are currently working in the biochar and carbon products sector, but also partners from the THREE C project (covering Netherlands, Luxembourg, Germany, Belgium, France and Wales, as well as Ireland) who have interesting stories and products to share.
