Separation of tocopherol and tocotrienol
Abstract
Abstract PURPOSE:To extract and separate tocopherols and tocotrienols having the activity of vitamin E and useful as an antisterile agent of animals, from the leaves and stalks of crops such as rice, wheat, corn, etc. by using an organic solvent as the extraction solvent. CONSTITUTION:The leaves and stalks of crops such as rice, wheat, barley, corn, rye, etc. during the growing stage or after harvest, e.g. rice straw, wheat straw, leaves or stalks of corn, etc. are pulverized or chopped, optionally dried, and extracted with an organic solvent such as an alcohol, ether, ketone, etc. or their mixture or a mixed solvent composed of said organic solvent and a water- insoluble organic solvent. Tocopherols and tocotrienols are extracted and separated by this process. The extract is treated with an aqueous solution of alkali metal hydroxide, carbonate, etc. to obtain concentrated tocopherols and tocotrienols. USE:Additive for nutrious food and cosmetics.
