  • Method for producing purified tocotrienols and tocopherols using liquid chromatography
    Patent number: 6395915
    Abstract: A method separating tocotrienols from tocopherols and the isomers thereof on a large-scale or commercially feasible basis. Separation is accomplished using reverse phase partition liquid chromatography. The chromatography column is prepared using a stationary phase comprising a hydrophobic or aromatic reverse phase chromatography media. The mobile phase consists of a solvent which is capable of solubilizing the crude stock, tocotrienols and tocopherols. The chromatography column containing the stationary and mobile phases is loaded with a crude feed stock and the tocotrienols, tocopherols and/or isomers thereof are eluted at a predetermined linear velocity.
