Abstract
A process for separation of specific tocopherols from a mixture of tocopherols is disclosed. The process includes methods of separation of the tocopherols from residues of vegetable oil refining and other various food sources by dissolving in organic solvents and eluting over non-ionic adsorbent resins.
Claims18
A process for separating a tocopherol homologue mixture from tocopherol containing materials, said process comprising,
- a. dissolving a tocopherol containing material in a non-polar organic solvent,
- b. contacting the dissolved material with a non-ionic adsorbent resin,
- c. eluting adsorbed tocopherol homologues by passing a mixture of said organic solvent and a polar solvent through said resin, and
- d. collecting a tocopherol homologue mixture from the eluate.
A process for preparing a tocopherol homologue mixture from tocopherol containing materials, said process comprising,
- a. dissolving a tocopherol containing material in a first polar solvent,
- b. contacting the dissolved material with a strong basic anion resin, said resin being in the hydroxyl form,
- c. eluting adsorbed tocopherol homologues by passing a mixture of the first polar solvent and another polar solvent through said resin, and
- d. collecting a tocopherol homologue mixture from the eluate.
A process of isolating tocopherol homologues from a tocopherol homologue mixture, said process comprising,
- a. contacting a tocopherol homologue mixture dissolved in a non-polar solvent on a non-ionic adsorbent resin immersed in said non-polar solvent,
- b. passing a non-polar solvent mixed with a polar solvent through said resin containing the adsorbed tocopherol homologue mixture,
- c. collecting the eluate in fractions, and
- d. obtaining isolated tocopherol homologues from said fractions.
A process of isolating tocopherol homologues from a tocopherol homologue mixture, said process comprising,
- a. contacting a tocopherol homologue mixture dissolved in a first polar solvent on a strong base anion resin immersed in said first polar solvent, said resin being in the hydroxyl form,
- b. passing said first polar solvent mixed with a second polar solvent through said resin containing the adsorbed tocopherol homologue mixture,
- c. collecting the eluate in fractions, and
- d. obtaining isolated tocopherol homologues from said fractions.
