THERE IS DISCLOSED AN EPISESAMIN REFINING METHOD IN WHICH A MIXTURE OF SESAMIN COMPONENTS THAT CONTAINS SESAMIN, EPISESAMIN AND THE LIKE IS BROUGHT INTO CONTACT WITH AN AQUEOUS MEDIUM TO FORM A SLURRIED MIXTURE, AND THEREAFTER THE SOLIDS ARE SEPARATED FROM THE MIXTURE OR THE SLURRIED MIXTURE IS DISSOLVED IN A SUITABLE AQUEOUS MEDIUM UNDER HEATING AND, THEREAFTER, THE SOLUTION IS SLOWLY COOLED TO RECRYSTALLIZE, THEREBY YIELDING AN EPISESAMIN-ENRICHED COMPOSITION WITH AN INCREASED RELATIVE EPISESAMIN CONTENT. BY THE PRESENT INVENTION, EPISESAMIN CAN BE CONVENIENTLY AND EFFICIENTLY REFINED FROM A MIXTURE OF SESAMIN COMPONENTS THAT MAINLY COMPRISES SESAMIN AND EPISESAMIN. |
