Abstract
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.

A method of refining episesamin which comprises bringing into contact with an aqueous medium a mixture of sesamin components that is in a solid state or at least part of which is in a dissolved state, thereby forming a slurried mixture, and thereafter separating the solids from the mixture or performing recrystallization with an aqueous medium, thereby yielding an episesamin-enriched composition with an increased relative episesamin content.
