ABSTRACT:
A steam stripping substance, which is obtained by steam distillation of sesame oil under reduced pressure and contains sesamin analogues substantially, is mixed with water, a water-soluble solvent or their mixture serving as solvent. Sesamin analogues are caused to precipitate in this mixed system in the presence of more than one equivalent of an alkali with respect to the acid value of the steam stripping substance. The precipitated sesamin analogues are then separated from the mixed system.
