Method of producing phenol-type natural antioxidative materials from processed sesame seed products

摘要

Phenol-type natural antioxidative materials containing analogs of sesamin or sesamolin are manufactured by processing a processed sesame speed product with an acid catalyst and subsequently condensing and separating the desired materials by a physical means such as extraction, distillation and adsorption. By qualitative analysis, the phenol-type natural antioxidative material thus concentrated and separated by a method of the present invention is found to contain analogs of sesamin (A, B and C) and sesamolin (D) having the following chemical structures: <IMAGE> (A) <IMAGE> (B) <IMAGE> (C) <IMAGE> (D)
