Among the acetone extracts from the eleven samples of Kokuto, those from three samples showed antioxidative activities, with samples Nos. 1 and 7 showing activities close to that of BHA. Sample No.12,processing by the same mill as sample No.1,had a high yield but no activity in the hexane extract. In the dichloromethane extracts, four samples showed stronger activities than that of α-tocopherol. The sample Kokuto A obtained a higher amount in yield than that of the other samples and seemed to contain some strong antioxidative substances extractable with dichloromethane. The isolation of such antioxidative substances are under investigation., 紀要論文}, pages = {305--308}, title = {沖縄産黒糖の抗酸化性について(生物資源科学科)}, year = {1994} }
