Abstract :用いた含蜜糖試料の有機溶媒による抽出物には抗酸化力があった。抽出に適した有機溶媒としては, アセトンよりも塩化メチレンの方がすぐれていた。黒糖Aの抽出物の収量は, 他の黒糖試料よりも良好であり, 非極性溶剤に可溶な物質を除いたのちの塩化メチレン抽出物から, 強い抗酸化物質が単離できるものと予想された。
On the extraction with organic solvents, most of seventeen samples of Kokuto showed antioxidative activities. 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.
