椰子纳塔培养液的抗氧化活性
Antioxidant Activities of Extracts from Nata De Coco Culture Medium
摘要
Abstract
Fresh and fermented nata de coco culture mediums were extracted, and these 2 extracts were determined by using peroxidation of phospholipids liposomes assay to observe their DPPH radical and hydroxyl radical scavenging activity, metal chelating activity, and ferric reducing power, and BHT and gallic acid were used as standards. The results indicated that the fresh nata de coco culture medium extract was higher in peroxidation of phospholipids liposomes inhibiting activity, DPPH radical and hydroxyl radical scavenging activity, ferric reducing power, and metal chelating activity than the fermented nata de coco culture medium extract. In addition, the total phenolic content determined by Folin-Ciocalteau's reagent was 1.863 7 mg/mL for the fresh nata de coco culture medium extract and 1.361 8 mg/mL for the fermented nata de coco culture medium extract.关键词
