摘要
Abstract
In this study feruloylated oligosaccharides(FOs)was released from maize bran by hydrochlonc acid hydrolysis,and feruloyl arabinose(F-Ara)was obtained by D301 macroporous resin chromatography followed by polyamide resin purification from FOs.After structural identification,the antioxidant activity of F-Ara was evaluated in vitro by DPPH and superoxide radical scavenging activity assay and reducing power assay.F-Ara exhibited a good radical-scavenging activity in vitro when compared to standard antioxidants such as ferulic acid (FA),BHA and L-ascorbic acid(VC).The radical-scavenging activity depended on the concentration and increases with increasing dose of sample.The highest reducing value of F-Ara compared with FA and VC at a dosage of 0.6 mmol/L indicated that F-Ara had a considerable reducing power.The present study suggested that F-Ara can be a natural and efficient antioxidant used in food,medicine and cosmetic.关键词
