摘 要：
采用草酸蒸煮处理玉米皮制备阿魏酰低聚糖酯,并对其进行体外抗氧化活性实验.研究玉米皮阿魏酰低聚糖酯对·OH、DPPH自由基、的清除作用,同时测定还原力和抗氧化能力指数.结果表明:阿魏酰低聚糖酯对·OH、DPPH自由基和O2-·均具有良好的清除能力,且还原力和抗氧化能力指数都优于阿魏酸.

摘 要：
Feruloylated oligosaccharides were prepared by autoclaving maize bran in oxalic acid solution and their in vitro antioxidant activity was studied.The results showed that the feruloylated oligosaccharides possessed strong free radical scavenging capacity against hydroxyl,1,1-diphenyl-2-picrylhydrazyl(DPPH) and superoxide anion free radicals.These oligosaccharides also showed higher reducing power and oxygen radical absorbance capacity than ferulic acid.
