摘　　要：分别以麦麸、玉米芯、玉米麸皮为原料,采用酶法制备低聚糖阿魏酸酯,探讨其快速检测方法,并通过高效液相色谱法验证该法的准确性。结果表明,采用Amberlite树脂分离纯化可除去样品中的低聚糖(不含结合态的阿魏酸)、双波长分光光度法(345nm和375nm)结合还原糖法可用于对低聚糖阿魏酸酯进行准确定量。In this work,feruloylated oligosaccharides were prepared from each of three raw materials,namely,wheat bran,corn cob and corn bran,by enzymatic hydrolysis.A rapid method for determining feruloylated oligosaccharides was developed and verified by high performance liquid chromatography.Non-feruloylated oligosaccharides were removed by Amberlite resin chromatography,and the purified feruloylated oligosaccharide could be determined by using dual wavelength（DW） spectrophotometry（345 nm and 375 nm） coupled with the determination of reducing sugars after acidolysis.
