| 摘 要： | 对以马铃薯淀粉为原料、全酶法制得的磷酸寡糖进行定性定量分析。通过采用薄层层析法(thin layer chromatography，TLC)和高效阴离子交换色谱-脉冲安培检测(high-performance anionic exchange chromatography-air pulsing ampere detectors，HPAEC-PAD)对磷酸寡糖组分进行检测分析，同时利用红外吸收光谱(infrared spectroscopy，IR)对其进行结构分析。结果表明：磷酸寡糖是结合有磷酸基团的并且聚合度在3～7之间的麦芽低聚糖混合物，以麦芽三糖至麦芽六糖组分居多。

| Abstract: | The current study was carried out to quantitatively and qualitatively analyze phosphorylated sligosaccharides prepared from potato starch by totally enzymatic method.The phosphorylated sligosaccharide composition was determined by thin layer chromatography(TLC) and high performance anionic exchange chromatography with pulsed amperometric detection(HPAEC-PAD).Infrared spectroscopy(IR) was used for structure elucidation.The analytes were identified as a mixture of maltooligosaccharides containing phosphate gr... |
