大豆磷脂的分析与检测

摘要

Perssad of soybean lecithin was detected by paper chromatography,the soybean lecithin components was also analysed by TLC.The samples were tested for further research by FTIR.Paper chromatography analyzing show that soybean lecithin contain choline,ethanolamine,nositol and serine when the soybean lecithin was hydrolyzed.Lysophosphatidylcholine,sphingomyelin,phosphatidylcholine and phosphatidyl ethanolamine is in soybean lecithin when detected by TLC and FTIR.%通过利用纸层析来检测大豆磷脂中的基团,运用薄层层析法对大豆磷脂的各个成分进行分析,并用红外光谱技术对磷脂样品进一步分析.结果表明:纸层析分析表明大豆磷脂水解后,内部含有胆碱、乙醇胺、肌醇和丝氨酸这4种基团,薄层层析检测和红外光谱均表明大豆磷脂中有溶血磷脂酰胆碱、鞘磷脂、磷脂酰胆碱和磷脂酰乙醇胺等.
