原始语种摘要: N -acetylneuraminic acid is an important member of sialic acids which is a family of nine-carbon carboxylated sugars most frequently found in terminal position in glycoconjugates. It was widely distributed in different portions of organisms. In this study, a method of ultra performance liquid chromatography–tandem mass spectrometry was developed for the determination of N -acetylneuraminic acid in poultry eggs. The N -acetylneuraminic acid was freed by heating the materials in 0.1 M H2SO4 at 80°C for 2 h. Then, chloroform reagent was used to eliminate phospholipids, cholesterol and other organic impurities, meanwhile, it was able to precipitate protein. In the cleanup step, C18 solid phase extraction columns were used to purify the matrix. Determination of...
