基于超高效液相色谱-串联质谱同时测定婴幼儿配方乳粉中2'-岩藻糖基乳糖和乳糖-N-新四糖OA北大核心CSTPCD
Simultaneous determination of 2'-fucosyllactose and lactose-N-neotetraose in infant formula milk powder by ultra-performance liquid chromatography-tandem mass spectrometry
建立超高效液相色谱-串联质谱法(ultra-performance liquid chromatography-tandem mass spectrometry,UP-LC-MS/MS)同时测定婴幼儿配方乳粉中2'-岩藻糖基乳糖(2'-fucosyllactose,2'-FL)和乳糖-N-新四糖(lacto-N-neotetraose,LNnT).样品经水提取,沉淀法除蛋白、针式水系滤膜净化,以乙腈和10 mmol/L甲酸铵水溶液(含0.1％甲酸…查看全部>>
A method was established to simultaneously determine 2'-fucosyllactose(2'-FL)and lactose-N-neotetraose(LNnT)in in-fant milk powder by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).The sample was extracted by water,precipitated protein,and purified through a needle-type water system filtration membrane.Then the sample solution was separated using an amide column by gradient elution,within acetonitrile and 10 mmol/L ammonium form…查看全部>>
