The analysis of 2'-fucosyllactose concentration in Korean maternal milk using LC-MS/MS.

ABSTRACT: Despite health benefits reported recently, 2'-fucosyllactose (2'-FL) concentration in maternal milk was not conclusively reported because it varies between countries and mothers. Particularly, its distribution among Korean mothers was not obtained from a reliable sample group yet. Thus, a dynamic range for 2'-FL concentration in Korean mothers' milk was investigated from 102 samples. A quantitative method using multiple reaction monitoring (MRM) by triple-quadrupole-mass spectrometry has been evaluated by a standard procedure of method validation. The 2'-FL concentration was in the range of 0.4 to 2.6 g/L overall. While the samples from secretor mothers (n = 80) contained 1.0 to 2.8 g/L of 2'-FL, the maternal milk from non-secretor mothers (n = 22) had 0.01 to 0.06 g/L of 2'-FL only. In ad
