Abstract:
Objective To detect 10 kinds of human milk oligosaccharides (HMOS) and compare their amounts during lactational stage.Methods Breast milk samples in different stages of lactation as colostrum (day 0-7 postpartum),transitional milk (day 8-15 postpartum),and mature milk (day 16-180 postpartum) were collected and 10 HMOS in those samples were detected and quantified by ultra high performance liquid chromatography-fluorescence detection after fluorescence labeling by using standard curves.Correlations between HMOS and lactation day were conducted by Person correlation analysis method,while the differences among three stages were calculated by ANOVA test.Results Ten HMOS were successfully separated and quantified under chosen chromatographic parameters.2'FL,3'SL,6'SL,LNT,LNnT and LNFP-I were negatively correlated and 3'FL was positively correlated with lactation days.They were different in three lactational stages (P ＜ 0.05),while P1,LNFP-V and LNnFP-V showed no correlation and difference (P ＞ 0.05).Conclusion The amount of HMOS changed during lactational stages.Seven HMOS were correlated with lactation days and different in three lactational stages (P ＜ 0.05).
