Fatty acid (FA) composition of total lipids (TL) and phospholipids (PL) in breast milli obtained from 20 normal delivery healthy women in Tokyo, Japan was analyzed. Total lipids were extracted from the samples and then FL, consisting of phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS), sphingomyelin (Sph) and phosphatidylinositol (PI), were separated by two-dimensional thin-layer chromatography. The FA composition of TL and PL was analyzed by gas liquid-chromatography. Compared with previous reports, the contents of eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22.6n-3) in TL from Japanese women were higher than those from Chinese and Canadian women, which may be caused by different dietary habits and food types consumed by those populations. The contents of arachidonic acid (AA; 20:4n-6), EPA and DHA in PE and PI were much higher than those in PC. In addition, no significant correlation of EPA or DHA content was found between TL and PL. The findings indicate that PL especially PE and PI in human milk may be a source of EPA :Ind DNA for infants in the rapid developmental stage. These results should be considered in infant formula production.
