Abstract : The aim of this study is to compare/contrast the colostrum lipid composition of 53 Burkinabe women, collected in 2005 at the Maternity of Centre Medical Saint Camille in Ouagadougou (Burkina Faso), with similar data obtained in breast milk, five years ago and then to show the evolution of this important aliment. The fatty acid composition of colostrum samples was determined by Gas-liquid Chromatography-Mass Spectrometry. Saturated lipids (C8:0-C:14-0) showed a progressive increasing trend in the Burkinabe woman colostrum with respect those already measured five years ago. The C15:0-C24:0 fractions were found costantly higher, but their trends were in progressive decrement. The 18:2n-6 fraction (linoleic acid) reached the highest value in the third day post partum. The 18:3n-3 was constantly higher in the second and third days. The 20:4n-6 (arachidonic acid) and LC n-6 PUFA were lower ever since the first day, but with a trend to increase. Also 22 : 6n-3 and LC n-3 PUFA were costantly lower. The 18:2n-6/18:3n-3 and LC n-6/LC n-3 ratios were lower and higher, respectively, if compared with those already measured five years ago. These results suggest the need to improve alimentary habits of mothers in order to restore the balanced n-6/n3 PUFA ratio in their colostrums.
