Abstract
The amount of lipoperoxides in serum of normal pregnant women was examined by TBA metnod ot Yagi, Nishigaki and Ohama. In the second and the third trimester, higher level of TBA value than that of non-pregnant women as well as than that of the pregnant women in the first trimester was observed. TBA values of the lipids extracted from the sera with chloroform・methanol mixture (2 : 1) showed the same tendency. By separating serum lipids using thin layer chromatography, triglyceride was found to show the highest TBA value among the lipids separated.
