The subjects of our study are twenty- nine pairs of mothers and their term infants from Chung Shan Memorial Hospital. Maternal venous blood was collected both in the first trimesterand at delivery, and cord blood was collected at delivery.Plasma vitamin Aand E levels were determined by high performance liquid chromatography andred blood cell phospholipid fatty acid profile were estimated by gas chromat- ography. Plasma vitamin A, E and vit E／total lipid of mothers were significan-tly greater than those of their term neonates (p ＜0.05). Maternal plasma vit E and vit E／total lipid were significantly greater in the first trimester thanat delivery (p ＜0.05). However, there was no difference of maternal plasmavit A between first trimester and at delivery. Red blood cell phospholipid o-leate and linoleate weresignificantly greater in maternal blood than in cord b-lood (p＜0.05). However, stearate and arachidonate were significantly greater in cord blood than in maternal blood (p＜0.05). There was significantly greater docosahexaenoate at delivery than in the first trimester (p ＜0.05). Maternal vit E was positively correlate between the first trimester and at delivery (r=0.38, p＜0.04). Maternal palmitate, linoleate, arachidonate and docdsahexaenoate were also positively correlated to those of their neonates. Gender of newb-orns did not affect the nutrients measured. In summary, the results suggested that there were significantly relationships between maternal blood and cord bl-ood for some nutrients. The nutritional status of mothers may affect the nutri-tional outcome of their neonates.
