Lipids were analyzed in 308 human milk samples, obtained during the first 5 wk of lactation from 17 mothers delivering at term. The mean triglyceride content increased mainly during the 1st postpartum wk and remained constant thereafter. In contrast, the cholesterol concentration decreased, whereas the phospholipids remained rather constant, resulting in a decrease of both the phospholipid/triglyceride and the cholesterol/triglyceride ratio. Circadian variations of the parameters analyzed were not uniform and differed in milks obtained from German mothers as compared to milks obtained from English mothers. The fatty acid composition was determined in the total lipids and in the phospholipid fraction as well. Changes were found in progressing lactation, but not during the day. Some data are discussed with regard to their possible physiological or physiochemical relevance.
对17名足月分娩母亲在产后第1周内采集的308份母乳样本进行了脂质分析。甘油三酯平均含量主要在产后第1周增加，此后保持稳定。相比之下，胆固醇浓度降低，而磷脂含量保持相对稳定，导致磷脂/甘油三酯和胆固醇/甘油三酯比值均下降。所分析参数的昼夜变化并不一致，与英国母亲的母乳相比，德国母亲的母乳中这些参数有所不同。还测定了总脂质和磷脂部分的脂肪酸组成。在泌乳过程中发现了变化，但在一天中未发现变化。讨论了一些数据可能的生理或物理化学相关性。
