Milk samples were collected from mothers at 2, 6, 12 and 16 weeks postpartum. Desmosterol was found to be present in all the milk samples. Identification of desmosterol was based on retention times with two gas liquid chromatography (GLC) columns and verified by GC-mass spectrometry. The concentration of desmosterol in breast milk increased significantly (P less than .05) from 0.6 mg/100 ml at 2 weeks to 1.3 mg/100 ml at 16 weeks postpartum. Desmosterol was not significantly correlated with total lipid, total cholesterol or free cholesterol in the milk.
在产后2周、6周、12周和16周从母亲处采集乳汁样本。发现所有乳汁样本中均存在胆甾烯醇。胆甾烯醇的鉴定基于在两根气液色谱（GLC）柱上的保留时间，并通过气相色谱-质谱联用仪进行验证。母乳中胆甾烯醇的浓度从产后2周时的0.6毫克/100毫升显著增加（P<0.05）至产后16周时的1.3毫克/100毫升。胆甾烯醇与乳汁中的总脂质、总胆固醇或游离胆固醇无显著相关性。
