The concentration of the anticarcinogenic fatty acid, 9c, 11t-18:2, in human milk was determined by gas-liquid chromatography (GLC). The mean concentration of 20 samples from 5 women taken at 1, 7, 14, and 21 days was: 0.18% +/- 0.02; range, 0.14-0.28%. Identity was confirmed by GLC-mass spectrometry (MS). Conjugated isomers other than 9c, 11t-18:2 were not detected. The amounts were not changed by supplementation of the maternal diet with fish oil beginning on day 1 after the milk sample was taken.
采用气液色谱法(GLC)测定人乳中抗癌脂肪酸9c, 11t-18:2的浓度。对5名女性在产后第1、7、14和21天采集的20份样本进行检测,其平均浓度为:0.18%±0.02;范围为0.14 - 0.28%。通过气液色谱 - 质谱联用(MS)法确认了其特性。未检测到9c, 11t-18:2以外的共轭异构体。在采集乳汁样本后的第1天开始,母亲饮食中补充鱼油,其含量未发生变化。
