Analytical methods for mercapturic acids, the end-products of glutathione metabolism of the industrial solvents toluene and o-xylene (i.e., S-benzyl-N-acetylcysteine and S-(o-methylbenzyl)-N-acetylcysteine), added to human urine have been developed. The sensitivity is 2 ng/microliter (R.S.D. = +/- 13%) and 1 ng/microliter (R.S.D. = +/- 6.4%) urine for S-benzyl-N-acetylcysteine and S-(o-methylbenzyl-N-acetylcysteine, respectively, when using the h.p.l.c. method. The corresponding sensitivities for the g.l.c.-mass spectrometric method are 0.5 and 0.3 ng/microliter urine, respectively.
已开发出用于分析巯基尿酸的方法,巯基尿酸是工业溶剂甲苯和邻二甲苯谷胱甘肽代谢的终产物(即S-苄基-N-乙酰半胱氨酸和S-(邻甲基苄基)-N-乙酰半胱氨酸),添加到人体尿液中。使用高效液相色谱法时,S-苄基-N-乙酰半胱氨酸和S-(邻甲基苄基)-N-乙酰半胱氨酸在尿液中的灵敏度分别为2纳克/微升(相对标准偏差=±13%)和1纳克/微升(相对标准偏差=±6.4%)。气相色谱-质谱法的相应灵敏度分别为0.5和0.3纳克/微升尿液。
