A method is presented for quantitatively determining triclocarban in blood. Triclocarban is extracted from blood with ether, isolated by TLC, and measured through its UV absorption at 265 nm in methanol. This method is sensitive to 250 ng (50 ppb in 5 ml of blood) of free triclocarban with a relative standard deviation of 5.2%, correlated with a radiotracer analysis of 14C-labeled triclocarban. It has been applied successfully to the analysis of triclocarban in human and rabbit blood.

提出了一种定量测定血液中三氯卡班的方法。用乙醚从血液中提取三氯卡班,通过TLC分离,并通过在甲醇中在265 nm处的UV吸收进行测量。该方法对250 ng (血液5毫升为50 ppb) 的游离三氯卡班敏感,相对标准偏差为5.2%,与14c标记的三氯卡班的放射性示踪剂分析相关。已成功应用于人和兔血液中三氯卡班的分析。
