A New Automated Determination of Xanthurenic Acid in Human Urine

[摘要] An automated determination for xanthurenic acid in urine was devised based upon its reaction with 2,6-dichloroquinonechlorimide. The separation of xanthurenic acid from interfering substances, such as urine chromogens and phenolic compounds other than xanthurenic acid, was performed by using Sephadex G-10. The effluents containing the xanthurenic acid were determined automatically. As a result of the high sensitivity of this procedure, concentration technics are unnecessary.
