Direct and simultaneous high-performance liquid chromatographic assay for the determination of p-aminobenzoic acid and its conjugates in human urine.

Abstract

Procedures based on high-performance liquid chromatography (HPLC) were developed for identifying and measuring p-aminobenzoic acid (PABA) and its conjugate metabolites in human urine after oral doses of PABA. p-Aminohippuric acid (PAH), PABA, p-acetamidohippuric acid (PAHA) and p-acetamidobenzoic acid (PADB) in urine were resolved and determined by HPLC… (More)
