Abstract
(UA), and detection limits of 23.1 μM (AA), 0.2 μM (DA), and 1.7 μM (UA). The method has been validated with a synthetic urine sample to yield ∼100% recoveries for all three analytes. The developed method has been further applied in the investigation of the peroxide scavenging activity of UA.
