Multivariate Calibration Applied to the Simultaneous Spectrophotometric Determination of Ascorbic Acid, Tyrosine and Epinephrine in Pharmaceutical Formulation and Biological Fluids

摘要

Background: Epinephrine (EP), ascorbic acid (AA) and tyrosine (TY) usually coexist together in human blood and are considered as important molecules for physiological processes in human metabolism. Thus, to determine these compounds in biological fluids, we need to develop sensitive, simple and rapid methods.
