Abstract:
Summary A rapid and efficient procedure is described for extraction and determination of aminocaproic acid in horse urine. Urine was extracted by passing through a bonded silica column (Bond-Elut). The adsorbed drug was washed free of endogenous materials before being eluted. The extract was then examined by thin-layer chromatography and HPLC. The purity of the extract was determined by gas chromatography-mass spectrometry.
