Purification and measurement of abscisic Acid and indoleacetic Acid by high performance liquid chromatography.

A procedure was selected for the simultaneous extraction and purification of abscisic acid (ABA) and indoleacetic acid (IAA). Unnecessary steps were eliminated and an accumulation of aqueous phase was avoided. The superior performance of diethyl ether (compared to ethyl acetate) for bulk purification and the superior resolution provided by 250 millimeter columns packed with 5-micrometer spheric...

Simultaneous determination of creatinine and uric acid in human urine by high-performance liquid chromatography.

An environmentally friendly reversed-phase HPLC method for simultaneous determination of creatinine and uric acid in human urine samples has been developed. Human urine samples were pretreated by dilution, protein precipitation, centrifugation and filtration, followed by HPLC separations using a reversed-phase C(18) column with an aqueous mobile phase of phosphate buffer. The retention loss of ...

DEVELOPMENT OF A METHOD FOR THE DETERMINATION OF 4-HYDROXY-3-METHOXYMANDELIC ACID (VANILLYLMANDELIC ACID) IN URINE BY PAPER CHROMATOGRAPHY

We have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (VMA) in urine. Concentrations of VMA in patients with neuroblastoma were increased in comparison to controls. The linearity was excellent in the concentration range tested. The within-assay coefficient of variation for control and patient urine was less than 2.2%. ...

Automated determination of 5-hydroxyindolylacetic acid in urine by high-performance liquid chromatography

5-hydroxyindolylacetic acid (5-HIAA), a major serotonin cata-bolite, is eliminated in urine. In carcinoid tumours, 95 ofwhich occur in the small intestine, large quantities of serotonin are secreted by the entero-chromaffin cells of Kultchizky-Masson. Early detection of these tumours is essential, since unless they are surgically treated in the initial stages then their prognosis is serious. Ea...
