A method for the determination of 15N enrichment and concentration of allantoin and uric acid simultaneously in urine using gas chromatography/mass spectrometry (GC/MS) is described. The urine samples contained acid and its oxidation product allantoin. The uric acid and allantoin were isolated using

A method was developed for the analysis and characterization of quercetin and kaempferol in urine following ingestion of Ginkgo biloba tablets. The method utilized gas chromatography/negative ion chemical ionization mass spectrometry of the trimethysilyl derivatives of the flavonoids. Limits of dete
Nitric oxide (NO) is formed by a class of NO synthases (NOS), which convert arginine into citrulline. A decreased in vivo NO availability can be the result of an increased NO inactivation or a decreased NO production. The latter can be assessed by measurement of isotopic enrichment of plasma citrull
