摘要：

1. 1. The non-protein nitrogen fraction of four fish species from Lake Victoria was investigated. 2. 2. The presence of content of trimethylamine oxide (TMAO) was determined by the Conway microdiffusion assay and confirmed by 1H and 13C NMR spectroscopy and FAB mass spectrometry. 3. 3. Nile perch (Lates niloticus) and a Tilapia sp. contained exceptionally high levels of TMAO (150-200 mg/100 g) for freshwater fish species. 4. 4. TMAO was not present in the catfish Bagrus and Clarias from the same area. 5. 5. Concentrations of free amino acids were 2700-5000 μmol/100 g with taurine accounting for 50-75% of the free amino acids. © 1990.
