Abstract

1. The metabolism of flavanone in the rat was studied after oral or intraperitoneal administration of the compound. Flavone and flav-3-ene together with five other unidentified minor metabolites were excreted in the urine. 2. The formation of flavanone metabolites was not suppressed by the administration of high doses of the antibacterial compounds aureomycin and phthaloylsulphathiazole. 3. No aromatic acids that could be attributed to ring cleavage of flavanone were detected. 4. Administration of 100 or 200mg of flavanone daily per rat caused some deaths during the 7–14-day period. 5. The application of combined gas–liquid chromatography/mass spectrometry and proton nuclear-magnetic-resonance spectroscopy to the separation and identification of the flavanone metabolites is described. 6. Measurement of the two major flavanone metabolites was carried out by gas–liquid chromatography.
