title: Metabolism of beta-ionone. Isolation, characterization and identification of the metabolitesin the urine of rabbits.
abstract: 1. Rabbits dosed orally with beta-ionone excreted in the urine unchanged beta-ionone, 3-oxo-beta-ionone, 3-oxo-beta-ionol, dihydro-3-oxo-beta-ionol and 3-hydroxy-beta-ionol. 2. Excretion products were isolated as 2,4-dinitrophenylhydrazone derivatives (beta-ionone, 3-oxo-beta-ionone, 3-oxo-beta-ionol and dihydro-3-oxo-beta-ionol) and as p-nitrobenzoate derivatives (3-oxo-beta-ionol, dihydro-3-oxo-beta-ionol and 3-hydroxy-beta-ionol), which were characterized and identified by comparison with the synthetic authentic compounds. 3. The glucuronides of 3-oxo-beta-ionol and dihydro-3-oxo-beta-ionol were also detected in the urine. The latter compound was isolated as free glucuronide, sodium salt and 2,4-dinitrophenylhydrazone.
