Metabolism

Tests performed in rats found the metabolite 3'-hydroxyisosafrole occurred in urine after oral ingestion of safrole as a minor metabolite, but this was not in urine of human test subjects.[1]

In rats and mice, 3'-Hydroxyisosafrole was found to lead to the creation of alkaloid metabolites. The metabolism of 3'-hydroxyisosafrole in the rat and mouse differed from 1'-hydroxysafrole. 3'-Hydroxyisosafrole rapidly underwent side-chain oxidation giving 3,4-methylenedioxycinnamic acid and 3,4-methylenedioxybenzoic acid. In the first 4 hours, the major urinary alkaloid metabolites 3,4-methylenedioxybenzoyl glycine and 3,4-methylenedioxycinnamoyl glycine, adducts of glycine, together accounted for 39% and 63% of the dose administered to rats and mice, respectively. The glucuronide of 3'-hydroxyisosafrole was not detected in the urine. Urinary excretion of the glucuronide of 1'-hydroxysafrole at 2 hours accounted for about 40% of a dose of 1'-hydroxysafrole.[2]
