Abstract

The metabolic fate of umbelliferone was studied by the quantitative analysis of urinary excrete of rabbits. The orally administered umbelliferone was converted into glucuronide (44.32%) and ethereal sulfate (19.10%) accompanying unchanged umbelliferone (20.23%). An extractor of high efficiency was designed to be employed for the continuous extraction of urinary metabolites.
