After the intraportal injection of retinoic acid-15-(14)C into rats, all-trans methyl retinoate, a cis isomer of methyl retinoate, retinoyl beta-glucurono-gamma-lactone, retinoic acid, and retinoyl beta-glucuronide were isolated from methanol extracts of rat bile by chromatography on anion-exchange resin and silicic acid columns and characterized on thin-layer plates of Silica Gel G. On the other hand, when bile was extracted with n-butanol or analyzed directly by thin-layer chromatography, only retinoyl beta-glucuronide and a very small amount of retinoic acid could be detected. Butanol extracts of the liver and the intestine, however, still contained a small radioactive nonpolar fraction. When retinoyl beta-glucuronide was incubated with an anion-exchange resin in the presence of methanol, several nonpolar products appeared. Apparently the methyl retinoate, retinoyl beta-glucurono-gamma-lactone, and most of the retinoic acid previously found in bile after retinoic acid administration are produced from retinoyl beta-glucuronide during the isolation procedure.
