1. Metabolic conversion of β-carotene to vitamin A was studied by oral administration to rats, rabbits as well as frogs, and several unknown compounds were found on paper chromatograms.2. Further studies on metabolic conversion of β-carotene to vitamin A in vitro by rat tissue homogenate, revealed two metabolic intermediates in paper chromatograms.Compound I with an absorption maximum at 296mμ in ethanol was identified as β-ionone, and the Compound II with an absorption maximum at 365mμ in petroleum ether was identified as a kind of vitamin A aldehyde-proteincomplex.These findings lead to the plausible conclusion that vitamin A aldehydeprotein-complex may be an intermediate in the metabolic conversion of β-carotene to vitamin A alcohol.
