When radioactive pyridoxine hydrochloride was orally supplemented to evaluate vitamin Be metabolism in adult domestic cats, two unknown radioactive compounds (compounds X and Y) were excreted in the urine.The Rf values of compound X (7 f values 0.95, 0.83, 0.2, 0.5, and 0.62) and compound Y (Rf values 0.35, 0.20, 0.22, 0.32, and 0.25) were identical to those of pyridoxine-3-sulfate and Wmethylpyridoxine, respectively, but not to those of pyridoxine (Rf values 0.73, 0.83, 0.78, 0.52, and 0.62) in various solvent systems [0.5% ammonium hydroxide, 95% ethanol, chloroform-methanol (3 1 vol/vol), isoamyl alcohol-acetone-triethyl-amine-water (24 18 8 6 vol/vol), and 2-butanol-1.5N ammonium hydroxide (3 1 vol/vol), respectively] by TLC on silica gel plates.
