• When vitamin A acid reacted with SbCl3 in chloroform, a purple red color having the maximum absorbance at 573mμ developed. The maximum gradually moved to 470mμ. Upon stopping the reaction by addition of water at the maximum color intensity at 573mμ, a yellow fluorescent substance (I) was mainly formed. Similar treatment at the maximum color intensity at 470mμ gave rise to a blue fluorescent substance (II).It was revealed from the findings of thin layer chromatography, ultraviolet absorption spectrum, SbCl3 reaction and the color of fluorescence that the substance I was changed to the substance II by the treatment with SbCl3. Reaction of vitamin A acid with HCl or acid clay gave rise to substance I but not to substance II.
