Abstract
When vitamin A acid reacted with SbCl3 in chloroform, a purple red color having the maximum absorbance at 573 m[mu] developed. The maximum gradually moved to 470 m[mu]. Upon stopping the reaction by addition of water at the maximum color intensity at 573 m[mu], a yellow fluorescent substance (I) was mainly formed. Similar treatment at the maximum color intensity at 470 m[mu] 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 HC1 or acid clay gave rise to substance I but not to substance II.This publication has 2 references indexed in Scilit:
