Seven kinds of hydroxychromon derivatives and 5 kinds of hydroxychroman derivatives were prepared and their action in preventing oxidation of vitamin A was examined. The efficacy of hydroxychromon and monohydroxychroman was rather weak, but that of dihydroxychroman derivatives was strong, 7, 8-dihydroxy-2-methyl- and 7, 8-dihydroxy-2, 3-dimethyl-chroman showing powerful preventive action against oxidation. Their action was found to equal that of N. D. G. A.
