Abstract
Acyl derivatives of glycosyl-L-ascorbic acids which have a higher oil-solubility than L-ascorbic acid, glycosyl-L-ascorbic acids, and inorganic esters of L-ascorbic acid such as phosphates and sulfates of L-ascorbic acid. When administered to living bodies, the acyl derivatives easily permeate into living tissues to release L-ascorbic acid, resulting in an exertion of the physiological action inherent to L-ascorbic acid. Thus, the derivatives can be arbitrarily used in food products, cosmetics, and pharmaceuticals.
