In search of a new hydrolysis method of saponin, it has been found that ultraviolet irradiation is a convenient procedure for hydrolysis of some oleanane triterpenoid saponins resulting in liberation of their genuine sapogenols. The subsequent investigation on structure requirement for ready photolysis of glycoside linkage in saponin has revealed that an uronic acid moiety directly connected to the sapogenol is an essential constituent in the carbohydrate portion.
