Abstract: The present invention provides a novel phytochemical-fructooligosaccharide conjugate having a structure in which a phytochemical in the form of phenolic acid is conjugated to a portion of saccharides constituting a fructooligosaccharide backbone. Compared to corresponding phenolic acid phytochemicals, the novel phytochemical-fructooligosaccharide conjugate according to the present invention is hardly decomposed under oral-gastrointestinal transit conditions such that most of the phytochemical-fructooligosaccharide conjugate may reach the large intestine. Thus, the novel phytochemical-fructooligosaccharide conjugate has good bioavailability in the large intestine when orally administered.
