Abstract
Novel oligoglycosylsterols, a series of sterylglycosides, were detected in the glycolipids of rice bran, and di- and triglycosylsterols were isolated and their structures were investigated. The principal sterol components were sitosterol, campesterol and stigmasterol; glucose was the only component sugar. The major species of diglycosylsterol and triglycosylsterol were characterized as D-glucopyranosyl-(.beta.1 .fwdarw. 4)-D-glucopyranosyl-(.beta.1 .fwdarw. 3'')-sitosterol, i.e., cellobiosylsitosterol and D-glucopyranosyl-(.beta.1 .fwdarw. 4)-D-glucopyranosyl-(.beta.1 .fwdarw. 4)-D-glucopyranosyl-(.beta.1 .fwdarw. 3'')-sitosterol, i.e., cellotriosylsitosterol, respectively.
