New sterylglycosides; tetraglycosylsterol and pentaglycosylsterol were isolated in addition to the known mono-, di- and triglycosylsterols from rice bran and studied for the chemical structures. In both the lipids, the principal sterol components were sitosterol, campesterol and stigmasterol; the component sugar was essentially only glucose, glucose units of which were linked with β 1, 4-bonds. Based on these data, the representative tetraglycosylsterol and pentaglycosylsterol were characterized as cellotetraosylsitosterol and cellopentaosylsitosterol, respectively.
