Acyl sterol glycoside and sterol glycoside were isolated from brown rice grain, identified and examined for constituents, respectively. The acyl sterol glycoside was found to contain six fatty acids, two sugars and three sterols as the components, among which palmitic acid, glucose and β-sitosterol were predominant. The sterol glycoside was observed to include two sugars and three sterols as the components, among which glucose and β-sitosterol were dominating. It is conceived from the data that the representative sterol glycosides in rice grain would be β-sitosterol palmitoylglucoside and β-sitosterol glucoside.
