Abstract
The phytosterols and their contents in the supercritical fluid extract from rice bran were analyzed by gas chromatography.Totally 3 phytosterol compounds were identified in the extract,including campesterol,stigmasterol and β-sitosterol and among them,β-sitosterol had the highest content(8.47 mg/g),followed by campesterol(1.97 mg/g) and stigmasterol(1.23 mg/g).
