Five steroidal compounds were estimated in two samples, A and B, derived from hydrolysis of rice bran. The present study presents identification and quantitative analysis of these compounds. As a result of gas chromatography and mass spectrometric analysis, they were identified as campesterol, β-sitosterol, 24-methylene-cycloartanol and cyclobranol with their standard compounds, respectively. The ratio of these compounds were determined to be 4.55, 1.00, 7.59 and 1.18 in sample A and 2.44, 1.02, 1.41, 1.00 and 1.95 in sample B by gas chromatography.
