HPLC chromatogram of oryzanol showing (a) oryzanol standard (100 μg/mL) and (b) oryzanol in hexane extract (30 mg/mL) of germinated brown rice. Four isomers of oryzanol were detected corresponding to cycloartenyl ferulate, 24-methylene cycloartanyl ferulate, campestryl ferulate, and mixtures of β-sitosteryl ferulate and cycloartanyl ferulate, respectively.
