Originally thought to be a single chemical compound, it is now known to be a mixture of ferulic acid esters of phytosterols and triterpenoids, particularly cycloartenyl ferulate, 24-methylenecycloartanyl ferulate, and campesteryl ferulate, which together account for 80% of γ-oryzanol.

Minor constituents include Δ7-stigmastenyl ferulate, stigmasteryl ferulate, Δ7-campestenyl ferulate, Δ7-sitostenyl ferulate, sitosteryl ferulate, compestanyl ferulate, and sitostanyl ferulate.
γ-Oryzanol has been used in Japan for menopausal symptoms, mild anxiety, stomach upset, and high cholesterol. However, there is no meaningful evidence supporting its efficacy for these purposes. In the United States, it is sold as a sports supplement, but existing research does not support the belief that it has any ergogenic or testosterone-raising effects.
