As airhuff already said in his answer, γ-oryzanol (or just oryzanol) is a mixture of various sterol ferulates, which now usually are listed by their chemical names, however a couple of notable compendia^[4,5] list the two major^[6] formerly isolated constituents under names oryzanol A and C (since B turned out to be a mixture of A and C^[7]).

Your structure happens to be oryzanol A.
