- 論文の詳細を見る
Oryzanol-B was shown to be largely a mixture of cycloart-24-enyl ferulate (oryzanol-A) and 24-methylenecycloartanyl ferulate (oryzanol-C) by comparison of melting points of their derivatives and by degradation. Alcohol-B, obtained by saponification of oryzanol-B, was acetylated and ozonolysis of acetate afforded 24-oxocycloartanyl acetate and 3β-acetoxy-25,26,27-trisnorcycloartan-24-oic acid. Comparison of alcohol-B with reported triterpenes of rice-bran oil is described.
