建立了同时分离和定量米糠油中生育酚、生育三烯醇和稻谷醇的反相高效液相色谱法。用荧光法定量测定生育酚和生育三烯醇，用光电二极管阵列法定量测定米扎酚（甾醇和三萜醇的阿魏酸酯）。化学电离质谱法鉴定了该方法分离的主要稻谷醇为阿魏酸环artenyl、阿魏酸24-亚甲基环阿魏酸、阿魏酸油菜甾醇、阿魏酸β-谷甾醇和阿魏酸环阿魏酸。研究发现，在不同制造商生产的完全加工的可食用米糠油中，这些重要营养成分的含量各不相同。
A reverse-phase high-performance liquid chromatography method was developed for the simultaneous separation and quantitation of tocopherols, tocotrienols and oryzanols present in rice bran oil. Tocopherols and tocotrienols were quantitated by fluorescence detection and oryzanols (ferulic acid esters of sterols and triterpene alcohols) by photodiode array detection. Chemical ionization mass spectrometry was used to identify cycloartenyl ferulate, 24-methylene cycloartanyl ferulate, campesteryl ferulate, β-sitosteryl ferulate and cycloartanyl ferulate as the major oryzanols separated by this procedure. The levels of these nutritionally significant components were found to vary in fully processed, edible rice bran oils from different manufacturers.
