γ-谷维素是一种重要营养物质，尤其在米糠油中，其含量占1%~2%，是一种天然抗氧化剂。由于组成复杂，至今未能逐一检测出其所含成分。对目前国内外常用分析检测米糠油中γ-谷维素的方法进行了分析比较，紫外分光光度法用于粗略测定γ-谷维素含量，高效液相色谱法作为先进手段测定结果较为准确，液质联用、气质联用技术能精确分离检测γ-谷维素所含阿魏酸酯成分，有助于γ-谷维素生理活性的进一步研究。
γ-穀維素是一種重要營養物質，尤其在米糠油中，其含量佔1%~2%，是一種天然抗氧化劑。由于組成複雜，至今未能逐一檢測齣其所含成分。對目前國內外常用分析檢測米糠油中γ-穀維素的方法進行瞭分析比較，紫外分光光度法用于粗略測定γ-穀維素含量，高效液相色譜法作為先進手段測定結果較為準確，液質聯用、氣質聯用技術能精確分離檢測γ-穀維素所含阿魏痠酯成分，有助于γ-穀維素生理活性的進一步研究。

γ-oryzanol is an important nutrient, and the content ofγ-oryzanol in rice bran oil is 1% -2%, which is a natural antioxidant. Since the composition ofγ-oryzanol is complex,its ingredients have not been detected one by one. The current common analysis and detection techniques of γ-oryzanol in rice bran oil at home and abroad were compared. UV spectrophotometer was used for the rough determina-tion ofγ-oryzanol content, high performance liquid chromatography as an advanced means had accurate determination results, and LC-MS and GC-MS could accurately separate and detect the composition of ferulic acids,which contributed to the further study of physiological activities of γ-oryzanol.
