| 中文摘要: |
| 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。 |
| 英文摘要: |
| γ-oryzanol is an important nutrient, and the content of γ-oryzanol in rice bran oil is 1% -2%, which is a natural antioxidant. Since the composition of γ-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 determination of γ-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. |
