一般說明

β-生育酚是脂溶形式的维生素E,具有抗氧化、抗炎、抗细胞增殖和抗癌特性。

應用

该分析标准品溶液可用于以下应用:
  • 通过超高效液相色谱(UHPLC)和荧光检测在液液萃取(LLE)后同时测定人血清样品中的维生素A和所有四种生育酚异构体
  • 通过液相色谱电喷雾电离/多级质谱(LC-ESI-MS/MS)进行四种不同小麦品种中麦草和麦粒样品的维生素B(B1、B2、B5和B9)和维生素 E (α-生育酚、β-生育酚、α-三烯生育酚和β-三烯生育酚)的多残留分析
  • 通过非水反相高效液相色谱(NARP-HPLC)和大气压化学电离-串联质谱(APCI-MS/MS)检测分离和评估沟美洲山核桃栽培样品中的四种生育酚和四种三烯生育酚
  • 通过化学计量法辅助的优化高效液相色谱(HPLC)和荧光检测方法分析不同冷榨油样品以检测和定量测定八种母育酚同系物
  • 开发和确定正相高效液相色谱(NP-HPLC)方法,该方法和荧光检测一起使用可以同时测定芝麻油样品中的四种生育酚和四种木酚素。

As integral regulators in plant development and stress response, microRNAs (miRNAs) themselves need to be tightly regulated. Here, we show that tocopherols (vitamin E), lipid-soluble antioxidants synthesized from tyrosine in chloroplasts, positively regulate the biogenesis of miRNAs. Tocopherols are required
