应用

(+)-δ生育酚用作参考物质，通过高效液相色谱法（HPLC）将其从油中提取。也作为标准品，通过反相高效液相色谱法，定量大豆中的 δ-生育酚。

生化/生理作用

生育酚 (TCP)（维生素 E）是一系列（α、β、γ 和 δ）的手性有机分子，它们的色满诺环的酚部分甲基化程度不同。生育酚是脂溶性抗氧化剂，保护细胞膜免受氧化损伤。α-生育酚是智人优先吸收的生育酚形式。各种生育酚的同分异构体和类似物在体内具有相反和不同的调节活性。
生育酚（TCP）（维生素E）是一系列（α, β, γ 和 δ）手性有机分子，这些有机分子色原烷醇环苯酚部分的甲基化程度不同。生育酚是脂溶性 抗氧化剂，可保护细胞膜免受氧化损伤。δ-T在8位甲基化。具有抗癌特性。δ-T参与由活性氧物质引发的促炎症反应。它降低脂质积累，促进神经元分化。δ-T还具有抗血管生成和利钠剂活性。
