应用
新黄素可用作参考标准品，以采用高效液相色谱法（HPLC）测定三角褐指藻提取物的酚含量和抗氧化活性。
生化/生理作用
新黄素是一种等位叶黄素，并且是菠菜和大麦叶等植物中主要的类胡萝卜素之一。橄榄油中也可以找到微量的这种色素。新黄素以两种异构体存在，即反式-新黄素和9′-顺式-新黄素。它也是脱落酸的前体。它可通过提供一般抗氧化活性产生光保护作用。新黄素具有凋亡和抗增殖作用。

Light is a paramount parameter driving photosynthesis. However, excessive irradiance leads to the formation of reactive oxygen species that cause cell damage and hamper the growth of photosynthetic organisms. Xanthophylls are key pigments involved in the photoprotective response of plants
