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。

Neoxanthin and fucoxanthin, which have the characteristic structure of 5,6-monoepoxide and an allenic bond, were previously found to reduce the viability of human prostate cancer cells most intensively among 15 dietary carotenoids tested. In the present study, the induction of

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

In order to maximize their use of light energy in photosynthesis, plants have molecules that act as light-harvesting antennae, which collect light quanta and deliver them to the reaction centres, where energy conversion into a chemical form takes place. The
