General description
Zeaxanthin is a carotenoid that belongs to the group of xanthophylls. A dihydroxy derivative of β-carotene, it is found in vegetables and fruits, besides the eyes and skin of humans. It is known to show anti-oxidant, anti-inflammatory, anti-apoptotic, and neuroprotective properties.
Application
The analytical standards can also be used as follows:
- Optimization of an ultrasonic-assisted extraction procedure for obtaining zeaxanthin and lutein from corn gluten meal samples for their determination by high-performance liquid chromatography-UV-Visible detection
- Simultaneous quantification of five carotenoids and two chlorophylls from soybean flour samples by reversed-phase high-performance liquid chromatographic (RP-HPLC) method combined with UV-Vis detector
- Multi-residue analysis of carotenoids and apocarotenoids in intact human blood samples by supercritical fluid extraction and supercritical fluid chromatography-atmospheric pressure chemical ionization-triple quadrupole mass spectrometry detection (SFE-SFC-APCI/QqQ/MS)
- High-performance liquid chromatography-diode array detector (HPLC-DAD) method-based determination of carotenoids in marigold flower and food supplement samples
- Profiling of carotenoids and their isomers in different plant tissue samples by high-performance liquid chromatography (HPLC) using a C30 column and photodiode array (PDA) detection
Biochem/physiol Actions
Carotenoid pigment that contributes to the color of paprika. Zeaxanthin accumulates within the eye retina and is thought to decrease the incidence of macular degeneration.

Carotenoids are among the most abundant natural pigments available in nature. These pigments have received considerable attention because of their biotechnological applications and, more importantly, due to their potential beneficial uses in human healthcare, food processing, pharmaceuticals and cosmetics.

Researchers have suggested that omega-3 polyunsaturated fatty acids from oily fish (long-chain omega-3 (LCn3), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)), as well as from plants (alpha-linolenic acid (ALA)) benefit cardiovascular health. Guidelines recommend increasing omega-3-rich foods, and sometimes

The food matrix in which carotenoids are found affects their bioavailability. Lutein and zeaxanthin are abundant in egg yolks and accumulate in the macular region of the retina, where they may affect visual function. We sought to determine whether plasma
