Descripción

Descripción general

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.

Aplicación

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

Acciones bioquímicas o fisiológicas

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.
