Descripción

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.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
