| 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-atmospheri • 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. |
| 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. |
