“…In a study conducted with avocado (Persea americana), young leaves, fully expanded leaves, and old leaves had xanthophyll pigment concentrations of 138.5, 112.9, and 239.1 mmol mol −1 chlorophyll, respectively [9]. In another study, the seasonal progression of photoprotection responses in different aged savin juniper plants (Juniperus sabina) under shade and sun conditions was evaluated [18]. The results showed that although lutein may play an important role in dissipating excess energy, there was also a large seasonal effect on its concentrations that appeared to have little to do with irradiance.…”

Xanthophylls, such as lutein and zeaxanthin, have several functions in both plants and humans, including detoxification of oxidants (reactive oxygen species (ROS) and other radicals), maintenance of the structural and functional integrity of biological membranes, and photoprotection from intense light damage. The objective of the present study was to investigate the lutein and zeaxanthin content of 21 species of plants from a very humid premontane forest in Colombia during both dry and rainy seasons. The plants were selected based on being voluntarily eaten by laying hens under free-range conditions. Lutein and zeaxanthin were identified and quantified by high-performance liquid chromatography (HPLC). The results showed that all plants tested contained lutein, at levels ranging from 65.7 to 350 µg/g. Zeaxanthin levels were much lower (2.2 to 26.2 µg/lg) and were detected in only 5 of the 21 plants analyzed. Given that the lutein content of the plants tested in the present study was found to be comparable to that reported in marigold flowers (4–800 µg/g), it is possible that these plants can be used as a source of lutein in free-range laying hen production systems.

Lutein, [(3R,3′R,6′R)-β,ε-carotene-3,3′-diol], is a C40 hydroxyl carotenoid. Its chemical structure is based on an unsaturated polyene chain skeleton, and there are one ε-ring and one β-ring on both sides of the skeleton, with a hydroxyl group on the 3′ site of each ring. Lutein is one of the important lipophilic isoprenes from mainly plants and algae. The wide range of sources makes the study of lutein quite comprehensive. The biosynthetic pathway and biochemical activities of lutein have been extensively studied and revealed. Lutein has been extensively studied for its important bioactivity, including for use in functional foods and medicines for brain health, eye-related diseases, skin health, and cancers. This review of lutein summarizes the major studies on bioactivity, metabolism, stability, digestive absorption, lutein delivery systems, and biotechnology.
