IMPORTANCE Dietary supplements have been proposed as a mechanism to improve health and prevent disease. OBJECTIVE To determine if supplementing diet with long-chain ω-3 polyunsaturated fatty acids or with macular xanthophylls results in a reduced rate of cardiovascular disease (CVD). DESIGN, SETTING, AND PARTICIPANTS The Cardiovascular Outcome Study (COS) was an ancillary study of the Age-R...

Chlorophyll and xanthophyll dyes extracted from a single source of filamentous freshwater green algae (Cladophora sp.) were used to sensitize dye sensitized solar cells and their performances were investigated. A more positive interaction is expected as the derived dyes come from a single natural source because they work mutually in nature. Cell sensitized with mixed chlorophyll and xanthophyll...

1. The interrelations of visual purple, retinene, and vitamin A in the bull frog retina are analyzed in simple experiments, the results of which are presented in a series of automatically recorded spectra. 2. Observations are reported upon the distributions, properties, and concentrations of xanthophyll, vitamin A, and flavine in the pigmented tissues of the eye.

Antisera to the phosphatides phosphatidyl inositol and phosphatidyl choline as well as to the xanthophylls violaxanthin and zeaxanthin were obtained by immunization of rabbits. The phosphatidyl choline antiserum did not give cross reactions with thylakoid membrane glycolipids, nor with phosphatidyl glycerol and phosphatidyl inositol. The antiserum to phosphatidyl inositol also did not react wit...

Xanthophylls, primarily hydroxyland keto-derivatives of β-carotene (such as zeaxanthin, β-cryptoxanthin, canthaxanthin, echinenone and astaxanthin) have powerful antioxidant activity. Due to several positive effects on human and animal health, industrial application of xanthophylls shows an increasing tendency. In our previous study, carotenoid biosynthesis of the β-carotene producing zygomycet...

Carotenoids are bioactive substances in human diet. The aim of the study was to determine β-carotene and xanthophylls in four berries species. An HPLC gradient elution system were used for separation and quantification of the carotenoids. The highest total carotenoid content among the berries studied was found in cloudberry (2840 μg/100g dw), followed by blueberry (2140 μg/100 g). All berries h...
