Astaxanthin diferulate as a bifunctional antioxidant
Free Radical Research, 2014Astaxanthin when esterified with ferulic acid is better singlet oxygen quencher with k2 = (1.58 ± 0.1) 10(10) L mol(-1)s(-1) in ethanol at 25°C compared with astaxanthin with k2 = (1.12 ± 0.01) 10(9) L mol(-1)s(-1). The ferulate moiety in the astaxanthin diester is a better radical scavenger than free ferulic acid as seen from the rate constant of ...

Determination of astaxanthin and canthaxanthin in salmonid
European Food Research and Technology, 2005Total carotenoid (astaxanthin, cantaxanthin) content were determined in 60 traditionally cultured salmons (ICL, N1CL, N2CL) (Salmo salar), 10 natural salmons (NWL) (S. salar), 20 ecological cultured salmons (IECL) (S. salar), 20 ecological cultured rainbow trouts (NECR) (Oncorhynchus mykiss), 20 traditional cultured rainbow trouts (NCR) (O.

Astaxanthin has great potential commercial value in the feed, cosmetics, and nutraceutical industries due to its strong antioxidant capacity. In this study, the Escherichia coli strain CAR026 with completely balanced metabolic flow was selected as the starting strain for the production of astaxanthin.

Astaxanthin in the Muscle of Cod
Nature, 1956ASTAXATHIN is probably the most common pigment of marine organisms. It has been found in a variety of species from unicellular algae to fish; it is particularly the typical pigment of the crustaceans.

Astaxanthin (ATX) protects against oxidative stress, various diseases, and age-related degeneration. It is metabolized primarily by hepatic cytochrome P450 1A1 and 1A2 in rats. However, because the free form of ATX is not water-soluble and has low bioavailability, prodrug ATX has been developed to improve its solubility.

Astaxanthin Production from Microalgae
2020Astaxanthin is commercially sold as a pigment for animal feed and as an antioxidant for the nutraceutical sector. Astaxanthin is predominantly manufactured synthetically from petrochemicals but is also obtained from the chlorophyte Haematococcus pluvialis (Haematococcus lacustris). The petrochemical-derived synthetic alternative has conventionally been

Let astaxanthin be thy medicine
PharmaNutrition, 2015Abstract Astaxanthin is known as a “marine carotenoid” and occurs in a wide variety of living organisms such as salmon, shrimp, crab, and red snapper. Astaxanthin antioxidant activity has been reported to be more than 100 times greater than that of vitamin E against lipid peroxidation and approximately 550 times more potent than that of vitamin E for

Antioxidant Activities of Astaxanthin and Related Carotenoids
Journal of Agricultural and Food Chemistry, 2000The antioxidant activities of astaxanthin and related carotenoids have been measured by employing a newly developed fluorometric assay. This assay is based on 4,4-difluoro-3,5-bis(4-phenyl-1, 3-butadienyl)-4-bora-3a,4a-diaza-s-indacene (BODIPY 665/676) as an indicator; 2,2'-azobis-2,4-dimethylvaleronitrile (AMVN) as a peroxyl radical generator; and 6 ...
