Astaxanthin in the American Flamingo
Nature, 1955THE flamingo, Phoenicopterus ruber, derives from its dietary carotenoids the conspicuous rich pink to red colours of its feathers, tarsal and pedal skin and lower bill-mandible. Captive flamingos gradually lose their rich pigmentation unless appropriate dietary measures are taken. The presumptive role of crustacean carotenoids in supplying pigmentation

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 ...

The reaction kinetics for the hydrolysis of astaxanthin esters and the degradation of astaxanthin during saponification of the pigment extract from the microalga Haematococcus pluvialis were investigated. Different concentrations of sodium hydroxide in methanol were used for the saponification under nitrogen in darkness at ambient temperature (22 ...
