Astaxanthin in the Cedar Waxwing
Science, 1963The pigment on the secondary feathers of the cedar waxwing ( Bombycilla cedrorum ) is deposited as an amorphous layer upon a supporting medullary structure. The pigment was extracted with alkali and analyzed by chromatographic and spectrophotometric methods.

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

The biosynthesis of astaxanthin
International Journal of Biochemistry, 1970Abstract A new keto carotenoid was isolated from goldfish ( Carssius auratus ) which was shown to be a 3-hydtoxy-3',4'-diketo-α-carotene. The name α-doradecin is proposed for the keto compound and doradexanthin for the esterified carotenoid, or mono keto compound. The carotenoids β-carotene, letein, α-doradecin, β-doradecin (3-hydroxy-3',4'-diketo-β-

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 ...
