Abstract
Polar orange pigments were extracted from the cultured cells of marine bacterium strain SD-212 and purified by chromatographic methods, The structures of two new trihydroxy-keto-carotenoids, (2R,3S,3'S)-2-hydro xyastaxanthin (1) and (2R,3S,3'R)-2-hydroxyadonixanthin (2) were deter mined by means of spectral methods, Known carotenoids (3S,2'R,3'R)-ery throxanthin (3), 3,2',3'-tetrahydroxy-beta,beta-carotene-4,4'-dione (4 ), 'R)-2,3,2',3'-tetrahydroxy-beta,beta-caroten-4-one (5), (3S,3'S)-as taxanthin (6), and (3S,3'R)-adonixanthin (7) were also isolated.
