摘要

Polar orange pigments were extracted from the cultured cells of a marine bacterium, strain PC-6, which was temporarily identified as Flavobacterium sp., and purified by chromatographic methods. The structures of two new carotenoid sulfates, (2R,3S,2'R,3'R)-4-ketonostoxanthin 3'-sulfate (1) and (2R,3R,2'R,3'R)-nostoxanthin 3-sulfate (2) were determined by spectroscopic methods.
