title: New C(40)-carotenoid acyl glycoside as principal carotenoid in Salinibacter ruber, an extremely halophilic eubacterium.
abstract: The principal (>96% of total) carotenoid in the novel, extremely halophilic eubacterium Salinibacter ruber, here called salinixanthin (1), has been assigned the structure (all-E,2'S)-2'-hydroxy-1'-[6-O-(13-methyltetradecanoyl)-beta-D-glycopyranosyloxy]-3',4'-didehydro-1',2'-dihydro-beta,psi-caroten-4-one by spectrometric (vis, EIMS, (1)HNMR, CD, GCMS) and chemical methods.
