ResumoThe carotenoid composition of Oscillatoria rubescens has been re-examined in a quantitative manner. β-Carotene, zeaxanthin, echinenone (myxoxanthin), myxoxanthophyll and oscillaxanthin were found together with small amounts of cryptoxanthin and a hydroxylated ketocarotenoid whose probable structure is 4-keto-3′-hydroxy-β-carotene (I). The carotenoids of an Athrospira sp., whose systematic position is close to that of O. rubescens, were qualitatively and quantitatively very similar to those of O. rubescens, and the Athrospira sp. can be used as a more convenient source for myxoxanthophyll and oscillaxanthin—the structures of which are not yet established.
