Abstract

A new trihydroxyl carotenoid has been isolated from the yeast Rhodotorula aurantiaca (Saito) Lodder C.B.S. 317 and identified as 2-hydroxyplectaniaxanthin (3′,4′-didehydro,1′,2′-dihydro-β, ψ-caroten-2,1′,2′-triol). Its m.p., partition coefficient, Rf, extinction coefficient, ms and NMR spectra are reported. Since the hydroxyl group at C-2 of the β-ionone ring is unusual, a possible mechanism for the biosynthesis of this carotenoid has been proposed. © 1973.
