摘要：

Structure I, previously assigned by Kuhn and Grundmann2 2 R. Kuhn and C. Grundmann, Ber. 67, 339 (1934). to rubixanthin, is supported by further spectroscopic and chemical data. Except for the melting point and minor deviations in the NMR-spectra and CD-curves, identical data were obtained for gazaniaxanthin. Our observations are in agreement with the recent conclusion by Brown and Weedon3 3 B.O. Brown and B.C.L. Weedon, Chem. Commun. 382 (1968). that rubixanthin is all-trans I and gazaniaxanthin the corresponding 5′,6′-cis-isomer. Our comparative NMR-studies provide support for placing the hydroxyl group in the 3-position. © 1970.
