Abstract
β-Carotene (21.1%), isorenieratene (5.7%), isorenieracistene (23.1%), trikentriorhodin (9.2%) and a new carotenoid (13.4%) were isolated from the sea sponge, Suberites sericeus.
The structure of the new carotenoid has been established to be 7, 7'-dicis-φ, φ-carotene by chemical and physical methods including 1H-NMR, IR, and mass spectra.
It is interesting from biosynthetic point of view that S. sericeus possesses relatively high contents of 7-cis carotenoids which is rare in nature.
