Synthese der (3S,4R,3'S,4'R)- und (3S,4S,3'S,4'S)-Crustaxanthine sowie weiterer Verbindungen mit 3,4-Dihydroxy-β-Endgruppen

Starting from 3, the enantiomerically pure title compounds were synthesized in eight steps.Spectra and HPLC systems are presented that allow a distinction between these isomers.

CAROTENOIDS OF THE ASCIDIAN Halocynthia aurantium

It has been established that the main components of the carotenoid fraction of an extract of Halocynthia aurantium are astaxanthin and diatoxanthin, the latter possessing a weak antioxidant activity.No prenylated hydroquinones, which are characteristic for colonial species of ascidians were detected in the four species of solitary ascidians from the Sea of Japan investigated.
