Algal Carotenoids. XIV. Structural Studies on Peridinin. Part 1. Structure Elucidation.

Abstract
The characteristic pigment of the dinoflagellates, peridinin, was studied. Based on detailed spectroscopic and chemical evidence peridinin has been assigned the structure 5'',6''-epoxy-3,5,3''-trihydroxy-6,7-didehydro-5,6,5'',6''-tetrahydro-12,13,20-trinor-.beta.,.beta.-caroten-19'',11''-olide 3-acetate.
