Abstract

From a mixture of the pigments of the sea urchinStrongy locentrotus dröebachiensis in additionto the known spinochromes A C D and E we have isolated a binaphthoquinone and its anhydro derivative On the basis of13C NMR spectra the position of the ethylidene bridge symmetrically binding the two naphthazarin fragments of the binaphthoquinone has been definnitely established and the structure of this compound has been determined as ethylidene66′bis237trihydroxynaphthazarin
