The Pigment, spinochrome F, isolated from the spines of sea urchin HETEROCENTROTUS MAMILLATUS (Linne) (Paipu-uni in Japanese), was proved to be identical with spinochrome C (III), 2-acetyl-3,5,6,7,8-pentahydroxy-1,4-naphthoquinone, on the basis of the spectral data (IR, UV, NMR and Mass) and the results of elementary analyses. Besides spinochrome F, two kinds of pigments were obtained from the spines, and these were confirmed to be identical with spinochrome A (I), 2-acetyl-3,5,6,8-tetrahydroxy-1,4-naphthoquinone, and with spinochrome B, 2,3,5,7-tetrahydroxy-1,4-naphthoquinone, respectively by the spectral data and the analytical results.
