| Popis: | 1. 1. A blue-green pigment has been isolated from shells of the trochid Monodonta turbinata . 2. 2. The pigment behaved as a highly polar compound and gave the Gmelin reaction. 3. 3. The absorption spectrum of the pigment in methanolic HCl showed maxima at 630, 363 and 315 mμ and inflexions at 405 and 270 mμ. The zinc complex of the pigment exhibited yellow-green fluorescence in u.v. light. On oxidation with iodine it showed a shoulder at 660 mμ extending to 610 mμ in the absorption spectrum. 4. 4. It is suggested that the pigment is a biladiene probably related to the bilatriene present in the foot of M. turbinata . |
