p. 193 - 204 SUR LES PIGMENTS VERTS DES PILIDES DES MOLLUSQUES BIVALVES MYTILUS GALLOPROVINCIALIS LMK. ET MYA ARENARIA I.A. Molnar 1), Camena Panteli 1) et Maria Mirza 2) 1)Institut de Recherches Chimiques-Pharmaceutiques Bucuresti 2)Institute Roumain de Recherches Marines Constanta Abstract The presence of liposolubles green prigments from Mytilus galloprovincialis (seven) and Mya arenaria (six) was demonstrated. Absorption spectra (CHCl3) of these pigments presented absorption bands at 505-510; 537-540; 608-612 and 668 nm (Mytilus galloprovincialis); 500-505; 535; 610-615 and 668-670 nm (Mya arenaria). Seasonal changes of the green pigments level were determined for Mytilus galloprovincialis.
