Aplysia oculifera

Extracts of A. dactylomela are rich in other organic metabolites as has been demonstrated earlier. Gopichand et al, 552) isolated four new halogenated acetylenic ethers (864-867) from the digestive glands. These ethers which are fatty acid derived were two isomeric pairs named (3 )-12-epiobtusenyne (864), 12-677/-obtusenyne (865), (S )- and (3Z)-dactomelyne (866 and 867), respectively. Another isomeric pair, E)-and (Z)-ocellenyne (868 and 869), has been obtained from Aplysia oculifera (559). No biological activity has been described for any of these compounds.
