Purification and structural characterization of compounds isolated from Cystoseira abies-marina

6th Spanish-Portuguese-Japanese Organic Chemistry Symposium, Lisboa, de 18 a 20 de Julho de 2012 (Poster Communication).

Although the Azores archipelago is rich in algal communities, only two papers have been published concerning the nutritional and pharmacological potential of this resource in the Azorean sea.[4,5,6] As a brown alga Cystoseira abies-marina grows abundantly in the coast of these islands and has a great resistance to predation, which indicates the presence of potential active compounds[7], we have investigated its secondary metabolites. We report herein isolation and structure elucidation of several compounds from Cystoseira abies-marina, collected at Mosteiros S. Miguel. The structures of the compounds were established by 1D (1H, 13C, DEPTs) and 2D (COSY, HSQC HMBC, NOESY) NMR techniques as well as HRMS.
