This paper reports the results of flavonoids determination expressed in rutin from marine algae. For this purpose, rutin and rutin AlCl3 complexes were spectrophotometrically studied in three domains of ligand concentrations: ligand Crut=1.34-6.7mg/L, 4-20mg/L and 2-32mg/L. The precision, accuracy, specificity, and the quantification limit of the method were verified. The calibration curve trac...

Ethanolic crude extracts from seven marine algal species belong to Clorophyceae (Cladophora glomerata, Enteromorpha linza, Ulva rigida), Phaeophyceae (Cystoseira barbata, Padina pavonica) and Rhodophyceae (Corallina officinalis, Ceramium ciliatum) from the coast of Vona, Turkey were evaluated in vitro for the antibacterial and antifungal activity of six bacteria and two fungus with the paper di...

Sampling of sublittoral macroalgal assemblages was carried out in 1982 and 1999 along the coast of Catalonia (Northwestern Mediterranean, Spain) in order to study long-term changes in species composition. Ordination analysis revealed significant differences in species composition and abundance between the two study periods. The number of stations with indicators of eutrophication, such as speci...

The results of a study on morphological features and reproductive phenology the brown alga Cystoseira foeniculacea f. tenuiramosa (Ercegović) A. Gómez Garreta, M.C. Barceló, M.A. Ribera & J. Rull Lluch from marine lagoon Strunjan (Gulf Trieste), are reported. Based monthly samplings carried out during one year period, it was observed that this species shows considerable seasonal variati...
