Abstract

Seaweeds are marine macroscopic algae, which play a vital role in marine living organisms. Secondary metabolites (phytochemicals) have been intensively studied as potential therapeutic agents. Brown seaweeds (Phaeophyceae) such as Sargassum latifolium and Turbinaria Ornata were collected in winter season from Dahab red seacoast of Egypt. Sargassum latifolium and Turbinaria Ornata are rich in carbohydrates being44.52 and 40.2 mg/g dry weight, respectively. Sargassum Latifolium recorded a higher protein content of 6.48 2 mg/g dry weight), whereas Turbenaria Ornata reported a higher lipid content being 1.9 2 mg/g dry weight.  Moreover, the phenolic, flavonoids, alkaloids and tannin contents were quantitatively estimated in methanolic extract of algae under study. The Phenolic content was found in a higher amount in Sargassum latifolium being 2.71 ± 0.01 mg of GAE/gm dry wt weight while the Turbinaria Ornata alga recorded a higher content of flavonoids, tannins and alkaloids being41.5 mg quercetin acid – 81.55 mg TAE acid – 3.21 mg GAE acid / g dry weight, respectively. Sargassum latifolium showed a higher antioxidant activity with IC50 being1.9 mg/mL whereas Sargassum latifolium showed a higher antibacterial activity against Escherichia coli and Staphylococcus aureus with an inhibition zone being13±0.024 mm and 15.66±0.3 mm, respectively. Conclusively, these results signify the vital role for those algae in the medical field.
