Abstract

SARGASSUM latifolium is an edible brown alga collected from the red seashore in Egypt during autumn. This research aimed to investigate the physicochemical properties and biogenic molecules of S. latifolium. The optimal physicochemical properties of red seawater were a moderate temperature (24°C), salinity (40.12%), hydrogen ion concentration (7.8), dissolved oxygen (7.37mg/L), a slightly alkaline pH, a slightly elevated biochemical oxygen demand (1.8mg/L), and an electrical conductivity of 53.67mmhos/cm. S. latifolium’s biochemical composition is rich in carbohydrates (45.52mg/g dry weight) and low in protein (6.38mg/g dry weight). S. latifolium contained 89.23% and 23.37% moisture and ash, respectively. The bioactive compounds in an aqueous crude extract of S. latifolium separated between 200 and 400nm, as shown by UV scan analyses. The FT-IR analysis of S. latifolium revealed numerous functional groups, including -OH, -NH, -CH, -COOH, CO, and C–C. The resulting aqueous extract of S. latifolium contained steroids, terpenoids, flavonoids, phenols, coumarins, and quinones.
