Bioactive Compounds and Antioxidant Activities of Brown Algae Collected from the Shores of the Egyptian Seas
2021
Overview
Brown algae (BA) belongs to the group Heterokontophyta, a large group of eukaryotic organisms distinguished most prominently by having chloroplasts surrounded by four membranes. In Egypt, BA is naturally spread over large areas of marine beaches. The present study aims to determine the chemical composition and bioactive compounds in BA samples collected from the shores of the Egyptian Seas. Also, biological activities of the same BA samples extracts will be studied. Results indicated that carbohydrates were the largest compound (60.59%) followed by Dietary fiber (48.78 %), ash (19.45%), crude fiber (7.14%), total protein (4.02%) and crude fat (0.82%). Also, polysaccharides were the largest compound followed by phenolics, tannins, carotenoids and flavonoids. β-carotene assay (BCA) indicated that ethanol extract (EtE) recorded the highest antioxidant activity followed by methanol extract (MeE) and water extract (AqE). The values of EtE extract are coming well i.e. closing to the line of 50 mg α-tocopherol followed by MeE and AqE, respectively. Also, AqE possessed the highest free radical scavenging activity (FRSA). For Half-maximal inhibitory concentration )IC50(, the AqE, EtE and MeE recorded 19.92, 10.41 and 12.52 μg/mL, respectively. The IC50 of BHT (standard) was 7.78 μg/mL. The BCA and FRSA of different tested extracts and standards were in the following order: standards (BHT/ α-tocopherol) >EtE >MeE >AqE. In conclusion, Brown algae extracts (BAE) contain several classes of phytochemicals with other compounds that are responsible for different biological activities including antioxidant and radical scavenging activities. Therefore, we recommended brown algae powder and/or extracts to be included in daily diets, drinks, food supplementation and pharmacological formulae.
