Bioactivity assessment of selected seaweeds from the Persian Gulf, Iran

Marine algae are known to produce a wide variety of bioactive compounds to be used in pharmaceutical industries. This study aimed to investigate antioxidant and antimicrobial activity, as well as toxicity of algal extracts from some selected seaweeds including Sargassum angustifolium, Cystoseria myrica (Phaeophyta) and Acanthophora muscoides, Chondrophycus papillosus (Rhodophyta). The n-hexane extract of Sargassum angustifolium showed potent toxicity against Artemia franciscana. Moreover, the ethyl acetate and n-hexane extracts of Sargassum angustifolium showed higher reducing power and total antioxidant capacity, respectively. In antimicrobial aspect, the seaweed extracts had the highest antibacterial effect against gram-positive bacteria, Bacillus subtilis, and Staphylococcus aureus. This study revealed the potential toxicity, antioxidant and antimicrobial activity of the studied seaweeds from the Persian Gulf, which make them suitable candidate as ingredients in pharmaceutical industries
