Abstract
Macroalgae produce a wide variety of chemically active secondary metabolites. Brown seaweed; Sargassum vulgare and its associated seaweeds were collected from Hurghada Red sea coast of Egypt. Optimal physicochemical properties; slightly alkaline; low turbidity, moderate temperature and available nutrient content of saline water produced massive growth of S. vulgare (53% covering percentage) during autumn (2018). Heavy metals accumulation inside the investigated seaweed S. vulgare was within the usually range. The associated macroalgal species with S. vulgare are belonging to 9 genuses, 12 species. Chromatography, mass spectrophotometry (GC/MS) analysis revealed the presence of Twenty five bioactive compounds. The major phytochemical constituents in the chloroform extract of S. vulgare are n-Hexadecanoic acid 28.29 %, Heptacosane 8.04 %, trans-13-Octadecenoic acid 5.50 %, Oleic Acid 4.24 %, Palmitoleic acid 3.56 % and Hexadecanoic acid, ethyl ester 3.30 %.
