Abstract
Marine organisms are considered as a treasure for discovery of bioactive metabolites. Seagrasses provide food and habitat for other marine organisms. They are widely distributed in tropical and subtropical regions. Seagrass Thalassodendron ciliatum (Forsk.) den Hartog is a very common seagrass species in the Red Sea. Several studies have proved its antioxidant, anti-inflammatory and antimicrobial potentials. Gas Chromatography-Mass spectrometry Analysis was performed for identification of existed phytochemicals. Herein, it is the first reported study explaining the lipoidal matter of n-hexane fraction of T. ciliatum using GC-MS technique. The obtained data revealed presence of saturated and unsaturated- long chain- fatty acids; tetradecanoic acid, eicosanoic acid, 9,12-hexadecadienoic acid and 8,11,14-eicosatrienoic acid, in addition to other volatile compounds; 1-heneicosanol, 2,6-bis (1,1-dimethylethyl) phenol and 1-tridecanol. These compounds were previously assessed for their antibacterial, antifungal, antimicrobial and anti-inflammatory bioactivities. So, the previously reported antioxidant, anti-inflammatory and antimicrobial activities of Thalassodendron ciliatum may be attributed to these identified compounds.
Highlights
The marine environment (>70% of the planet's surface) possesses unique biological and chemical characters that play a vital role in discovery of many drug leads
The Red Sea is considered as a precious natural source of bioactive compounds because of its distinctive features; lack of any river drainage, great marine organisms’ biodiversity, and seasonal fluctuations of air and water temperatures
Goda et al reported in Red Sea marine organisms besides, other metabolites of diverse chemical classes (El-Ezz et al, 2017)
Summary
The marine environment (>70% of the planet's surface) possesses unique biological and chemical characters that play a vital role in discovery of many drug leads. Many marine-living organisms are soft bodied and/or sessile They have developed toxic secondary metabolites to defend themselves against predators (Eltamany, 2015). Goda et al reported in Red Sea marine organisms besides, other metabolites of diverse chemical classes (El-Ezz et al, 2017). This biodiversity ensures presence of different classes of secondary metabolites that manifested beneficial biological activities. To the best of our knowledge, few previous studies were reported concerning chemical investigation of T. ciliatum. It is the first reported one explaining the lipoidal matter of T. ciliatum using GC-MS technique
