“…Xanthophyll pigments efficiently absorb the blue light and impede the formation of reactive oxygen species in the photoreceptors that helps to defend from light-induced oxidative damage in the retinal pigment epithelial cells [ 29 , 30 ]. These macroalgae pigments show diverse activities such as antioxidant activity, neuroprotective effects and cardiovascular protection [ 31 ].…”

Exploration of seaweeds to unravel their bioactive metabolites from the perspective of wider applications gained substantial importance. The present study was performed to investigate the total phenolic, flavonoid, tannin content, antioxidant activity and antibacterial potential of various solvent extracts of green seaweed Caulerpa racemosa. The methanolic extract showed higher phenolic (11.99 ± 0.48 mg gallic acid equivalents/g), tannin (18.59 ± 0.54 mg tannic acid equivalents/g) and flavonoid (33.17 ± 0.76 mg quercetin equivalents/g) content than other extracts. Antioxidant activity was determined by using 2,2-diphenylpicrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay with different concentrations of C. racemosa extracts. The methanolic extract showed higher scavenging potential in both the DPPH and ABTS activity with the inhibition value of 54.21 ± 1.39% and 76.62 ± 1.08%, respectively. Bioactive profiling was also identified by using Gas chromatography-mass spectrometry (GC-MS) and Fourier transform infrared (FT-IR) techniques. These studies revealed the presence of valuable bioactive compounds in C. racemosa extracts and these compounds might be responsible for antimicrobial, antioxidant, anticancer and anti-mutagenic properties. Major compounds identified in GC-MS were 3,7,11,15-Tetramethyl-2-hexadecen-1-ol, 3-hexadecene and Phthalic acid. In terms of antibacterial activity, C. racemosa has promising antibacterial potential against aquatic pathogens Aeromonas hydrophila, Aeromonas veronii and Aeromonas salmonicida. Further evaluation studies focusing aquatic related aspects would reveal the novel bioproperties and applications of C. racemosa.

“…According to bibliography the presence of fucoxanthin overlaps the presence of other pigments in a macroscopic point of view even though the chlorophyll content is sometimes higher in brown macroalgal species. Other than fucoxanthin, brown macroalgae contain Chl a, Chl c and β-caroten (Cikoš et al 2022). The changes in pigment composition of S. muticum reported here are also substantial; the pigment composition of S. muticum, of which chlorophyll a, chlorophyll c and carotenoids are the major components.…”

Since 2012 Moroccan Atlantic coast have witnessed the introduction of the brown alien seaweed Sargassum muticum with a high invasive potential presenting environmental and economic risks. This study evaluates, for the first time, the effect of seasons and location on biochemical composition of S. muticum. Proteins, carbohydrates, lipids, pigments, minerals, and heavy metals were studied during four seasons from spring 2019 to autumn 2020 in four different sites along the Moroccan Atlantic coast (El Jadida, Saada (SA), Sidi Bouzid (SB), Moulay Abdallah (MA) and Jorf Lasfar (JL)). MA present highest proteins content (12.5% dw) during spring and highest levels of lipids and carbohydrates content during summer (1.8% dw and 41.5% dw respectively). Highest chlorophyll a content was found in JL and MA site with (21.6 and 21.45 mg ml− 1 respectively) during winter. Maximum chlorophyll c and carotenoids was found at SA with (2.27 and 9.71 mg ml− 1respectively) during winter. In all locations and during all seasons, the mineral profile was rich in essential minerals such as Mg, Mn, Zn, Fe, Se and Li. Levels of toxic metals Al and Pb were lower than in previous studies whereas Cd and As turn to be slightly higher than the legislations limits for dry seaweeds. Therefore, in this context, some strategies of S. muticum valorisation should be favoured such as bioenergy, bioplastic or biostimulant over others such as human food and animal feed.

“…Red algae are renowned for their rich content of bioactive polysaccharides, such as carrageenans and agar, which possess anticoagulant, antiviral, and immune-modulating properties. Additionally, red algae contain polyphenols, terpenoids, and other secondary metabolites with potential therapeutic applications [14].…”

Seaweeds, also known as marine algae, have gained attention as a promising source of bioactive compounds with potential applications in drug discovery. This review explores the emerging field of seaweed-based drug discovery and highlights the diverse range of bioactive compounds found in seaweeds, including polysaccharides, phlorotannins, pigments, and peptides. These compounds exhibit various pharmacological activities such as antioxidant, anti-inflammatory, antimicrobial, antiviral, and anticancer effects. Seaweeds have demonstrated particular promise in the areas of cancer research, with certain species showing potent antitumor properties. Additionally, their anti-inflammatory, antimicrobial, and neuroprotective potential has captured scientific interest in the treatment of chronic diseases and neurodegenerative disorders. However, challenges related to compound identification, extraction methods, scalability of seaweed cultivation, and understanding the mechanisms of action still need to be addressed. As researchers employ advanced technologies and dive deeper into the chemical composition of seaweeds, the untapped potential of these marine organisms in drug discovery awaits further exploration and holds significant promise for future therapeutic advancements.
