“…near than twice less of those obtained for glycolipids and phospholipids. According to our previous results (Terme et al, 2017), the glycolipid and phospholipids fractions represented up to 90% of the lipid fraction from this seaweed. Therefore, the supercritical carbon dioxide is a good method to extract a free radical scavenging fraction from the seaweed S. muticum.…”

“…In this case, the addition of ethanol in sc-CO 2 produced a less active fraction. However, no significant difference was observed by increasing the amount of ethanol despite an increase of the glycolipid quantity (Terme et al, 2017). This result suggests that sc-CO 2 did not efficiently extract antioxidant glycolipids from S. chordalis.…”

“…This result suggests that the composition of the neutral lipid fractions is the same whatever the extraction method. As the quantity of neutral lipid extracted increases with the addition of ethanol (Terme et al, 2017), the combination of sc-CO 2 and ethanol seems to be the best way to obtain antiradical compounds from the neutral lipid fraction. For glycolipids, the best activity was obtained with the CM extraction (49.3 ± 1.6% of scavenging).…”

“…The most active fraction was obtained with sc-CO 2 þ ethanol 8% with a half more activity than the lipids extracted with CM. As the content of phospholipids decreased when ethanol was added to sc-CO 2 (Terme et al, 2017), 8% ethanol in sc-CO 2 might extract phospholipids with a greater free radical scavenging activity. Phospholipids with polyunsaturated fatty acids were probably extracted with selectivity as they are known to have antioxidant properties (Henry et al, 2002).…”

“…The lipid class fractions were prepared according to Terme et al (2017). Briefly, S. chordalis (Rhodophyta, Gigartinales, Solieriaceae) and S. muticum (Phaeophyceae, Fucales, Sargassaceae) were collected on the littoral area of Saint Gildas de Rhuys (47°29 0 34.0 00 N 2°49 0 51.0 00 W, Atlantic coast, France) in October 2017 and in July 2014, respectively.…”

In vitro antioxidant activities of the lipid fractions from two selected seaweeds, Solieria chordalis and Sargassum muticum were investigated according to the extraction methods. The activity of neutral lipids, glycolipids and phospholipids, thanks to extraction by chloroform/methanol (1/1 v/v; CM) mixture, pure supercritical carbon dioxide (sc-CO2), supercritical carbon dioxide with 2% of ethanol (sc-CO2 + EtOH 2%) and supercritical carbon dioxide with 8% of ethanol as co-solvent (sc-CO2 + EtOH 8%), were studied using DPPH radical scavenging assays. All the lipid classes demonstrated a free radical scavenging activity at the concentration of 1 mg/ml. The best scavenging activity (86.6 ± 5.7%) was obtained when the neutral lipid fraction was extracted from S. chordalis with a CM mixture. The neutral lipid fraction extracted with sc-CO2 showed a lower activity than those obtained with solvents. However, the addition of ethanol in sc-CO2 did not affect the antioxidant activity of neutral lipids fixed at around 16% of radical scavenging. For S. muticum, the activity of glycolipids (50.9 ± 0.8%) and phospholipids (48.4 ± 1.6%) obtained with sc-CO2 were twice as large as that of fractions obtained with CM, 29.6 ± 3.4% and 28.0 ± 4.2%, respectively. The activity of neutral lipids did not change with the extraction method with around 25% of radical scavenging. This is the first report of free radical scavenging activity of lipid classes obtained by supercritical carbon dioxide extraction from seaweeds.

Algae are organisms with an enormous biodiversity and contain manifold fatty acid molecular structures and ratios. This chapter presents information about the structure and distribution of fatty acids in algae whether microalgae or macroalgae. The parameters affecting lipid and fatty acid contents as well as distribution are also discussed. Methods for isolation and purification of fatty acids from algae to obtain highly pure fatty acid or fatty acid fractions with good overall yields are presented. Algal fatty acids are known as sources of bioactive compounds for health promotion and wellness. Lipid fractions and fatty acids act as actives or additives for cosmeceutical applications. For health promotion, preventive effects of n-3 polyunsaturated fatty acids on cardiovascular disease, metabolic syndrome and cancer are discussed. The role of n-3 fatty acids in cancer therapy and antiviral activities of lipids are also exposed. Furthermore, potential commercial application domains and concepts are discussed in this chapter.

Marine macroalgae are emerging as sustainable and healthy food, and a source of lipids with nutritional and bioactive properties. Nonetheless, the lipidome of macroalgae is little explored compared to other photosynthetic organisms. Most of the literature is devoted to the analysis of fatty acid (FA) from macroalgae, because of they are a source of long-chain omega-3 and omega-6 polyunsaturated FA, which can be used as an alternative to fish oil. However, FA occurs mostly esterified in other lipids, such as polar lipids, that still overlooked. The data published on the study of polar lipids (phospholipids, glycolipids, betaine lipids) pinpoint their remarkable characteristics and bioactive properties which mainly remain unexplored. The lipidome of macroalgae seems to be species-specific, while some lipid classes appear to be characteristic of phyla. Lipidome plasticity of macroalgae is verified to change under abiotic and biotic factors which may modulate the functionality and add-value of the biomass. This biochemical plasticity represents an advantage to obtain ingredients for target applications and niche of markets. This review provides an overview on macroalgae lipidome characterization, addressing analysis workflow based on liquid chromatography coupled to mass spectrometry, and discussing the bioactive properties and biotechnological applications of macroalga lipids. Practical Applications: The current state of the art on marine macroalgae lipidomics is reviewed, including the lipid characterization using modern liquid chromatography-mass spectrometry, the distribution of polar lipids by macroalgae species and phylum, their bioactive properties, and potential biotechnological applications. In a time of increasing awareness of sustainably produced marine resources, the lipids from macroalgae are still underexplored. This review provides information for smart valorization of macroalgae as source of add-value lipids contributing to the development of blue bioeconomy.
