“…Improved yield achieved by UAE in comparison to CE is attributed to the bubble cavitation phenomenon generated by ultrasonic waves [75], that was previously observed in fucoidan extraction from Sargassum witghtii [70], Undaria pinnatifida [76] and laminarin extraction from A. nodosum and Laminaria hyperborean [75]. No statistical difference between UAE and CE was reported in fucoidan extraction from N. zanardinii [64] and Fucus evanescens [77], while Okolie et al [65] reported significantly higher yield by CE (11.9%) than by UAE (4.56%) and also no statistical differences between UAE, MAE and EAE.…”

“…Regarding sulfate content there was no unique trend among different authors, obtained by UAE in comparison with CE, since some reported higher sulfate concentration obtained by UAE [71], some similar [70] and some even lower [65]. Fucoidan extracted by UAE (22.97%) had lower sulfate content than the one extracted by EAE (29.6%) but higher than UAE-EAE (21.78%) [74].…”

“…Alboofetileh et al [64] found no significant difference in fucose and uronic acid concentration but galactose content was slightly increased by UAE. However, destructive effect of ultrasound on fucose structure caused slight reduction of fucose concentration in UAE (23.72%) compared to HWE (26.21%) [70]. UAE demonstrated to be more efficient in extraction of higher MW fucoidan [64,65,71] and laminarin [75] then CE, MAE, PLE, EAE and UAE-EAE.…”

“…Among the novel techniques, UAE is the most practical for the industrial level because of its simplicity, faster extraction rate, increased yield as well as reduced cost and processing time [70]. UAE can also be combined with other non-conventional technologies, such as enzymatic processing [71] or MAE [64].…”

“…Considering antioxidant activity of APS extracts, Hanjabam et al [70] reported lower DPPH radical scavenging activity and reducing power along with higher metal chelating activity of fucoidan extracted by UAE in comparison to CE. Laminarin extracted from L. hyperborea and A. nodosum by UAE using acid as a solvent had the highest DPPH activity, 87.58% and 93.24% respectively [75].…”

Over the years, brown algae bioactive polysaccharides laminarin, alginate and fucoidan have been isolated and used in functional foods, cosmeceutical and pharmaceutical industries. The extraction process of these polysaccharides includes several complex and time-consuming steps and the correct adjustment of extraction parameters (e.g., time, temperature, power, pressure, solvent and sample to solvent ratio) greatly influences the yield, physical, chemical and biochemical properties as well as their biological activities. This review includes the most recent conventional procedures for brown algae polysaccharides extraction along with advanced extraction techniques (microwave-assisted extraction, ultrasound assisted extraction, pressurized liquid extraction and enzymes assisted extraction) which can effectively improve extraction process. The influence of these extraction techniques and their individual parameters on yield, chemical structure and biological activities from the most current literature is discussed, along with their potential for commercial applications as bioactive compounds and drug delivery systems.(APS) is determined by algae species however it is also influenced by other factors causing inter-species variation, e.g., growth location and harvesting season [8]. Vast structural variation between the APS therefore presents a challenge in terms of pre-treatments application, extraction techniques and optimization, characterization of isolated fractions and determination of their biological properties.Chemical structure and yield of APS isolated from marine macroalgae by conventional extraction (CE) techniques can be affected by various experimental conditions (pH, time, temperature, pressure, particle size, solvent, sample to solvent ratio, agitation speed etc.). In addition, different advanced techniques such as microwave assisted extraction (MAE), ultrasound assisted extraction (UAE), pressurized liquid extraction (PLE), enzyme-assisted extractions (EAE) are assessed and applied for APS extraction [9][10][11].In general, the chemical structure of polysaccharides determines its physical, chemical and biochemical properties as well as its biological activities [12]. Several studies have reported that their biological activity is strongly associated with their chemical structure [9]. Due to very complex mechanisms that are affected by many factors, the correlation between polysaccharide structure and biological activity is still not sufficiently clarified.In order to improve isolation of APS, pre-treatments are usually applied to the algal biomass prior to the extraction process with the two aims: (i) to prevent co-extraction of interfering bioactive compounds with similar solubility; and (ii) to disrupt cell walls and improve mass transfer of APS into extraction solvent. The first type of pre-treatments is therefore used to remove compounds which are highly bound to the APS such as proteins, phenols and lipids, as well as mannitol and chlorophyll [13]. For that purpose, the application of various pr...

In this study, fucoidan was extracted from the Vietnamese brown seaweed Sargassum mcclurei by ultrasound -assisted extraction method (UAE) using ethanol as a solvent. The effects of single factors on total polysaccharide (TPS) content were then investigated, followed by the screening of main factors affecting TPS content based on their effect sizes and p-values in analysis of variance. The response surface methodology using the Box-Behnken design was applied to investigate simultaneous effects of four main factors including solvent-tomaterial ratio, extraction time, ultrasonic power, and extraction temperature. The optimal conditions for fucoidan extraction were identified with solvent-to-material ratio of 24 : 1 mL/g, extraction time of 49 min, ultrasonic power of 360 W, and extraction temperature of 54 � C. The highest yield of TPS obtained under these conditions was 7.1203 mg/g. Besides, extraction of fucoidan using hot water method was also carried out to compare with UAE method in terms of TPS content. The bioactivity tests showed the extract had the anti-oxidation activity with the half-maximal inhibitory concentration (IC 50 ) value of 0.4261 � 0.0008 mg/mL, cytotoxic effect on breast carcinoma cells and human lung carcinoma with IC 50 values of 95.80 � 4.75 and 129.00 � 0.66 μg/mL, respectively.
