“…The mechanism of the potential protective role of tetrodotoxin in ameliorating the toxic effects of EAC cells is presumably because of its antioxidant and free-radical scavenging properties. Similar results have been obtained from treatment of hepatotoxicity with other natural marine animals such as marine brown alga (Makhmoor et al, 2013), Sepia kobiensis cuttlebone (Ramasamy et al, 2014) and Sea Cucumber Holothuria atra extract (Dakrory et al, 2015). These findings contrast with those of Yamaguchi (1996), who found that liver and kidney sections showed congestion in mice after intraperitoneal injection of tetrodotoxin prepared from the ovary of Takifugu porphyreus.…”

“…All the four samples showed typical absorption peaks of polysaccharides: the absorption bands at 3200–3400 cm −1 , representing O–H vibrations; cm −1 , others, in order : 2927–2891 cm −1 (C–H), 1638–1597 cm −1 (C=O), 1410–1415 cm −1 (C=O), 1247–1257 cm −1 (S=O), and 1134–1150 cm −1 (C–O) characteristic peaks vibrations, [8,15]; 891 and 882 cm −1 represent the presence of β-pyranoses [16]. …”

“…Therefore, the reducing capacity of a compound may serve as a significant indicator of its potential antioxidant activity [15]. As shown in Figure 7, the reducing power of the seaweed polysaccharides (DAP, ULLP, SCP, and GLP), determined at 700 nm showed a dose-dependent response.…”

Four seaweed polysaccharides were extracted from Sarcodia ceylonensis, Ulva lactuca L., Gracilaria lemaneiformis, and Durvillaea antarctica, respectively, by microwave-assisted extraction. The effect of three significant variables (extraction time, extraction temperature, and the ratio of water to raw material) on the process for extracting polysaccharides was investigated, along with the optimization of the extraction using the response surface method (RSM) with a Box–Behnken design. The polysaccharide structure, monosaccharide composition, degree of sulfation, and molecular weight (MW) distribution were analyzed by infrared (IR) spectrometry, gas chromatography (GC), and high-performance gel permeation chromatography (HPGPC). IR spectrometry showed that Sarcodia ceylonensis polysaccharide (SCP), Ulva lactuca L. polysaccharide (ULLP), and Durvillaea antarctica polysaccharide (DAP) were all sulfated polysaccharides and, except Gracilaria lemaneiformis polysaccharide (GLP), all belong to β-pyranosidic polysaccharides. The average molecular weight (MW) of SCP, ULLP, GLP, and DAP was 466, 404, 591, and 482 kDa, respectively. The quantitative and comparative results with external standards indicated that the main monosaccharide in SCP and ULLP was mannose; and GLP and DAP were mainly composed of galactose and glucose, respectively. Then the in vitro antioxidant activity of all of the polysaccharides was evaluated using different assays—2,2–azino –bis (3-ethylbenzthiazoline-6- sulfonate) (ABTS), hydroxyl radical, nitrite scavenging capacity, and reducing power—and the relationship between their antioxidant activity and chemical characteristics were also examined. ULLP presented the highest ABTS radical scavenging activity; ULLP, SCP and DAP also showed a strong effect on the ABTS radical scavenging activity. SCP and ULLP exhibited excellent hydroxyl radical scavenging activities, about 83.33% ± 2.31% and 80.07% ± 2.17%, respectively, at 4 mg/mL. The reducing power of DAP was relatively more pronounced than that of the three other polysaccharides. However, the nitrite scavenging activities of the four seaweed polysaccharides were weaker than other antioxidant activity (ABTS), hydroxyl radical scavenging capacity, and reducing power. In addition, GLP exhibited lower activities than the other three samples in all of the tests for the antioxidant activity.
