“…Similar to the above results, many studies have demonstrated that selenium-polysaccharide exhibits the antioxidant activity in vitro [44][45][46][47]. The possible chemical mechanisms for the antioxidant activity were shown as follows: firstly, the hydroxyl groups in Se-ESPS-B1 and ESPS-B1 were reacted with ferric iron, which reduced the production of free radicals induced by ferric iron [48]. Secondly, selenium in Se-ESPS-B1 could also directly trap the electrophilic free radicals [49].…”

In order to obtain and explore selenide composed of selenium and polysaccharide, three parameters were selected to optimize the synthesis process of selenium-Euryale ferox Salisb. polysaccharide (Se-ESPS) by Box-Behnken design. Furthermore, ESPS-B1 separated from ESPS was selenitized to Se-ESPS-B1 by the optimal synthesis process, then the characterization, and antioxidant activity in vitro of Se-ESPS-B1 were explored. The result manifested that the Se content of Se-ESPS was (2.915 ± 0.03) mg/g according to the optimal synthesis process of Se-ESPS (reaction time at 5 h, reaction temperature at 81 ℃, weight ratio of Na2SeO3 to ESPS at 0.9 g/g). A series of detection results indicated that the characterizations of Se-ESPS-B1 were apparently distinguished from that of ESPS-B1. Moreover, the antioxidant experiments in vitro demonstrated that Se-ESPS-B1 could exert antioxidant activity by scavenging DPPH, ABTS,·OH, and increasing reduction ability. In conclusion, the synthesis process is an effective approach to harvest selenium-polysaccharide, and Se-ESPS-B1 may be utilized as a potential antioxidant or selenium nutritional supplement.

“…Selenium is a trace element essential to many bacteria and animal species. [1,2,3,4] This essentiality is improved by biochemical connection between selenium and vitamin E. [5,6] There are multiple chemical forms of bioactive selenium, among which selenocysteine, the 21 st amino acid, has a prominent role. [7] Glutathione peroxidases (Gpx) are selenoenzymes responsible for scavenging peroxides and hydrogen peroxide at the expense of glutathione (GSH), preventing oxidative damage.…”

View full text Add to dashboard Cite

This review article deals with organic synthesis from the perspective of selenium-77 nuclear magnetic resonance (NMR) spectroscopy. Different types of organic reactions are briefly discussed, incorporating mechanism aspects through 77 Se NMR observable intermediates and byproducts. The 77 Se NMR experiments are demonstrated in terms of structural characterization and new insights for organic reactions. The ability to visualize different molecules in a reaction mixture provides a facile and versatile route for the development of synthetic organoselenium compounds. Thus, the review describes the strategies accomplished mainly in the past five years in the syntheses and applications of the organoselenium compounds, focusing on 77 Se NMR spectroscopy.

“…HSI and VSI of sh were in uenced by 0.7mg/kg Nano-Se and 1% Nano-Se-enriched G. lemaneiformis, but not by 1% G. lemaneiformi. These indicate that dietary Nano-Se and Nano-Se-enriched G. lemaneiformis was better than dietary G. lemaneiformis in promoting immune function, since it is generally acknowledged that the immunity of the organism is related to the development of immune organs [13] . On the other hand, elevation of HSI re ected an increase in energy storage in grouper fed the dietary with Nano-Se or Nano-Se-enriched G. lemaneiformis [24], which is consistent with the result of weight gain in the same groups.…”

“…G. lemaneiformis is known with excellent Se enrichment ability [11]. Se can promote the activity of functional substances such as polysaccharides in G. lemaneiformis by modifying its structure [12,13]. It is feasible and effective to use proper G. lemaneiformis as feed ingredient for juvenile Paci c white shrimp [14].…”

Background: Nano-Se-enriched Gracilaria lemaneiformis (G. lemaneiformis) as feed ingredient on aquatic animals remained largely unknown. Feeding experiment was conducted for a total of 45 days to research the biological impacts of nano-selenium (Nano-Se) (group N), G. lemaneiformis (group G) and Nano-Se-enriched G. lemaneiformis (group NG) on growth, selenium concentration, oxidation, immunity and nutrition of Epinephelus coioides.Results: At each tested time point, the weight gain rate, specific growth rate and feed conversion rate of group N, group G and group NG were significantly increased in contrast to those of the control group (group C). A remarkable increase of the hepatosomatic index (HSI) and viscerosomatic index (VSI) was observed in group N and group NG. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) of fish in group N, group G and group NG were significantly enhanced relative to those in group C. The immune system was also activated by showing an elevated expression level of various immunological genes including Immunoglobulin M, tumor necrosis factor-α and Interleukin -8. The muscle Se content in group N and group NG was 31- and 40.5-fold that of the control group (group C), respectively. The liver Se value of group N and group NG was 1.06 and 2.50 times higher than that of group C, respectively. The lipid and moisture values of group N and group NG are increased and reduced, respectively, in comparison to that of group C. The diet supplementation of Nano-Se-enriched G. lemaneiformis led to significant increase of the protein content, delicious amino acids along with total amino acids content in grouper. Conclusions: Our results demonstrate a great application potential of Nano-Se-enriched G. lemaneiformis as dietary additive in grouper.

Research progress on the biological activities of selenium polysaccharides

Abstract: Selenium polysaccharides, an important organic selenium product, possess better antioxidant, antitumour, immune regulation, hypoglycaemic, and heavy metal removal activities than that of either polysaccharides or inorganic selenium.
