The characterization, renoprotection and antioxidation of enzymatic and acidic exopolysaccharides from Hypsizigus marmoreus.

The present work was designed to investigate the characterization, as well as the antioxidation and renoprotection in streptozocin (STZ)-induced diabetic mice, of exopolysaccharides (EPS) and the enzymatic-EPS (EEPS) and acidic-EPS (AEPS) hydrolysates, which were separated from the fermentation liquor of Hypsizigus marmoreus. Animal results demonstrated that EPS, EEPS and AEPS had potential antioxidant and renoprotective effects, especially EEPS. Additionally, they were the most effective, reflecting increases in superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), total antioxidant capacity (T-AOC), and albumin (ALB) of 168.

Purification, in vitro antioxidant and in vivo anti-aging activities of soluble polysaccharides by enzyme-assisted extraction from Agaricus bisporus.

In present study, the soluble polysaccharides by enzyme-assisted extraction from Agaricus bisporus (EnAPS) and its purified fractions of EnAPS-1, -2 and -3 were successfully obtained, and the antioxidant activities and anti-aging effects were investigated. The in vitro antioxidant assay demonstrated that EnAPS-2 had superior scavenging activities on DPPH and hydroxyl radicals, chelating activities of Fe and reducing power. The in vivo animal experiments showed that both EnAPS and its purifies fractions had potential anti-aging effects against the d-galctose-induced aging diseases on liver, kidney, brain and skin, possibly by increasing the antioxidant enzymes, reducing the lipid peroxidation, improving the organ functions and remitting the lipid metabolism.

Characterization, antioxidation, anti-inflammation and renoprotection effects of selenized mycelia polysaccharides from Oudemansiella radicata.

The present work investigated the characteristics, antioxidative, anti-inflammative and renoprotective effects of mycelia selenized polysaccharides (MSPS) from Oudemansiella radicata on lipopolysaccharide (LPS)-induced kidney damaged mice. The results demonstrated that both MSPS and mycelia polysaccharides (MPS) showed potential renoprotective effects reflecting by decreasing the serum levels of CRE, BUN and UA, increasing the nephritic enzyme activities of SOD, GSH-Px, CAT and T-AOC, reducing the activities of MPO, as well as down-regulating the contents of MDA and LPO, respectively. And the MSPS showed superior effects.

Production and in vivo antioxidant activity of Zn, Ge, Se-enriched mycelia by Cordyceps sinensis SU-01.

Cordyceps sinensis, a traditionally edible and medicinal fungus in China, cannot be artificially solid-cultured. Zinc (Zn), germanium (Ge), and selenium (Se) are the essential trace elements for human body. In this work, C.
