“…Similar antioxidant properties have also been reported for other edible mushrooms, including Agrocybe cylindracea and H. marmoreus, both of which belong to the Tricholomataceae family (Tsai et al, 2006). Potent antioxidant activity was also found in crude methanolic and aqueous extracts of the common Chinese edible mushrooms L. edodes (shiitake mushroom), Pleurotus tuber-regium and V. volvacea (straw mushroom) and a lesser known edible mushroom, A. aegerita, belonging to the family Bolbitiaceae, was evaluated by the β-carotene bleaching method, DPPH radical scavenging activity and erythrocyte hemolysis assay (Lee et al, 2007).…”

Abstract:Mushrooms have been known for their nutritional and culinary values and used as medicines and tonics by humans for ages. In modern terms, they can be considered as functional foods which can provide health benefits beyond the traditional nutrients. There are monographs that cover the medicinal and healing properties of some individual traditional mushrooms. There has been a recent upsurge of interest in mushrooms not only as a health food which is rich in protein but also as a source of biologically active compounds of medicinal value which include complementary medicine/dietary supplements for anticancer, antiviral, hepatoprotective, immunopotentiating and hypocholesterolemic agents. However the mechanisms of the various health benefits of mushrooms to humans still require intensive investigation, especially given the emergence of new evidence of their health benefits. In the present paper the medicinal potential of mushrooms is being discussed.

“…It is known that mushrooms have anti-oxidant activity (Mau et al, 2002). Tsai et al (2006) measured the anti-oxidant activity of hot water extracts from Agrocybe cylindacea, and we found ORAC values that indicolumn (i.d. 4.6 × 250 mm) with gradient elution (condition 1) at 0.8 mL/min.…”

We measured the anti-oxidative and anti-inflammatory activities of hot water extracts prepared from 11 species of mushrooms. Anti-oxidative activity was evaluated using the oxygen radical absorbance capacity method, and anti-inflammatory activity was examined by measuring the inhibition of lysine chloramine formation by hypochlorous acid. Hot water extracts of Grifola gargal (G. gargal) showed the strongest anti-oxidative activity and inhibitory effects on lysine chloramines. Hot water extracts of G. gargal were evaluated by HPLC and divided into 8 fractions. The most active fraction among these 8 fractions was further purified by preparative HPLC. The active component isolated by HPLC was identified as ergothioneine (EGT) using spectral analysis. On HPLC analysis, the EGT content in G. gargal was the highest among the 11 species of mushrooms. We also examined the protective role of EGT by examining the inflammatory response of adipocyte cells induced by tumor necrosis factor-α.

“…The reducing ability of LCS was assayed as described previously (Tsai et al, 2006). Varying concentrations of LCS (200 ml) were mixed with an equal volume of 0.2 M phosphate buffer (pH 6.6) and 1 % (w/v) potassium ferricyanide.…”

Accumulating evidence suggests that probiotic bacteria play a vital role in modulating various aspects integral to the health and well-being of humans. In the present study, probiotic attributes and the antioxidant, anti-inflammatory and neuromodulatory potential of Enterococcus faecium CFR 3003 were investigated by employing suitable model systems. E. faecium exhibited robust resistance to gastrointestinal stress conditions as it could withstand acid stress at pH 1.5, 2 and 3. The bacterium also survived at a bile salt concentration of 0.45 %, and better tolerance was observed towards pepsin and trypsin. E. faecium produced lactic acid as a major metabolic product, followed by butyric acid. Lyophilized cell-free supernatant (LCS) of E. faecium exhibited significant antioxidant capacity evaluated against 1,1-diphenyl-2-picryl-hydrazyl, ascorbate autooxidation, oxygen radical absorbance and reducing power. Interestingly, E. faecium, Lactobacillus rhamnosus GG MTCC 1408 and LCS showed a significant anti-inflammatory effect by negatively modulating TNF-a production and upregulating IL-10 levels in LPS-stimulated macrophage cell lines. In an in vivo mice model, the propensity of probiotic supplements to modulate endogenous oxidative markers and redox status in brain regions was assessed. Young mice provided with oral supplements (daily for 28 days) of E. faecium and L. rhamnosus exhibited diminished oxidative markers in the brain and enhanced activities of antioxidant enzymes with a concomitant increase in c-aminobutyric acid and dopamine levels. Collectively, our findings clearly suggest the propensity of these bacteria to protect against tissue damage mediated through free radicals and inflammatory cytokines. Although the underlying molecular mechanisms need further studies, it is tempting to speculate that probiotics confer a neuroprotective advantage in vivo against oxidative damage-mediated neurodegenerative conditions.
