“…These results are in accordance with the literature data for commercial mushrooms (Yang et al, 2002). Also, the high content of microelements in fungal samples could contribute to the pro-oxidative effect (Karaman et al, 2009).All the examined MeOH extracts exhibited scavenging effects on OH that increased in a dose-dependent manner. Inhibition of OH generation at 400.0 μg/mL was graded as follows:…”

The antioxidant activity of organic extracts of eight fungal species, Ganoderma lucidum, Ganoderma applanatum, Meripilus giganteus, Laetiporus sulphureus, Flammulina velutipes, Coriolus versicolor, Pleurotus ostreatus and Panus tigrinus, was evaluated for free radical (DPPH· and OH·) scavenging capacity and an effect on lipid peroxidation, and the antibacterial activity was tested by the agar well diffusion method. The highest DPPH· scavenging activity was found in the methanol extract of G. applanatum (12.5 μg/mL, 82.80%) and the chloroform extract of G. lucidum (510.2 μg/mL, 69.12%). The same extracts also showed the highest LP inhibition (91.83%, 85.09%) at 500 μg/mL, while the methanol extracts of G. applanatum and L. sulphureus showed the highest scavenging effect on OH· radicals (68.47%, 57.06%, respectively) at 400 μg/mL. A strong antibacterial activity against Gram-positive bacteria was also manifested. The antioxidative potencies correlated generally with the total phenol content (0.19-9.98 mg/g). The HPLC determination showed that the majority of analysed species contained gallic and protocatechic acids. Consequently, these fungi are shown to be potential sources of antioxidative and antibacterial agents.

“…Zeng et al (2012) demonstrated that F. velutipes possesses the highest phenolic content based on it having the highest antioxidant activities in terms of ferric reducing antioxidant power and ferrous ion chelating activity among three other Australian mushrooms. In contrast, Karaman et al (2009) found that F. velutipes has poorer phenolic content compared to other lignicolous fungi, suggesting that the prominent antioxidant activity may due to other secondary biomolecules which had yet to be identified at the time of the study. Besides the fruiting body of F. velutipes , the spent culture medium of the mushroom was also shown to contain high amount of phenolic acids and show potent antioxidative action against lipid oxidation, demonstrating its role as a potential antioxidative agent (Bao et al, 2010a).…”

Flammulina velutipes (enoki, velvet shank, golden needle mushroom or winter mushroom), one of the main edible mushrooms on the market, has long been recognized for its nutritional value and delicious taste. In recent decades, research has expanded beyond detailing its nutritional composition and delved into the biological activities and potential health benefits of its constituents. Many bioactive constituents from a range of families have been isolated from different parts of the mushroom, including carbohydrates, protein, lipids, glycoproteins, phenols, and sesquiterpenes. These compounds have been demonstrated to exhibit various biological activities, such as antitumour and anticancer activities, anti-atherosclerotic and thrombosis inhibition activity, antihypertensive and cholesterol lowering effects, anti-aging and antioxidant properties, ability to aid with restoring memory and overcoming learning deficits, anti-inflammatory, immunomodulatory, anti-bacterial, ribosome inactivation and melanosis inhibition. This review aims to consolidate the information concerning the phytochemistry and biological activities of various compounds isolated from F. velutipes to demonstrate that this mushroom is not only a great source of nutrients but also possesses tremendous potential in pharmaceutical drug development.

“…4). Some species of mushrooms are excellent antioxidants, because the EC 50 values are lower than for tert-butylated hydroxytoluene (KARAMAN et al, 2009). The strongest scavenging ability and a drop of EC 50 value obtained for the highest concentration of Se (Tables 1-3) (TSAI et al, 2007;KIM et al, 2008;HELANO et al, 2012) also documented positive correlations between phenolics and DPPH radical scavenging activity.…”

The phenolic and fl avonoid contents and composition and the antioxidant ability in Hericium erinaceus, Ganoderma lucidum, and Agrocybe aegerita under selenium (Se) addition to growth medium were studied. The contents of total Se in fruiting bodies of controls (0 mM of Se) were 4.58 (A. aegerita), 8.53 (G. lucidum), and 14.29 (H. erinaceus) mg kg -1 dry weight (DW), and was signifi cantly increased by Se enrichment of substrate. The total phenolics in fruiting bodies of controls of H. erinaceus, G. lucidum, and A. aegerita were signifi cantly lower (17.10, 28.11, and 16.05 mg of gallic acid equivalent (GAE)/g of extract, respectively) than for Se-rich mushrooms (26.29, 40.29, and 20.07 mg GAE/g of extract, respectively). Total fl avonoid content for H. erinaceus, G. lucidum, and A. aegerita increased after Se supplementation from 368.6 to 445.6, 469.9 to 627.7, and 318.1 to 393.9 μg g -1 of extract, respectively. The results show that the mushrooms have superior antioxidant properties after Se addition, because the scavenging ability on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals was improved.
