Antioxidant Properties of Ethanolic Extracts from Culinary-Medicinal Button Mushroom Agaricus bisporus (J. Lange) Imbach (Agaricomycetideae) Harvested at Different Stages of Maturity

Changes in reactive oxygen species production and antioxidant enzyme activity of Agaricus bisporus harvested at different stages of maturity

“…Tsai et al . found that ethanolic extracts of A. bisporus harvested at different stages of maturity showed comparable reducing power, 1,1‐diphenyl‐2‐picrylhydrazyl radical‐scavenging ability and ferrous ion‐chelating ability . The antioxidant activity was closely related to the contents of ascorbic acid, total tocopherols and phenols.…”

Composition and Biological Properties of Agaricus bisporus Fruiting Bodies- a Review

“…Oxidative stress and free radical production can be caused by diseases, long periods of stress or natural aging. There are internal natural mechanisms in the human organism that can prevent oxidative stress, such as the production of free radical species -superoxide dismutase (SOD) or catalase [Elmastas et al, 2007;Hu et al, 2015;Maseko et al, 2014;Tsai et al, 2008]. These natural mechanisms should be aided by providing antioxidants with food.…”

“…These natural mechanisms should be aided by providing antioxidants with food. As a source of antioxidants, A. bisporus has for many years been examined for the potential preventive action in hypertension, hypercholesterolemia or cancer [Elmastas et al, 2007;Tsai et al, 2008]. Due to their acetylcholinesterase and butyrylcholinesterase inhibiting activity, A. bisporus extracts can be potentially applied in Alzheimer's disease treatment [Öztürk et al, 2011].…”

“…Methanol extracts from this species have been examined for antioxidant activity derived from high concentrations of α-tocopherol and these have also revealed the presence of β-carotene [Tsai et al, 2008]. The antioxidant effect of A. bisporus is strongly correlated with substances found in this mushroom that act as reducers in many chemical reactions, and that are able to scavenge free radicals or chelate metal ions [Elmastas et al, 2007;Glamočlija et al, 2015;Vamanu & Nita, 2014].…”

Antioxidant Properties of Edible Basidiomycete Phellinus igniarius in Submerged Cultures

“…Mushrooms are very important resources of antioxidants and antitumor activity researches. Many therapeutic evidences have been reported for medicinal mushrooms such as antitumor (Monro 2003; Lee and others 2006; Mathew and others 2008), anticancer and immune‐stimulatory effects (Wasser and Weiss 1999), immunomdulatory effect (Kuo and others 2006), stimulating macrophage activity and anti‐hepatitis B virus activity (Lee and others 2002), and free‐radical scavenging (Mau and others 2002a, 2002b; Tsai and others 2008). Antioxidant activity is one important bioactivity assayed from mushrooms.…”
