Antioxidant Properties of Cap and Stipe from Coprinus comatus

Abstract

Coprinus comatus, also called chicken drumstick mushroom, is currently commercially available in China. Hot water and ethanolic extracts were prepared from cap and stipe of C. comatus fruit bodies and their antioxidant properties were studied. Ethanolic extract from stipe showed high antioxidant activity (80.6%) at 1 mg/mL. Reducing power of hot water extracts from cap was 1.653 at 10 mg/mL. Extracts from cap showed better scavenging ability on DPPH (57.9% at 1 mg/mL) than stipe ones. Ethanolic extracts were more effective in scavenging ability on hydroxyl radicals (57.4–61.3% at 5 mg/mL) than hot water extracts. Ethanolic extracts showed moderate scavenging ability on superoxide radicals (46.3–47.0% at 20 mg/mL). Naturally occurring antioxidant components including total phenols (3.60–20.00 mg/g), tocopherols (0.58–11.93 mg/g), flavonoids (0.19–3.52 mg/g) and polysaccharides (58.52–547.86 mg/g) were found in the extracts. Overall, extracts from cap were more effective for the antioxidant properties assayed.

Antioxidant/Anti-Inflammatory Activities and Chemical Composition of Extracts from the Mushroom Trametes Versicolor

“…Also, ethanol extracts from mushroom species Phellinus Quél and their isolated fractions exhibited antioxidant activity and protected PC 2 cells against oxidative damage [23]. Another study reported that ethanolic extracts from the mushroom Coprinus comatus possessed higher antioxidant activity (47.0% at 20 µg/mL) than hot water extract [24]. A peptide obtained from another fermented mushroom (Ganoderma lucidum) showed inhibitory activities toward lipid peroxidation and lipoxigenase activity, which has been used to examine anti-inflammatory activity [25].…”

A comparative overview of antioxidative properties and phenolic profiles of different fungal origins: fruiting bodies and submerged cultures of Coprinus comatus and Coprinellus truncorum

“…It is well known for its bioactive properties, such as antimicrobial (Zenkova et al 2003), antioxidant (Asatiani et al 2010), hypoglycemic (De Silva et al 2012), immunomodulator, antitumor (Zhao et al 2014) etc. In China, this fungus has been cultivated in a large amount, and its production was amounted to almost 382.000 tons in 2006 (Li et al 2010).…”

Nutrients and non-nutrients composition and bioactivity of wild and cultivated Coprinus comatus (O.F.Müll.) Pers.

“…Several bioactive functions have been attributed to this species along the time, both in cultivated and wild samples, such as hypoglycemic (Bailey et al, 1984), immunomodulatory and antitumor (Jiang et al, 2013) or antioxidant potential (Tsai et al, 2009;Li et al, 2010;Vaz et al, 2011). Mycelia extracts of C. comatus have been also studied revealing antioxidant potential (Tsai et al, 2009) and some extracts proved to interfere with androgen receptor function in LNCaP prostate cancer cells (Zaidman et al, 2008).…”

“…Pers., also known as shaggy ink cap, lawyer's wig or shaggy mane, is an edible mushroom species commonly found all over the world; moreover, it is also cultivated in many countries (Li et al, 2010). There are a few studies concerning chemical characterization of C. comatus in an attempt to qualify this species as a dietary option.…”
