Phytochemical Screening, Total Phenolic Content, Antibacterial and Antioxidant Activity of Wild Edible Mushroom Pleurotus Ostreatus

Abstract

The methanolic and aqueous extracts of dried wild edible mushroom were analyzed for phytochemical screening, antibacterial, antioxidant activity (DPPH) and total phenolic content. The preliminary phytochemical results showed the occurrence of active compounds such as carbohydrate, glycosides, phytosterols, phenol, tannins, flavanoids, alkaloid, terpenoids and saponins. The wild edible mushroom extracts showed varying degree ofinhibition on the test organisms (Escherichia coli, Staphylococcus aureus, Bacillus cereus and Salmonella typhi). P. ostreatus showed good antibacterial activities against all the microorganisms tested. P. ostreatus revealed a high phenolics concentration in methanolic extract (24.012 mg GAE/g) as compared to aqueous extracts (16.5468 mg GAE/g) and powerful antioxidant properties. The antioxidant activity of evaluated mushroom extracts gave positive results with free radical scavenging activity. The result obtained from this study has shown the potential of mushroom extract as a potent therapeutic agent and a food supplement. It could find applications in the prevention of free radical-related diseases as a source of bioactive compounds.

Evaluation of Trachyspermum Ammi Seeds for Antimicrobial Activity and Phytochemical Analysis

“…The phytochemical tests were carried out for four different extracts as mentioned above using the standard methods [27][28][29][30].…”

Phytochemical, Antioxidant and Antitumor activity of edible mushroom Pleurotus ostreatus

“…With the onset of new antitumor drugs and their adverse side effects, new non-invasive approaches for cancer treatment are being developed. Fungi have an innate ability to synthesize numerous phytochemicals that have potential anti-inflammatory (Schneider et al, 2011) (20) , antibacterial (Parihar et.al., 2015) (15) , antitumor (Wang et al, 2000) (26) and other medicinal properties. This study suggests that ethyl acetate extract of Pleurotus ostreatus has the potential antitumor activity against skin cancer cells.…”

“…In this regard various worked and studied this fungus on many characteristic features viz., characterization of fruit body morphology on various environmental conditions in Pleurotus ostreatus (Jang, et al, 2003) (11) . The studies on phytochemical screening, antioxidant and antibacterial activity were broadly defined by Parihar et al (2015) (15) . The Pleurotus ostreatus species were regarded as therapeutic food for their antioxidant, antimicrobial, antitumor and antiviral properties.…”

Phytochemical constituents and antimicrobial evaluation of ethanolic extracts from Pleurotus spp. cultivated on substrate fortified with selenium

“…Phytochemicals screenings were carried out on the powdered samples to identify their major constituents such as alkaloids, saponins, tannins, flavonoid, steroid, phytate, phenols and oxalate using standard qualitative methods as described by Parihar et al (2015).…”
