Mycochemical Screening and Study of Medicinal Properties of Two Amanita Species (Agaricomycetes) from Pakistan

Fresh basidiocarps of Amanita cinnamomescens and A. pakistanica were collected from Ayubia-Khanspur, Pakistan, during the 2018 monsoon season. Basidiocarps of A. cinnamomescens and A. pakistanica were evaluated for their mycochemicals, mineral composition, and antioxidant and antimicrobial activities. The percentage yield of extracts ranged from 4.13% to 18.20%. The extracts contained noticeable total phenolic contents (0.043 ± 0.02 to 0.046 ± 0.01 mg/g) and total flavonoid contents (0.090 ± 0.004 to 0.0935 ± 0.003 mg/g) and good radical scavenging ability according to the ABTS assay (79.74% ± 0.03% to 85.34% ± 0.02%) and the DPPH radical assay (35.77% ± 0.01% to 44.77% ± 0.003%). In addition, the tested extracts showed substantial antimicrobial activity, which ranged from 10 ± 0.33 to 32.66 ± 0.33 mm. Both mushrooms were also analyzed for their mineral content (sodium, potassium, calcium, nickel, cobalt, copper, zinc, manganese, chromium, and iron). It was concluded that A. cinnamomescens and A. pakistanica can be used as a potential source for formulation of dietary functional foods and pharmaceuticals with antioxidant and antimicrobial effects. To our knowledge, this is the first report on in vitro biological activities and mycochemical analysis of A. pakistanica and A. cinnamomescens from Pakistan.
