RÉSUMÉ

The forest region of the Ranchi District of Jharkhand, India, is rich with various wild mushrooms. Of the 200 samples collected, 9 species were identified and subjected to medicinal studies. For antibacterial assay, 4 strains of bacteria (namely, Escherichia coli, Salmonella typhi, Pseudomonas fluorescens, and P. putida) were used. For antifungal assay, 4 strains of fungi (namely, Aspergillus niger, A. flavus, Microsporum canis, and Cladosporium herbarum) were used. Also, tests such as the α-amylase inhibition assay, a measure of antidiabetes activity, and antioxidant assays such as the DPPH, ferric-reducing antioxidant power, and acetylcholinesterase-inhibitory assays, which determine anti-Alzheimer disease properties, were carried out. Agaricus bisporus, A. campestris, Russula cyanoxantha, and Amanita pantherina all showed a maximal zone of inhibition against P. putida and M. canis. Ganoderma lucidum, Astraeus hygrometricus, and R. emetica all showed a maximal zone of inhibition against E. coli and A. flavus. Pleurotus populinus showed a maximal zone of inhibition against P. fluorescens and C. herbarum. P. pulmonarius showed a maximal zone of inhibition against S. typhi and M. canis. Also, all the collected samples showed α-amylase-inhibitory activity. A. hygrometricus showed maximal DPPH activity and ferric-reducing antioxidant power, whereas A. bisporus showed maximal acetylcholinesterase inhibitory activity.
