The medicinal property of Parmotremagrayanum tends to add value in drug industry. The most sensible organism of P.grayanumhas its own regal and exclusive biological property among other plant kingdoms. Antioxidant activity of P.grayanumhas been evaluated using four different choice of solvents such aspetroleum ether, ethanol, ethyl acetate and water. To attain and strengthen the respective results, the following assay has been carried out. DPPH, FRAP and H2O2 assay are achieved in order to ascertain the consistency of all the results. The present assessment was instigated from antibacterial activity of lichen extract against Salmonella enterica, Bacillus anthrax, Escherichia coli, Enterobacteraerogenes, Streptococcusaureus. The hypothesis on the four extracts were build up on the basis of deserving maximum biological activity at various concentration. It was revealed by the investigated ethanolic extract which has maximum ability to inhibit the growth of pathogenic bacteria and the production of free radicals at the concentration of 100?g/ml. It lucidly shows the extracts are concentration dependent. Lichens are the tenets of ethnic group who are still used as “medicinal tea” in Nepal, India. The fact behind is the contemporary action of lichen substances which are consist of active compounds. They were summarized here which may cause the potential efficacy of lichen in biomedical application.
