ABSTRACT: Parmelia perlata (Huds) Ach. (Lichen, parmeliaceae), Commonly known as black stone flower(pathar ke pool) in India, and is usually used as a spice to enhance the taste and flavor of the foods. It is also useful to treat sores, boils, inflammations Seminal weakness and amenorrhea. OBJECTIVE: This study was to make photochemical screening to determine the secondary metabolite present on Parmelia perlata and to test efficacy of P.perlata, which is used in traditional medicine for infection and wound healing against test bacteria and fungi.a METHOD: Preparation of plant extract by percolation process, that is macerated plant powders were soaked in solvents such as Ethanol, Acetone, Aqueous Double distilled water individually. The phytochemical screening is done on the dried powder different solvents extract to investigate the phytochemical groups as alkaloids, flavonoids, terpenoids, tannins, phenolic compounds, quinines, cardiac glycosides, Saponines and steroids etc. and also identified primary metabolites like amino acids, proteins and polysaccharides. and also in this present study aims to green synthesis of silver nano-particles using parmelia perlate (Lichen) thalli extracts. And then characterization of the synthesized silver nano-particle with plant extract by UV-visible, FT-IR, XRD, SEM. The bio-reduction of aqueous silver ions by the plant extract of thalli parmelia perlata is a good source for green chemistry approach. CONCLUSION: This green method is simple, rapid, Eco-friendly, and reliable and itmay have a potential use in the bio-medical applications. In the future, selection of such plants may create a new plat-form for realizing the potential of herbal medicines In Nano-science for drug delivery.
