A Study on The Applications of Silver Nanoparticle Synthesized Using The Aqueous Extract And The Purified Secondary Metabolites of Lichen Parmelia perlata
Journal Title: International Journal of Pharmaceutical Science Invention - Year 2017, Vol 6, Issue 10
Abstract
Lichens are generally a symbiotic association between a fungal and an algal partner. They produce an array of secondary metabolites that are common in plants or higher fungi but 80% of metabolites are produced specifically by lichens. The secondary compounds produced by lichens are commonly referred to as “Lichen acids’’ and are produced primarily by the mycobiont partner and are deposited externally on hyphae. The lichen acids possess pharmaceutical applications such as antimicrobial, antiviral and anticancer properties. The Present study was carried out on the synthesis, characterization and application of silver nanoparticles using the aqueous extract and the individual purified compounds of Lichen Parmelia perlata. The Silver nanoparticles were synthesized using the aqueous extract and using the purified compounds obtained from the methanolic extract and the nanoparticles thus obtained were characterized by means of UV-Visible spectroscopy, Fourier transform infrared spectroscopy and Scanning electron microscopy. The applications of these nanoparticles were determined by studying their antimicrobial, antioxidant and antidiabetic activity. Many reports are available for the synthesis of nanoparticle using the aqueous extracts but the nanoparticle synthesis using the individual secondary compounds were not carried out before so this study was one such attempt to identify the stabilizing and reducing potential of the secondary compounds in the synthesis of silver nanoparticle that could prove to be useful to the mankind for different applications.
