Biological synthesis of Nanoparticles from Medicinal Plants: Recent Studies

Abstract

In a recent trend, nanotechnology has been developed to be an important field of research in various fields like medicinal chemistry, pharmaceuticals and all. On the other hand, compared to chemical method of synthesis, method of synthesis of nanoparticles by green method is simple, effective & ecofriendly. Plant extracts are obtained from the plant, creep, cereals, etc. generally natural extracts are prepared by decoction method or solid powder formation method. The natural extracts are very much effective in the medicinal approach. The study of Nano sized particles towards natural extracts has given a novel way in the field of medicines. So from the nanomaterials of natural extracts, one can expect still good effective results. As we know that preparation of nanoparticles through green approach is one of the good selections in the view of betterment of ecology. Therefore by taking aqueous extracts of medicinal plants’ parts and metal ions, nanoparticles can be synthesized. The plant extract and metal ions are taken in a fixed ratio and keep at room temperature for the reduction. The Changes in the Color confirmed the formation of nanoparticles. Further, the synthesized nanoparticles were characterized by UV, EPMA, XRD and FTIR data.
