Green Synthesis of Silver Nanoparticles Using Amaranthus Viridis Plant Extract and Their Catalytic Activity on Degradation of Azo Dyes Methyl Orange and Congo Red
: In the present work, we have prepared AgNPs using the leaf extract of Amaranthus viridis L (Family Amaranthaceae). It is commonly known as “Chowlai” is a
common wild vegetable and weed of cultivation. Amaranthus viridis contains several compounds like amino acids lysine, arginine, histidine, cystine, phenylalanine, leucine, isoleucine, valine, threonine, methionine, tyrosine etc. In search of new activities chemical entities, pytochemical screening of the extract from leaves of Amaranthus viridis L. indicates the presence of biologically active constituent: saponins, tannins and phenols, flavonoids, alkaloids, cardiac glycoside, steroid and triterpenoids. Amaranthus viridis L have some chemical constituent that exhibits potent anti- inflammatory, antihepatotoxic, antiulcer antiallergic, antiviral actions. Amaranthus viridis L used in Indian and Nepalese traditional system to reduce labour pain and act an antipyretic The synthesized silver nanoparticle showed excellent antibacterial and antifungal activity and shows good catalytic activity for the degradation of a toxic azo dyes, congo
red and methyl orange.
