Abstract

Justicia gendarussa (Burm) f. is one of the common, well known and important medicinal shrub. Justicia gendarussa (Burm) f. plant leaves medicinal properties such as, anti arthritic, anti-inflammatory and immunosuppressive activities and also this plant to cure many diseases. Ethanol and aqueous extract of the dry plant leaves were collected and qualitatively analyse the phytochemical compounds. Silver nano particles (AgNPs) were synthesised biologically from the aqueous extract of the Justicia gendarussa (Burm) f plant leaves. Then the AgNPs were characterised and confirmed by the analysis of UV, HR-TEM, and FE-SEM. In this study to explore the Antioxidant and anti-microbial activities using ethanolic extract and Silver nanoparticles of Justicia gendarussa (Burm) f plant leaves.The antioxidant assays are performed by ABTS, DPPH, NO and reducing power scavenging activity.The antimicrobial activity of the ethanolic extract and AGNPs were tested against 5 bacterial species.This study confirms the significant activities of antioxidant and antimicrobial against the ethanol extract and silvernano particles of J. gendarussa plant leaves.

Silver Nanoparticle Production Mediated by Vitis vinifera Cane Extract: Characterization and Antibacterial Activity Evaluation

“…Another study by Ahmed et al [ 34 ] also reported spherical AgNPs with a diameter of 34 nm when Azadirachta indica extract was used as the reducing and stabilizing agent. Irregular spherical shape and size between 20 and 100 nm was described in a study by Vijayakumar [ 35 ], where Justicia gendarussa extract was used for the phytofabrication of AgNPs.…”
