Abstract
Gardenia resinifera is used in several traditional medicines. The present study was aimed to the synthesis and characterization of MnO2 nanoparticles from G. resinifera leaf extract. Synthesis of MnO2 nanoparticles was achieved by mixing manganese acetate with hot aqueous extract of G. resinifera dry leaves. The synthesized MnO2 nanoparticles were characterized using UV–Visible spectroscopy, PSA, FT-IR, XRD, SEM-EDAX, and HR-TEM analysis. The results of the above-mentioned studies indicated that the synthesized MnO2 nanoparticles are 17–35 nm and spherical in shape. The results of FT-IR study shows the presence of different functional groups that may exhibit various biological activities. The synthesized MnO2 nanoparticles harbor significant antimicrobial activity.
