| Abstract:
|
Leucas aspera (Lamiaceae)is a highly medicinal aromatic herb used in ancient medicine. This plant is used in
Indian traditional medicines Ayurveda, Siddha and has various pharmacological activities. The scope of this
study is to synthesize silver nanoparticles (SNPs) using aerial region of L. aspera, characterization of SNPs, to
screen antimicrobial activities and photocatalytic degradation of textile dyes. The synthesized SNPs were
characterized by ultraviolet (UV) visible spectrum, Fourier transform infrared (FT-IR), X-ray diffraction (XRD),
Scanning electron microscopic (SEM) and Energy-dispersive X-ray spectroscopy (EDX). L. aspera SNP (Leucas
aspera silver nanoparticle) sample was examined photocatalytic capacity by three different organic dyes.
Antibacterial activity of L. aspera SNP sample was analyzed on five bacterial organisms by well diffusion
method. The L. asperaplant SNPs have absorbance peak at 265 nm for reaction at room temperature. The FTIR results also showed interaction between the plant extract and Ag-NPs due to the similarity in peak patterns.
The XRD pattern of the present study clearly exhibits that the synthesized SNPs were crystalline in nature.
The obtained SEM image shows the morphology of SNPs were mainly spherical, ellipsoidal and some irregular
shape. The EDX results indicates that Ag-NPs display an absorption peak at 3keV, shows the presence of silver
element.
