Abstract:

Medicinal plants have a higher safety margins in curing the diverse range of diseases caused by micro-organisms, due to their rich source in bioactive molecules. The biological route for synthesizing Ag-Nps by using those plants serves as a straight forward approach, to explore an alternative approach which has greater effect on killing drug resistant pathogenic microbes. In the present study an attempt has been made to determine the efficiency of antibacterial activity of Lawsonia inermis (Henna plant) aqueous extract has been encountered, due to their wide array of  phyto-chemicals present in them, the effect of L. inermis aqueous extract by challenging with 1mM AgNo3 and formation of Ag-NPs were subjected for characterization process viz., UV-Vis, SEM with EDAX, XRD, ZETA Potential analysis and  Particle size distribution. The results revealed that the presence of grain sized Ag-NPs was confirmed. Finally anti-bacterial activity was done by disc diffusion method against Gram- Positive & Gram – Negative bacterial strains which causes infectious diseases in humans. Their positive results showed that, they have great potential as anti-microbial compounds against pathogenic microbes studied and it can be used in the treatment of infectious diseases caused by bacteria.
