Abstract
The main aim of this study was to evaluate the comparative antibacterial potential of silver and Iron nanoparticles synthesized from aqueous plant extracts of Aloe vera. The synthesized nanoparticles were characterzed by UV-VIS spectroscopy, Fourier Transform Infra-Red spectroscopy and Transmission Electron Microscopy. The antibacterial activity of synthesized silver and iron nanoparticles was compared by agar well diffussion method and minimum inhibitory concentration was also calculated. The zone of inhibition varied in range of 9 to 18 mm for silver nanoparticales and 10 to17 mm for iron nanoparticles. The maximum zone of inhibition for silver nanoparticles was 18 mm against Proteus mirabilis. The maximum zone of inhibition for iron nanoparticles was 17 mm against Klebsiella pneumonia. MICs of silver nanoparticles were found to be in a range from 195 to 780 μg/ml and that of iron was 390 to 1560 μg/ml against tested microbes. The synthesized silver nanoparticles of aqueous Aloe vera extracts have shown good antibacterial efficacy as compared to iron nanoparticles and may prove to be better antibacterial agent against wide range of microbes.
Highlights
Plants are rich sources of various medicinally important substances and they explore the huge diversity in therapeutic and clinical aspects of the society from ancient times
Reporting more than 2000 species of medicinally important plants with high potential abilities for use in different traditional medicine systems, India has a rich culture of medicinal herbs and spices but chemically and pharmacologically studies for their medicinal potential are very few in literature [4,5]
Reaction was visible as a colour change from light green to brown within 24 h of the addition of reaction mixture
Summary
Plants are rich sources of various medicinally important substances and they explore the huge diversity in therapeutic and clinical aspects of the society from ancient times. Due to having wide biological and medicinal properties, high safety margins and lesser costs, there is a great demand of herbal medicines in both developed and developing countries as a source of primary health care [2,3]. Aloe vera has been traditionally used for a variety of medicinal purposes and significantly involved in indigenous medicine system of India. It has gained high importance for its diverse therapeutic properties. Aloe vera gel has been used for the treatment of several skin cuts and burn abnormalities too [14]
