Abstract
Nanotechnology has marked a significant revolution in various areas of science and involved in the production and application of nanoparticles that can be used in different fields. Silver nanoparticles among other nanoparticles, have received substantial attention because of their unique properties. This study focuses on the green synthesis of silver nanoparticles using pomegranate peel extracts. Green synthesized silver nanoparticles have great advantages, including energy efficiency, low toxicity, high yields, cost-effectiveness, eco-friendliness, and ready availability. The Antioxidant potential of pomegranate peel aqueous extracts and synthesis of silver nanoparticles was carried out in Department of Biochemistry, Mahatma Phule Krishi Vidyapeeth, Rahuri. In the present study total five different solvents in order to polarity were used namely water, ethanol 60%, methanol 60%, ethyl acetate and petroleum ether respectively. In the extraction process solvent selection was a very important step because the solubility of required compounds was depend upon the polarity of the solvent. Method of extraction is widely affect the yield of the extracts. In this study four different extraction methods were used viz ultrasonic assisted extraction (UAE), soxhlet extraction (SE), microwave assisted extraction (MAE), and maceration extraction (ME) for comparison. The earlier scientists reported that pomegranate peel has high antioxidant activity than its flower, leaf and seed. The pomegranate peel extracts act as a natural inhibitors of plant pathogens like fungi and bacteria. In the present study Bhagwa, Superbhagwa and Ganesh pomegranate cultivar peels as agro waste material were used for comparative antioxidant study.
