The green synthesis method using plant extracts has received much attention recently owing to its eco-friendliness and economically viable nature. The plant Ipomoea pescaprae belonging to the family Convolvulacea and used in medicine for several diseases. The silver nanoparticles are synthesised by mixing the aqueous extract of fresh leaves of Ipomoea pescaprae and silver nitrate solution. The green synthesized silver nanoparticles were characterized by UV and FTIR spectroscopy and AFM techniques.The formation of silver nanoparticles was confirmed by the colour change of the sample and a strong UV absorption peak at 426nm. FTIR analysis revealed that the functional groups terpenoids , alkaloids and phenolic groups are responsible for the stabilization of AgNps. The phytochemicals present in the aqueous leaf extract acted as an effective reducing agent .The synthesized nanoparticles was evaluated for antimicrobial activities and antioxidant activities. The results showed good potential source of antimicrobial and antioxidant activities. Further investigation to isolate the pharmacologically active compounds that can be used in the production of novel drugs for various diseases would be promising.
