AN ECO-FRIENDLY APPROACH FOR SYNTHESIS OF SILVER NANOPARTICLES USING Ipomoea Pes-Caprae ROOT EXTRACT AND THEIR ANTIMICROBIAL PROPERTIES

摘要

objective: Silver nanoparticles (AgNPs) were obtained through green synthesis using Ipomoea pes-caprae root extract for the first time. The active biomolecules present in the roots of I. pes-caprae, are ergoline alkaloids, indolizidine alkaloids, benzenoids and phenolic compounds act as both the reduction and stabilization of AgNPs. Methods: The synthesized nanoparticles were characterized using UV-Visible spectroscopy, Fourier transform infra-red spectroscopy, transmission electron microscope (TEM). Results: A peak at 400 nm was obtained in UV-Visible spectroscopy confirmed the formation of AgNPs. TEM microgram confirms that AgNPs were in the nano range and spherical in nature, the size was observed to be 50 nm. Conclusion: A higher zone of inhibition was observed in the AgNPs synthesized from the root extract of I. pes-caprae because of the active biomolecules capped on the AgNPs that has greater efficacy against bacteria.
