Antioxidant, antibacterial and cytotoxic potential of silver nanoparticles synthesized using terpenes rich extract of Lantana camara L. leaves

摘要

Several attempts have been made for green synthesis of silver nanoparticles (AgNPs) using different plant extracts. Present study revealed that, antioxidant, antibacterial and cytotoxic AgNPs were synthesized using terpenes-rich extract (TRE) of environmentally notorious Lantana camara L. leaves. AgNPs were characterized by advanced techniques like UV–Visible and Infra red spectroscopy; XRD, SEM techniques as terpenes coated sphere shaped NPs with average diameter 425 nm. Further, on evaluation, AgNPs were found to exhibit dose – dependent antioxidant potential, good to moderate antibacterial activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa; and toxicity on Brine shrimp (A. salinanauplii) with LD 50 value 514.50 μg/ml. Graphical abstract Display Omitted Highlights ? Terpenes-rich extract (TRE) of Lantana camara L. leaves was prepared and evaluated. ? Silver nanoparticles (AgNP) were green synthesized using Terpenes-rich extract (TRE). ? Silver nanoparticles (AgNP) were shown to have antioxidant, antibacterial and cytotoxic potential.
