Green Synthesis of Silver Nanoparticles Using Coriander sativum Linn. Extract and Evaluating Its Antibacterial Properties

Coriander (Coriander sativum Linn.) belongs to the family Apiaceae (Umbelliferae) and is commonly known as dhanya. It has potential source of high-value components for functional foods and nutraceuticals. For centuries, the coriander plants and their parts, primarily their leaves and ripe seeds, have been used in folk medicines in addition to culinary uses. This plant is herbaceous and aromatic and is cultivated in several countries, including India, Italy, the Netherlands, Europe, China, and Bangladesh. The present study aims that a simple, rapid and economical method to synthesize silver nanoparticles (AgNPs) from Coriander sativum Linn. extract. The topical formulation was prepared by incorporation of optimized AgNPs into the carbopol gel base. Further, the gel was evaluated in vitro antibacterial assay by agar well diffusion method. The antibacterial inhibitory efficiency of prepared AgNPs incorporated nano gel was found similar to the commercial product against the Staphylococcus aureus, E. coli and Pseudomonas aeruginosa.
