AuNPs and AgNPs synthesized from GBE exhibited free radical scavenging activity.

Notes: (A) Comparative DPPH radical scavenging activity of gallic acid, GBAgNPs, GBAuNPs, GBE, and gold and silver salts. GBAgNPs showed the highest free radical scavenging activity (93.8%) compared to GBAuNPs (81.5%) and GBE (81%). AgNPs have antimicrobial activity against Gram-negative (E. coli) and Gram-positive (S. aureus) bacterial strains. (B) Antibacterial activity of GBAgNPs of various concentrations (1, 15 μg/disk; 2, 30 μg/disk and 3, 45 μg/disk) of synthesized GBAgNPs using GBE. Neomycin was used as assay control.

Abbreviations: AgNPs, silver nanoparticles; AuNPs, gold nanoparticles; C, control; DPPH, 2,2-diphenyl-1-picrylhydrazyl; E. coli, Escherichia coli; GA, gallic acid; GBAgNPs, AgNPs from ginseng berry; GBAuNPs, AuNPs from ginseng berry; GBE, ginseng berry extract; S. aureus, Staphylococcus aureus.
