Since the Salvia species have been used for medicine and consist of significant bioactive compounds, Salvia absconditiflora was employed for the synthesis of silver nanoparticles. The structure of silver nanoparticles (AgNPs@sa) was determined by spectroscopic analyses. The observation of absorption at 469 nm in the UV–Vis spectrum confirmed the synthesis of AgNPs@sa. The compound moieties responsible for the reduction of silver ions were displayed by FTIR and the typical hydroxyl peak was observed at 3227 cm−1. XRD analysis displayed the signals (2θ) at 38.1°, 44.3°, 64.5°, 77.4°, and 81.5° corresponded to the peaks [111, 020, 202, 131, and 222] displaying the nanoparticles to be face-centered structure. In addition, particle size was determined by the Scherrer formula as 13.3 nm. TEM analysis presented the AgNPs@sa to be spherical with a diameter of 14.6 nm. Zeta potential measurement verified the stability of nanoparticles with the value of −36.4 mV. The observation of intense peaks at 2.5–3.6 in EDX verified the proposed structure. The activity of extract and AgNPs@sa was performed using the DPPH, ABTS, and FRAP assays. AgNPs@sa revealed an excellent ABTS effect (4.9 ± 0.1 µg/mL, IC50). Consequently, green synthesized AgNPs@sa have the potential to be employed for food and drug development.
