Abstract
In this study, silver nanoparticles (AgNPs) were synthesized
using Lilium ciliatum leaf extract obtained through supercritical CO₂
extraction (SFE-CO₂). In the green synthesis approach, plant materials utilize
their biological extracts as reducing and capping agents, making the process
highly economical because it significantly lowers the overall cost of synthesis
(1). Leaves collected from Haçkalı Baba Plateau (Trabzon, Türkiye) was dried,
mechanically fragmented, and subjected to SFE at 150 bar and 40 °C to obtain a
phytochemically rich extract. Aqueous solutions of the extract at 2% (w/v)
concentration were mixed in volumes of 0.1–6 mL with AgNO₃ solutions prepared
in the range of 0.01–10 mM. The reaction mixtures were subjected to microwave
irradiation at 90 W for 1–60 minutes, during which the appearance of a
characteristic yellow color indicated the formation of silver nanoparticles.
UV-Visible spectroscopy in the range of 300–800 nm was employed to confirm the
synthesis of AgNPs by monitoring the surface plasmon resonance (SPR) bands
characteristic of silver nanoparticles (2). This study demonstrates the
potential of Lilium ciliatum leaf extract as a natural reducing and
stabilizing agent in green nanoparticle synthesis and provides an effective
microwave-assisted approach for the rapid and environmentally friendly
production of AgNPs.
