Green Synthesis of Gold Nanoparticles Using Salvia rosmarinus Essential Oil

The project was centered on the utilization of essential oils extracted from Salvia rosmarinus Spenn. for the synthesis and stabilization of gold nanoparticles. This approach is noteworthy due to the distinctive properties exhibited by gold nanoparticles in contrast to bulk gold. Moreover, these properties can be influenced by the size and shape of the nanoparticles. The essential oil was extracted from S. rosmarinus through the process of hydrodistillation using a Clevenger type apparatus. A GC-MS analysis of these essential oils revealed the presence of several compounds, with the most frequently identified ones being -pinene (۱۶.۷%), ۱,۸-cineole (۸.۶%), camphor (۱۰%), and borneol (۷.۷%). Subsequently, these obtained essential oil was employed as both a regenerating agent and stabilizer in the synthesis of gold particles. The resultant nanoparticles underwent identification and characterization using standard methods. They exhibited a face-centered cubic crystal structure and possessed an average size of ۲۶.۶ nm. Remarkably, it was ascertained that the essential oils of S. rosmarinus are proficient in regenerating gold ions and stabilizing them in the form of stable colloidal nanoparticles. This development holds promise for various applications, including the production and formulation of diverse products such as cosmetics and health-related items.
