Antimicrobial Activity of Curcuma longa Rhizome Ethanolic Extract Mediated Sonicated Biogenic Bismuth- Silver Oxide Nanocomposites: Characterization and Isolation of Turmeric Oil from Rhizomes.
Abstract
Curcuma longa is also known as turmeric which is a popular medicinal spice used in cooking and treatment of diseases in India. Nanoparticles synthesized using natural products have gained attraction due to their cost- effectiveness and environmental compatibility. Silver Oxide and Bismuth nanoparticles have been synthesized and have been studied for their applications in biotechnology. In this study, a combination of bismuth and silver oxide nanoparticles have been synthesized using the ethanolic extract of C. longa and have been evaluated for their antimicrobial applications. The antimicrobial activity of the nanocomposites were successfully verified as against 7 out of 8 bacterial pathogens. The ethanolic extract of the turmeric rhizomes was characterized preliminary for the presence of steroids, terpenoids and volatile organic carbons. The UV- Vis, FT- IR spectroscopies and GC- MS of turmeric oil were employed to study the components of turmeric oil obtained via heating. Subsequently the extraction protocol was optimized without heating and HPTLC fingerprinting of turmeric oil isolated from ethanolic extract of turmeric rhizomes without heating were carried out. It is assumed that the essential oil isolated from the ethanolic extract of turmeric rhizomes acted as a reducing agent in fabrication and formation of the nanocomposites.
