Abstract

This study investigates the eco-friendly synthesis of calcium carbonate nanoparticles (CaCO3 NPs) from waste fruit peels using drying, calcination, and controlled precipitation methods. The synthesized nanoparticles were confirmed for their chemical composition and functional groups using Fourier Transform Infrared Spectroscopy (FTIR). The biological and pharmaceutical potential of the nanoparticles were evaluated through in vitro assays, including antioxidant activity using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method, anti-inflammatory activity through protein denaturation assay, and antacid activity via acid neutralization studies. This work emphasizes the valorization of fruit peel waste as a sustainable resource for the synthesis of calcium carbonate nanoparticles and explore their potential relevance in pharmaceutical and biomedical applications.

Keywords: Calcium Carbonate Nanoparticles, Fruit Peels Waste, Green Synthesis, FTIR Characterization, Antioxidant Activity, Anti-Inflammatory Activity, Antacid Property.
