Citrullus colocynthis has been used to treat obesity and hyperlipidemia. Nanoparticles, due their nano size, phytochemical adsorption, improved systemic absorption high bioavailability, can potentially improve the bioactivity of C. colocynthis. The present research focused on studying effects green synthesized calcium oxide nanoparticles (CaONPs) from fruit extracts (CCFE) body weight, atheroge...
