Green synthesis of Nanomaterials from plant sources Cucurbitaceae family "Pumpkin

Abstract

The aim of our study is to conduct green synthesis of zinc oxide and silver nanoparticles from natural plant sources, specifically from pumpkin (Cucurbita moschata) belonging to the Cucurbitaceae family, due to its therapeutic potential and biological activities, and its applications in various fields. In our experimental study, after extracting oil from pumpkin seeds with a yield of 1.611%, we assessed its value for the presence of biologically active compounds that give it high therapeutic potential, nutritional value, and health benefits such as linoleic acid, palmitic acid, and oleic acid. We characterized the materials synthesized from pumpkin seeds and leaves using color change, UV-VIS, FTIR, EDX/SEM, and DRX. The results showed that the synthesized materials had hexagonal and cubic shapes, ranging in size from 10,000 nm to 50,000 nm, exhibiting antibacterial activity against types of bacteria: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Bacillus subtilis..
