The present work deals with the synthesis of zinc oxide (ZnO) nanoparticles (Nps) using the biocompounds extracted from leaves (MD L.) and zinc acetate as precursors. The choice of the precursors was based on the intention to use the synthesised ZnO Nps for the healthcare applications. In this line, the antimicrobial property of ethanolic extract of MD L., uncalcined ZnO Nps and calcined ZnO Nps has been assessed and compared. The prepared particles have been characterised by comparing their Fourier transform infrared spectrum, X-ray diffraction (XRD) diffractogram and TEM images. The presence of ZnO has been confirmed using IR spectrum. The crystal structure and crystallite size have been found out using XRD diffractogram, and the obtained crystallite size was confirmed using TEM images. Finally, an attempt has been made to correlate the structure with the antimicrobial property of the material.
本研究以从叶（MD L.）中提取的生物化合物和醋酸锌为前驱体，进行氧化锌（ZnO）纳米颗粒（Nps）的合成。选择这些前驱体是基于将合成的ZnO纳米颗粒用于医疗保健应用的目的。为此，对MD L.乙醇提取物、未煅烧的ZnO纳米颗粒和煅烧的ZnO纳米颗粒的抗菌性能进行了评估和比较。通过比较所制备颗粒的傅里叶变换红外光谱、X射线衍射（XRD）图谱和透射电子显微镜（TEM）图像对其进行了表征。利用红外光谱确认了ZnO的存在。通过XRD图谱确定了晶体结构和微晶尺寸，并利用TEM图像对所得微晶尺寸进行了确认。最后，尝试将材料的结构与抗菌性能相关联。
