摘要

本研究以石榴皮、艾草、洋甘菊和山茶为原料制备二氧化锰纳米颗粒，并对其抑菌活性进行了研究。采用紫外-可见分光光度计(UV -Vis)、ZP电位(ZP)和x射线衍射(XRD)分析了植物提取物中植物化学物质的存在。利用植物提取物制备二氧化锰纳米颗粒有其独特的特点。制备的MnO2 NPs平均晶粒尺寸为14.22 ~ 21.0 nm, zeta电位值分别为-23.6、-20.04、-25.6、-16.7 mV。二氧化锰纳米颗粒(MnO2 NPs)对真菌和多种革兰氏阳性和革兰氏阴性细菌具有显著的抗菌活性。研究结果表明，以石榴皮、白藻皮为原料合成MnO2 NPs。对细菌和真菌的抑制作用最高，而洋甘菊和洋甘菊提取物的抑菌活性较低

Green Synthesis of Manganese Dioxide Nanoparticles and its Biological

The goal of this research is to prepare Manganese dioxide (MnO2) nanoparticles from plant extracts (Puncia granatum L peel, Artemsiai herba-alba Asso, Matricaria chamomilla L, and Camellia sinensis) and test their antibacterial activity. To evaluate the presence of phytochemicals in plant extracts, were used UV-Visible spectrophotometer analysis (UV– Vis), Zeta potential (ZP), and X-ray Diffraction (XRD). The production of MnO2 nanoparticles by plant extracts was shown to have distinctive features. The average crystallite size of manufactured MnO2 NPs was calculated to be between 14.22-21.0 nm, with zeta potential values -23.6, -20.04, -25.6, -16.7 mV, respectively. Manganese dioxide nanoparticles (MnO2 NPs) have significant antibacterial activity against fungi and diverse gram-positive and gram-negative bacteria. The findings results showed that the synthesized MnO2 NPs by P granatum L peel, A herba-alba Asso. plants had the highest percentage of bacterial and fungi inhibition, while M. chamomilla L.and C. sinensis extracts showed lower antifungal activity
