Phytoconstituents presenting in herbal plant broths are the biocompatible, regenerative, and cost-effective sources that can be utilized for green synthesis of silver nanoparticles. Different plant extracts can form nanoparticles with specific sizes, shapes, and properties. In the study, we prepared silver nanoparticles (P.uri.AgNPs, P.zey.AgNPs, and S.dul.AgNPs) based on three kinds of leaf extracts ( and , respectively) and demonstrated the antifungal capacity. The silver nanoparticles were simply formed by adding silver nitrate to leaf extracts without using any reducing agents or stabilizers. Formation and physicochemical properties of these silver nanoparticles were characterized by UV-vis, Fourier transforms infrared spectroscopy, scanning electron microscope, transmission electron microscope, and energy dispersive X-ray spectroscopy. P.uri.AgNPs were 28.3 nm and spherical. P.zey.AgNPs were 26.7 nm with hexagon or triangle morphologies. Spherical S.dul.AgNPs were formed and they were relatively smaller than others. P.uri.AgNPs, P.zey.AgNPs and S.dul.AgNPs exhibited the antifungal ability effective against and demonstrating their potentials as fungicides in the biomedical and agricultural applications.
草药植物汤中存在的植物成分是具有生物相容性、可再生且经济高效的来源,可用于银纳米颗粒的绿色合成。不同的植物提取物可以形成具有特定尺寸、形状和性质的纳米颗粒。在这项研究中,我们基于三种叶提取物(分别为 和 )制备了银纳米颗粒(P.uri.AgNPs、P.zey.AgNPs 和 S.dul.AgNPs),并展示了其抗真菌能力。银纳米颗粒是通过将硝酸银添加到叶提取物中简单形成的,无需使用任何还原剂或稳定剂。通过紫外可见光谱、傅里叶变换红外光谱、扫描电子显微镜、透射电子显微镜和能量色散X射线光谱对这些银纳米颗粒的形成和物理化学性质进行了表征。P.uri.AgNPs 为 28.3 纳米且呈球形。P.zey.AgNPs 为 26.7 纳米,具有六边形或三角形形态。形成了球形的 S.dul.AgNPs,且它们相对比其他的更小。P.uri.AgNPs、P.zey.AgNPs 和 S.dul.AgNPs 表现出对 和 有效的抗真菌能力,证明了它们在生物医学和农业应用中作为杀菌剂的潜力。
