Aim: The study aimed at synthesizing ZnO NPs using Petroselinum crispum extract, commonly known as parsley, as a source of biosynthesis without utilizing chemical agents for reducing, capping and stabilizing agent.

Background: Recently, the biosynthesis of nanoparticles has been widely explored due to the wide range of vital applications in nanotechnology. Biosynthesized zinc oxide nanoparticles, ZnO NPs, have become increasingly important since they have many applications and are environmentally friendly.

Methods: The innovation of this investigation is that the nanosized ZnO NPs can be formed from one-pot reaction without utilizing any external stabilizing and reducing agent which is not plausible via the current procedures.

Results: The biosynthesized ZnO NPs were characterized using UV-Vis spectroscopy, FT-IR spectroscopy, X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX) to investigate the optical, chemical, structural, and morphological properties.

Conclusion: These techniques exhibited that the property of the biosynthesized ZnO NPs is analogous with the standard NPs prepared from dissimilar methods. Investigating the plausible mechanism of formation and stabilization of ZnO NPs by biomolecules of Petroselinum crispum leaf extract was another vital feature of this study.

目的：该研究的目的是使用松香提取物（通常称为欧芹）作为生物合成来源合成 ZnO NP，而不使用化学试剂作为还原剂、封端剂和稳定剂。

背景：最近，由于纳米技术的广泛重要应用，纳米颗粒的生物合成得到了广泛的探索。生物合成的氧化锌纳米粒子 ZnO NPs 变得越来越重要，因为它们有许多应用并且对环境友好。

方法：本研究的创新之处在于纳米尺寸的 ZnO NPs 可以通过一锅反应形成，而无需使用任何外部稳定剂和还原剂，这在目前的程序中是不合理的。

结果：利用紫外-可见光谱、傅里叶变换红外光谱、X 射线衍射 (XRD)、场发射扫描电子显微镜 (FESEM)、能量色散 X 射线光谱 (EDX) 对生物合成的 ZnO NPs 进行表征，以研究其光学性质。 、化学、结构和形态特性。

结论：这些技术表明，生物合成的 ZnO NPs 的性质与由不同方法制备的标准 NPs 相似。本研究的另一个重要特征是研究由薄叶岩脂叶提取物的生物分子形成和稳定 ZnO NPs 的合理机制。
