摘要

我们目前的研究描述了使用堇青石（AC）的叶提取物绿色合成氧化铜纳米颗粒（CuONPs）。植物化学分析证实了植物提取物中存在黄酮、皂苷和生物碱，这些化学物质可作为还原剂、稳定剂和封端剂。采用紫外-可见分光光度法、XRD、FT-IR和SEM-EDS对CuONPs进行了表征。生物合成的CuONPs的UV-Vis光谱显示在325nm处有吸收峰。XRD图还显示，Debye Scherrer公式观察到约43.47nm的平均结晶尺寸。EDS分析证实了CuONPs的组成和纯度。根据FT-IR分析，官能团-OH、C=O和C-O的存在触发了CuONPs的合成。此外，CuONPs的抗氧化性能抑制了作为抗氧化剂的自由基，IC50值为34.20g/mL。

Green synthesis of copper oxide (CuO) nanoparticles using Anredera cordifolia leaf extract and their antioxidant activity

Our present study describes the green synthesis of copper oxide nanoparticles (CuONPs) using a leaf extract from Anredera cordifolia (AC). The presence of flavonoids, saponins, and alkaloids in the plant extract was confirmed by phytochemical analysis, and these chemicals can be used as reducing, stabilizing, and capping agents. UV-Vis Spectrophotometry, XRD, FT-IR, and SEM-EDS were used to characterize the CuONPs. The UV-Vis spectroscopy of the biosynthesized CuONPs revealed an absorption peak at 325 nm. The XRD graph also revealed that the Debye-Scherrer formula observed an average crystalline size of around 43.47 nm. EDS analysis confirmed the composition and purity of CuONPs. The presence of functional groups -OH, C=O, and C-O triggers the synthesis of CuONPs, according to FT-IR analysis. Furthermore, the CuONPs antioxidant property inhibited free radicals as antioxidants with an IC50 value of 34.20 g/mL.
