Here presented a quick and easy synthesis of copper nanoparticles (CuNPs). Pistachio hull extract has been used as a reducing and stabilizing agent in the preparation of CuNPs. This biosynthesis is a kind of supporter of the environment because chemical agents were not used to making nanoparticles, and on the other hand, it prevents the release of pistachio waste in nature and its adverse effects on nature. The biosynthesized CuNPs and CuNPs/silver Schiff base nanocomposite (CSS NC) were characterized by UV-VIS spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDS). CuNP and CSS NC antimicrobial activity was examined by both well diffusion and determination MIC methods against four bacteria Staphylococcus aureus, Bacillus cereus, Escherichia coli, and Pseudomonas aeruginosa and two fungi Aspergillus Niger and Candida albicans. CuNPs and CSS NC showed significant antimicrobial activity on the samples, preventing the growth of bacteria and fungi at very low concentrations. CuNPs and CSS NC had the greatest effect on Escherichia coli bacteria and Aspergillus niger fungi. Phenolic compounds are one of the most important antioxidants that are involved in various fields, including pharmacy. Pistacia vera hull is a rich source of phenolic compounds. In this study, the most phenolic compound in Pistacia vera hull is gallic acid and rutin, which has been identified by HPLC analysis. In this study, Pistacia vera hull essential oil analysis was performed by the GC-MS method, in which α-pinene, D-limonene, and isobornyl acetate compounds constitute the highest percentage of Pistacia vera hull essential oil.

利用黄连木生物合成有机纳米复合材料：一种高效抗菌剂

这里介绍了铜纳米颗粒 (CuNP) 的快速简便合成方法。开心果壳提取物已被用作 CuNP 制备中的还原剂和稳定剂。这种生物合成是一种环境的支持者，因为制造纳米颗粒时不使用化学试剂，另一方面，它防止了开心果废物在自然界中的释放及其对自然的不利影响。通过紫外-可见光谱、傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)、场发射扫描电子显微镜(FE-SEM)对生物合成的CuNPs和CuNPs/银席夫碱纳米复合材料(CSS NC)进行了表征和能量色散 X 射线光谱 (EDS)。通过良好扩散和MIC测定方法，检测了CuNP和CSS NC对四种细菌金黄色葡萄球菌、蜡状芽孢杆菌、大肠杆菌和铜绿假单胞菌以及两种真菌黑曲霉和白色念珠菌的抗菌活性。CuNP 和 CSS NC 对样品表现出显着的抗菌活性，在极低浓度下可防止细菌和真菌的生长。CuNPs和CSS NC对大肠杆菌和黑曲霉的影响最大。酚类化合物是最重要的抗氧化剂之一，涉及各个领域，包括制药。黄连木壳是酚类化合物的丰富来源。在本研究中，黄连木壳中最多的酚类化合物是没食子酸和芦丁，并通过 HPLC 分析进行了鉴定。本研究采用GC-MS法对黄连木精油进行分析，其中α-蒎烯、D-柠檬烯和乙酸异冰片酯化合物在黄连木精油中所占比例最高。
