Essential oils (EOs) which cover about 91% whole biomolecules formulated from leaves based on Gas chromatography-mass spectrometry were employed to identify structures. EOs were observed as good agents in the preparation of Silver nanoparticles (AgNPs) through the proposed mechanism that was attempted to interpret the pathway of the bio-preparation process. The characterization of EOs-AgNPs carried via ultraviolet-visible to reveal surface plasmon resonance at 420 nm, Fourier transform infrared to observe functional groups EOs compared to EOs-AgNPs. X-ray diffraction (XRD) revealed a broad chart owing to the small size of AgNPs in average size less than 10 nm calculated relying on image J software, spherical AgNPs with a small dispersive size observed by transmission electron microscopy. Quasi near spherical surface morphology of EOs-AgNPs had detected by field emission scanning electron microscope. EOs-AgNPs were assessed for their antibacterial potential against both Gram-positive () and Gram-negative () bacteria as suppressing bacterial agents. EOs-AgNPs had their anti-breast cancer MCF-7 cell line ability investigated by DNA fragmentation; cycle flow cytometry (apoptosis) at half maximal inhibitory concentration (IC) was determined at 260 µg/mL which has been stated by cytotoxicity (MTT) assay. EOs-AgNPs have antibacterial and anticancer therapeutic potential, and it is safe, inexpensive, and scalable in the nanoscale range.
基于气相色谱 - 质谱法,从叶子中提取的约占整个生物分子91%的精油(EOs)被用于鉴定结构。通过所提出的机制,观察到EOs在制备银纳米颗粒(AgNPs)方面是良好的试剂,该机制试图解释生物制备过程的途径。通过紫外 - 可见光谱对EOs - AgNPs进行表征,以揭示在420nm处的表面等离子体共振,通过傅里叶变换红外光谱观察与EOs - AgNPs相比的EOs官能团。X射线衍射(XRD)显示出一个宽图谱,这是由于根据Image J软件计算得出的平均尺寸小于10nm的AgNPs尺寸较小,通过透射电子显微镜观察到具有小分散尺寸的球形AgNPs。通过场发射扫描电子显微镜检测到EOs - AgNPs的准近球形表面形态。评估了EOs - AgNPs对革兰氏阳性()和革兰氏阴性()细菌作为抑菌剂的抗菌潜力。通过DNA片段化研究了EOs - AgNPs对乳腺癌MCF - 7细胞系的抗癌能力;通过细胞毒性(MTT)测定法确定在半最大抑制浓度(IC)下的循环流式细胞术(凋亡)为260μg/mL。EOs - AgNPs具有抗菌和抗癌治疗潜力,并且在纳米尺度范围内是安全、廉价且可扩展的。
