使用植物源的纳米粒子的绿色合成已受到高度重视。在本研究中，使用 Cocous nucifera 树花序的乙酸乙酯和甲醇（EA：M 40：60）提取物合成银纳米颗粒（AgNP）。通过紫外可见分光光度计、FTIR 和 TEM 分析对合成的纳米颗粒进行了表征。经 TEM 证实，合成的 AgNP 的粒径为 22 nm。对花序提取物还原潜力的定性评估表明存在还原剂。合成的 AgNP 对人类细菌病原体（即肺炎克雷伯菌、枯草芽孢杆菌、铜绿假单胞菌和副伤寒沙门氏菌）表现出显着的抗菌活性。
Green synthesis of nanoparticles using plant source has been given much importance. In the present study, silver nanoparticles (AgNPs) were synthesized using the ethyl acetate and methanol (EA: M 40:60) extracts of the inflorescence of the treeCocous nucifera. The synthesized nanoparticles were characterized by UV–visible spectroscope, FTIR and TEM analysis. The particle size of the synthesized AgNPs was 22 nm as confirmed by TEM. The qualitative assessment of reducing potential of the extracts of inflorescence indicated the presence of reducing agents. Synthesized AgNPs exhibited significant antimicrobial activity against human bacterial pathogens viz.,Klebsiella pneumoniae, Bacillus subtilis, Pseudomonas aeruginosa and Salmonella paratyphi.
