Abstract

Herein, we report our success synthesizing silver nanoparticles (AgNPs) using aqueous extracts from the leaves and flowers of growing in the geothermal manifestation Ie Seu-Um, Aceh Besar, Indonesia. aqueous extract can be used as a bio-reductant for Ag→Ag conversion, obtained by 48h incubation of Ag, and the extract mixture in a dark condition. UV-Vis characterization showed that the surface plasmon resonance (SPR) peaks of AgNPs-leaf (AgNPs-LCg) and AgNPs-flower (AgNPs-FCg) appeared in the wavelength range of 410-460 nm. Scanning electron microscopy energy-dispersive X-ray spectrometry (SEM-EDS) revealed the agglomeration and spherical shapes of AgNPs-LCg and AgNPs-FCg with diameters ranging from 87.85 to 256.7 nm. Zeta potentials were observed in the range of -41.8 to -25.1 mV. The Kirby-Bauer disc diffusion assay revealed AgNPs-FCg as the most potent antimicrobial agent with inhibition zones of 12.05 ± 0.58, 11.29 ± 0.45, and 9.02 ± 0.10 mm for , , and , respectively. In conclusion, aqueous extract from the leaves or flowers of may be used in the green synthesis of AgNPs with broad-spectrum antimicrobial activities.

摘要

在此，我们报告了成功地使用印度尼西亚亚齐 Besar 地区 Ie Seu-Um 地热显示区生长的叶子和花的水提物合成银纳米粒子 (AgNPs)。水提物可作为 Ag→Ag 转化的生物还原剂，通过在黑暗条件下将 Ag 和提取混合物孵育 48 小时得到。UV-Vis 特征表明，AgNPs-叶 (AgNPs-LCg) 和 AgNPs-花 (AgNPs-FCg) 的表面等离子体共振 (SPR) 峰出现在 410-460nm 的波长范围内。扫描电子显微镜能谱 (SEM-EDS) 显示 AgNPs-LCg 和 AgNPs-FCg 呈团聚状和球形，直径范围为 87.85-256.7nm。Zeta 电位在-41.8 至-25.1mV 范围内。Kirby-Bauer 圆盘扩散试验表明，AgNPs-FCg 是最有效的抗菌剂，对 、 、 的抑菌圈直径分别为 12.05±0.58mm、11.29±0.45mm 和 9.02±0.10mm。总之， 叶子或花的水提物可用于绿色合成具有广谱抗菌活性的 AgNPs。
