The present research focused on extraction of bioactive compounds from Woodfordia fruticosa flower (WF) using ethanol, methanol and ethyl acetate as solvents and the development of silver nanoparticles using these extracts for inhibition of (), (), (), and Bacillus cereus (B. cereus) bacteria. The functional groups of bioactive compounds present in the solvent extracts were characterized using Fourier transform infrared spectroscopy (FT-IR). The morphological features and formation of silver nanoparticles (10-30 nm, by the reduction of solvent extracts) were evaluated using scanning electron microscopy (SEM) and ultraviolet-visible (UV-Vis) spectroscopy, respectively. The elemental compositions of the synthesized nanoparticles were analyzed using energy-dispersive X-ray spectroscopy (EDX). The inhibition efficiency of the alcoholic and ester extracts of WF and the synthesized silver nanoparticles were evaluated and compared to Moxifloxacin. The results revealed that the synthesized silver nanoparticles demonstrated enhanced bacterial inhibition efficiency compared to the unprocessed ethanol, methanol, and ethyl acetate extracts of WF, and Moxifloxacin.
本研究聚焦于以乙醇、甲醇和乙酸乙酯为溶剂，从水红木花（WF）中提取生物活性化合物，并利用这些提取物制备银纳米颗粒，以抑制（）、（）、（）和蜡样芽孢杆菌（B. cereus）。使用傅里叶变换红外光谱（FT-IR）对溶剂提取物中存在的生物活性化合物的官能团进行了表征。分别使用扫描电子显微镜（SEM）和紫外可见（UV-Vis）光谱对银纳米颗粒（通过溶剂提取物还原形成，粒径为10 - 30nm）的形态特征和形成情况进行了评估。使用能量色散X射线光谱（EDX）分析了合成纳米颗粒的元素组成。评估并比较了WF的醇提取物和酯提取物以及合成银纳米颗粒与莫西沙星的抑菌效率。结果表明，与未处理的WF乙醇、甲醇和乙酸乙酯提取物以及莫西沙星相比，合成的银纳米颗粒表现出更高的细菌抑制效率。
