利用环境可接受的植物提取物实现了银纳米颗粒的绿色合成。观察到在15分钟的反应时间内，Abutilon indicum叶提取物可以将银离子还原成银纳米颗粒。通过紫外-可见分光光度计分析监测胶体溶液中还原银纳米颗粒的形成和稳定性。由XRD图计算银纳米颗粒的平均粒径。确定纳米颗粒形成后叶提取物的FT-IR光谱，以鉴定负责金属离子转化为金属纳米颗粒的可能官能团。由此获得的AgNPs对革兰氏阳性（金黄色葡萄球菌和枯草芽孢杆菌）和革兰氏阴性（伤寒沙门氏菌和大肠杆菌）微生物显示出高效的抗菌活性。(C)2014爱思唯尔有限公司版权所有。
Green synthesis of silver nanoparticles has been achieved using environmentally acceptable plant extract. It is observed that Abutilon indicum leaf extract can reduce silver ions into silver nanoparticles within 15 min of reaction time. The formation and stability of the reduced silver nanoparticles in the colloidal solution were monitored by UV-Vis spectrophotometer analysis. The mean particle diameter of silver nanoparticles was calculated from the XRD pattern. FT-IR spectra of the leaf extract after the development of nanoparticles are determined to allow identification of possible functional groups responsible for the conversion of metal ions to metal nanoparticles. The AgNPs thus obtained showed highly potent antibacterial activity toward Gram-positive (Staphyloccocus aureus and Bacillus subtilis) and Gram-negative (Salmonella typhi and Escherichia coli) microorganisms.
