We would like to report the eco-friendly synthesis of reduced graphene oxide using aqueous extract of Acorus calamus (rhizome), dried fruit and seed parts of Terminalia bellirica, Helicteres isora and Quercus infectoria and the whole shell part of Turbinella pyrum by simple steam bath technique. The structural and morphological characteristics of prepared reduced graphene oxides were determined by UV–Visible spectroscopy, Fourier Transform Infra-Red spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM) and Raman spectroscopy. The Surface Plasmon Resonance at 260–280 nm ensured the reduced graphene oxide formation. The antibacterial efficacy of synthesized reduced graphene oxide was evaluated against both gram-positive and gram-negative pathogens such as Staphylococcus aureus, Bacillus subtilis, Salmonella paratyphi and Escherichia coli. Among the selected samples Quercus infectoria mediated reduced graphene oxide showed excellent inhibition efficiency (27 and 28 mm) against Escherichia coli and Staphylococcus aureus, respectively as compared to the standard Gentamycin (29 mm). Quercus infectoria showed significant inhibition of 22 mm and moderate inhibition of 18 mm against Bacillus subtilis and Salmonella paratyphi, respectively. The results suggest selected plants and chank shell-mediated reduced graphene oxide as potential antibacterial agents for various therapeutic applications.

我们想报道利用石菖蒲（根茎）的水提取物、榄仁树、Helicteres isora 和 Quercus infectoria的干果和种子部分以及Pyrum的整个壳部分通过简单的蒸汽浴来环保合成还原氧化石墨烯技术。通过紫外-可见光谱、傅里叶变换红外光谱（FTIR）、场发射扫描电子显微镜（FESEM）和拉曼光谱测定了制备的还原氧化石墨烯的结构和形态特征。260-280 nm 的表面等离子共振确保了氧化石墨烯的形成减少。评估了合成的还原氧化石墨烯对革兰氏阳性和革兰氏阴性病原体（例如金黄色葡萄球菌、枯草芽孢杆菌、副伤寒沙门氏菌和大肠杆菌）的抗菌功效。在选定的样品中，与标准庆大霉素（29mm）相比，没食子栎介导的还原氧化石墨烯分别对大肠杆菌和金黄色葡萄球菌表现出优异的抑制效率（27和28mm）。没食子栎对枯草芽孢杆菌和副伤寒沙门氏菌分别具有显着抑制作用22mm和中度抑制作用18mm 。结果表明，选定的植物和长壳介导的还原氧化石墨烯可作为各种治疗应用的潜在抗菌剂。
