Launaea cornuta (wild lettuce) leaf extract: Phytochemical analysis and synthesis of silver-zinc oxide nanocomposite

Access to quality drinking water is an essential human right and a fundamental aspect of human dignity, yet a challenge to many in developing countries. Over 2 billion people worldwide lack access to quality drinking water due to microbial contamination, among other factors. Silver-doped zinc oxide impregnated activated carbon nanocomposites, Ag-ZnO-AC NCs, a strong antimicrobial agent have been used at point-of-use to treat water treatment. Green synthesis of Ag-ZnO-ACNCs has played a vital role since it leads to the acquisition of non-toxic nanocomposites compared to chemical synthesis. In this study, Ag-ZnO-AC NCs were green-synthesized using Launaea cornuta leaf extract as a source of reducing and capping agents in place of synthetic chemicals. Antioxidants from Launaea cornuta (Wild Lettuce) leaves were extracted using 0, 50, and 100% EtOH solvents with different volumes and extraction circles. The highest phenolic (11044 ± 63 µg) and antioxidant (44112 ± 894 µg) contents were extr..., XRD data was obtained through sample scanning by Rigaku XtaLAB Mini II Single-Crystal X-ray Diffractometer (427 SC) equipped with analyzer scanning mode of CuKα wavelength (λ)=1.540598 Å, 45 kV-30 mA and 2θ/θ with the spectrum range between 10 and 90 degrees and 0.026 scan step size Microbial inhibition data was obtained through lab work using well diffusion method., , # Launaea cornuta (wild lettuce) leaf extract: Phytochemical analysis and synthesis of silver-zinc oxide nanocomposite [https://doi.org/10.5061/dryad.gmsbcc2x5](https://doi.org/10.5061/dryad.gmsbcc2x5) ## Description of the data and file structure The data uploaded represent the XRD and antimicrobial test for the silver zinc oxide impregnated activated carbon used in a manuscript titled \"*Launaea cornuta (wild lettuce)* leaf extract: Phytochemical analysis and synthesis of silver-zinc oxide nanocomposite\"**.** ### Files and variables **Description:** The data in the Archive.zip file are microbial inhibition data and XRD intensity data of the silver doped zinc oxide impregnated activated carbon nanocomposites. **File name:** Elizabeth Makauk_Ag-ZnO-AC XRD data.xls * C = Carbon * AC = Activated carbon * Ag-ZnO-AC = silver zinc oxide impregnated activated carbon * 650, 750 and 850 = Carbonization temperatures **File name**: Elizabeth Makauk_Ag-ZnO-AC Antimicrobial tests results * ...获得优质饮用水是一项基本人权，亦是彰显人类尊严的核心要素，却仍是诸多发展中国家民众面临的一大难题。全球范围内，超过20亿人口因微生物污染等各类因素无法获取优质饮用水。掺银氧化锌负载活性炭纳米复合材料（Ag-ZnO-AC NCs）作为强效抗菌剂，已被用于使用点水处理环节。 相较于化学合成法，绿色合成法可获得无毒纳米复合材料，因此在该领域发挥着关键作用。本研究中，研究人员以翅颈菊（Launaea cornuta）叶提取物替代合成化学品，作为还原剂与封端剂，绿色合成了Ag-ZnO-AC NCs。 本研究采用体积与萃取循环次数各异的0%、50%、100%乙醇（EtOH）溶剂，从翅颈菊（野莴苣，Launaea cornuta）叶片中提取抗氧化成分。其中酚类物质最高含量可达(11044 ± 63) µg，抗氧化成分最高含量可达(44112 ± 894) µg，相关提取数据暂未完整呈现……X射线衍射（XRD）数据通过理学（Rigaku）XtaLAB Mini II 单晶X射线衍射仪（427 SC）采集，该仪器配备CuKα波长（λ=1.540598 Å）的分析扫描模式，工作参数为45 kV-30 mA，采用2θ/θ扫描模式，光谱扫描范围为10°至90°，步长为0.026°。 微生物抑制数据通过实验室平板打孔扩散法（well diffusion method）实验获得。 # 《翅颈菊（野莴苣）叶提取物：银氧化锌纳米复合材料的植物化学分析与合成》 [https://doi.org/10.5061/dryad.gmsbcc2x5](https://doi.org/10.5061/dryad.gmsbcc2x5) ## 数据与文件结构说明 本次上传的数据对应上述题为《翅颈菊（野莴苣）叶提取物：银氧化锌纳米复合材料的植物化学分析与合成》的手稿中所使用的掺银氧化锌负载活性炭的X射线衍射（XRD）与抗菌测试数据。 ### 文件与变量 **数据说明**：Archive.zip压缩包内的数据为掺银氧化锌负载活性炭纳米复合材料的微生物抑制数据与X射线衍射强度数据。 **文件名**：Elizabeth Makauk_Ag-ZnO-AC XRD data.xls * C：碳（Carbon） * AC：活性炭（Activated carbon） * Ag-ZnO-AC：掺银氧化锌负载活性炭（silver zinc oxide impregnated activated carbon） * 650、750与850：碳化温度（Carbonization temperatures） **文件名**：Elizabeth Makauk_Ag-ZnO-AC Antimicrobial tests results * ……
