TL;DR: Investigation of the antiulcer effect of Solanum nigrum fruits extract (SNE) on cold restraint stress, gastric ulcer models and ulcer healing activity on acetic acid induced ulcer model in rats suggests that SNE was found to possess anti-ulcerogenic as well as ulcers healing properties, which might also be due to its antisecretory activity.

TL;DR: In this paper, the authors used C. viscosa extract for synthesizing silver nanoparticles which reduces silver nitrate into silver ions, and the obtained AgNPs were characterized by UV, FTIR, XRD, FESEM-EDAX and TEM analysis.
Abstract: Green synthesis of silver nanoparticles was successfully done using Cleome viscosa plant extract, simple, rapid, eco-friendly and a cheaper method. In this study, we used C. viscosa extract for synthesizing silver nanoparticles which reduces silver nitrate into silver ions. The obtained AgNPs were characterized by UV, FTIR, XRD, FESEM-EDAX and TEM analysis. They were also analyzed for their biological activities. The presence of biosynthesized AgNPs (410–430 nm) was confirmed by UV–visible spectroscopy and also crystal nature of AgNPs confirmed through XRD analysis; FT-IR spectrum was used to confirm the presence of different functional groups in the biomolecules which act as a capping agent for the nanoparticles. The morphology of AgNPs was analyzed using SEM and the presence of silver was confirmed through elemental analysis. The size of the nanoparticles was in the range of 20–50 nm determined by TEM. The green synthesized AgNPs exhibited a good antibacterial activity against both Gram negative and Gram positive bacteria. Furthermore, the green synthesized AgNPs showed reliable anticancer activity on the lung (A549) and ovarian (PA1) cancer cell lines.

TL;DR: The antibacterial property of silver nanoparticles is a beneficial application in the field of agricultural nanotechnology and the antibacterial activity of the green-synthesizedsilver nanoparticles was examined against agricultural plant pathogens.
Abstract: Utilization of biological materials in synthesis of nanoparticles is one of the hottest topics in modern nanoscience and nanotechnology. In the present investigation, the silver nanoparticles were synthesized by using the leaf and stem extract of Piper nigrum. The synthesized nanoparticle was characterized by UV-vis spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), energy dispersive X-ray analysis (EDAX), and Fourier Transform Infrared Spectroscopy (FTIR). The observation of the peak at 460 nm in the UV-vis spectra for leaf- and stem-synthesized silver nanoparticles reveals the reduction of silver metal ions into silver nanoparticles. Further, XRD analysis has been carried out to confirm the crystalline nature of the synthesized silver nanoparticles. The TEM images show that the leaf- and stem-synthesized silver nanoparticles were within the size of about 7–50 nm and 9–30 nm, respectively. The FTIR analysis was performed to identify the possible functional groups involved in the synthesis of silver nanoparticles. Further, the antibacterial activity of the green-synthesized silver nanoparticles was examined against agricultural plant pathogens. The antibacterial property of silver nanoparticles is a beneficial application in the field of agricultural nanotechnology.
