Abstract
Biosynthesized Nanoparticles especially from plants are a new research trend nowadays. In this study, green biosynthesis of silver nanoparticles (TCAgNPs) employing Trichosanthes cucumerina methanol leaf extract was realized. The antioxidant and anti-inflammatory activities of both the methanol extract of T. cucumerina and TCAgNPs were carried out and compared. Indomethacin and ascorbic acid were employed as a positive control for these activities respectively. Fourier transform infrared spectroscopy (FT-IR) scanning electron microscopy (SEM) and Ultraviolet-visible spectroscopy were employed to characterize the formation of TCAgNPs. The TCAgNPs showed absorption bands at around 340-440 nm which is a distinctive band for Ag Nanoparticles and functional groups accountable for Ag nanoparticles synthesized by plants were noticed in the FTIR. TCAgNPs were spherical in morphology as seen from the SEM images. TCAgNPs displayed better antioxidant and anti-inflammatory activities at 400 ug/ml (9.79±0.58) as compared with its polar extracts (7.74±0.58) but both the polar part (52.06±1.27) and TCAgNPs (61.72±2.54) were better in anti-inflammatory activity when compared with the positive control indomethacin (antiinflammatory) (48.30±0.23). This study revealed that AgNPs from plants can find germaneness in food, drugs, environmental sciences and drugs.

UV – Vis spectroscopy was further employed to examine the AgNPs formed, it was discovered that Figure 3 shows the curve in each spectrum of produced silver nanoparticles that were absorbed in the wavelength range of 420-440 nm for silver nanoparticles but 440 nm for T. cucumerina
Fourier transform infrared spectroscopy (FT-IR) Spectroscopy Study Fourier Transform Infrared Analysis (FTIR) spectroscopy studies were utilized to identify and describe the biological reduction functional group, which will reveal the likely group of organic compounds found in these underappreciated vegetables that are responsible for the reduction of Ag+ ions to elemental Ag0 and resulting in the successful stabilization of the silver nanoparticles
Summary
Cucurbitaceae, known as melons, gourds, or cucurbits, is a plant family that includes, squashes, melons (including watermelons) and luffas, cucumbers (including pumpkins). Characterization of Silver Nanoparticles TC-AgNPs with the leaves’ extract was characterized employing techniques such as Ultra-violet/Visible (UV-vis), Fourier Transform Infrared (FTIR) and Scanning electron microscopy (SEM). Fourier Transform Infrared Analysis (FTIR) The FTIR analysis was done for the nanoparticles formed and the extracts of these plants were viewed employing the equipment and its software reported earlier by Bello et al, (2019, 2020). Scanning Electron Microscopy (SEM) The nanoparticles of these plants’ extracts were viewed employing the equipment and its software reported earlier by Bello et al, (2019, 2020). UV – Vis spectroscopy was further employed to examine the AgNPs formed, it was discovered that Figure 3 shows the curve in each spectrum of produced silver nanoparticles that were absorbed in the wavelength range of 420-440 nm for silver nanoparticles but 440 nm for T. cucumerina. This peak falls within the nanoparticle specification range (Figure 1)
