“…These processes are classied in green chemistry. [1][2][3][4] Using plant extracts in the green synthesis of nanoparticles is one of the cleanest, biocompatible, nontoxic and eco-friendly methods used for large-scale production. 5,6 Polyol components present in plant extracts such as coffee powder extract can act as chelating and capping agents for rapid biosynthesis of nanoparticles and stabilize the metallic nanoparticles formed.…”

Pterocarpus santalinus is valued for its strong, dark-purple, bitter heartwood. The gentle aroma of P. santalinus heartwood is caused by the presence of terpenoids, which gives it its color and fragrance. P. santalinus heartwood dye is used as a light microscopy stain, and as a coloring agent in pharmaceutical preparations. The Antibacterial, antimicrobial, and UV-blocking capabilities of ZnO NPs are outstanding compared with other metal oxides. The study aims to analyze the antiinflammatory and antifungal activity of zinc oxide nanoparticles using red sandalwood extract. A plant extract sample was taken and 100ml of distilled water was added. Heated at 50°C for 5-10 minutes. The heated solution was filtered. .0.861g of zinc oxide was measured and dissolved in 70 ml of distilled water. The mixture was transferred to extract the sample. The solution was heated and labeled. The heating mantle was used with a temperature of 50-60°C and the time took was 6-8 minutes. The results obtained were statistically analyzed using spearman correlation analysis and using SPSS software. The sample shows an increasing absorbance rate and increases in the zone of inhibition with the increase in the concentration of the extract. It also showed an effective antifungal activity against C.albicans. The correlation analysis is statistically significant with p value<0.05. From the present study, it is concluded that red sandal-mediated zinc oxide nanoparticles possess anti-inflammatory and antifungal activity.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-Share Alike 4.0 License, which allows others to remix, tweak, and build upon the work non commercially, as long as the author is credited and the new creations are licensed under the identical terms.

“…Nanomaterials, materials with small sizes in the range of 1-100 nm and a higher specific surface area appropriate for catalysis, are synthesized with controllable sizes and morphologies affecting the photocatalytic activity. Physical and chemical synthesis methods have been developed for manufacturing ZnO nanoparticles, such as co-precipitation [2], sol-gel [3], hydrothermal [4], ball milling [5], microwave assistance [6], and green synthesis using plant extracts [7,8]. Green synthesis is the best route for manufacturing ZnO nanoparticles because it can produce nanoparticles with small size and large surface area and protect the environment from hazardous chemicals.…”

“…The green synthesis of ZnO nanoparticles using various parts of plants, including stems of Euphorbia tirucalli (pencil cactus) [7], which was found to be very effective in degrading 85.3% of rhodamine B dye for 210 minutes irradiation, and lychee peel extract that could effectively remove 98% of congo red dye from wastewater within 2 hours of contact time [13] have been reported. Furthermore, preparation of ZnO nanoparticles using extract of Alchemilla vulgaris leaves which can degrade 75% of rhodamine B dye after irradiating for 2 hours [14], extract of dragon fruit peel (Hylocereus polyrhizus [15] that has 95% degradation efficiency toward methylene blue dye after irradiating under sunlight for 2 hours, and white dragon fruit (Hylocereus undatus) peel that could be used as a potent antimicrobial agent [16], also have been reported in literature.…”

Zinc oxide (ZnO) nanoparticles have been successfully synthesized using water extract of red dragon fruit (Hylocereus polyrhizus) stem with zinc acetate dihydrate as a precursor of ZnO. Chemical compounds contained in the red dragon fruit stem extract, such as phenolics, terpenoids, and steroids, acted as reducing agents, stabilizers, and capping agents. The phase structure, crystallite size, functional groups, shape, and morphology of ZnO nanoparticles were determined by X-ray diffraction (XRD), Fourier Transform infrared (FT-IR) Spectroscopy, and Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The XRD pattern confirmed the crystallinity of synthesized zinc oxide was in the zincite (ZnO) phase with an average crystallite size of 79.09 nm. Spectroscopy FTIR analysis showed that the synthesized ZnO nanoparticles had characteristics similar to the ZnO standard/commercial. SEM-EDX analysis revealed that the synthesized ZnO nanoparticles were spherical, evenly distributed, and homogeneous particle size. The photocatalytic activity of synthesized ZnO nanoparticles was evaluated on the photodegradation of naphthol blue black (NBB) dye. The results showed that the synthesized ZnO nanoparticles have high photocatalytic activity that can degrade NBB dye up to 98.82%. This high photocatalytic activity was obtained at operating parameter conditions with the initial pH of NBB at 2, the dosage of ZnO nanoparticles at 250 mg, and the initial dye concentration at 10 ppm.
