The biosynthesis of Zinc oxide nanoparticles (ZnONPs) was done under alkaline conditions (pH 12) and temperature ≥ 80 ◦C. Mixing 10% of aqueous pomegranate peel extract (PPE) with 0.1 molar of zinc nitrate [Zn (NO3)2.6H2O], mixture was stirred at 70-80 ◦C for 15 minute and then left at room temperature overnight. The result was separated and centrifuged at 4000 rpm for 10 minutes. This process was repeated three times then the precipitate was collected and dried for using. ZnONPs were characterized by visual observation of color changes, estimate duration of synthesis compared to weight of  ZnONPs was the result, UV-visible analysis, Fourier transform infrared (FT-IR),  X- ray diffraction (XRD) and Scanning electron microscope (SEM). The results of this line, investigate the proper condition for ZnONPs synthesis. Result of FT-IR showed functional group related to Zn-O at (613.38 to 580.59 cm_1), whereas the result of X-RD at 2 theta diagnose the type of oxide formation as ZnO and determined particle size were found in range (20 - 30 nm). Finally, SEM image was shown crystals shape of ZnO nanoparticles. In conclusion, PPE acts as reducing agent used in synthesis of ZnO in Nano-scale size via easy and simple method.

To determine the free radical scavenging activity of fruit formulation mediated zinc oxide nanoparticle. Zinc oxide nanoparticles are widely known for their antimicrobial agent, anti-diabetic, anti-inflammatory, wound healing, antioxidant and optic properties. Oxidative degradation of lipids, proteins, food and cosmetics involves a radical-chain reaction with release of free radicals. These free radicals are extremely reactive and can even attack relatively stable molecules like the DNA bases. With a recent rise in diseases associated with increased oxidative stress, a good antioxidant seems to be the need of the hour.

Thermo gravimetric analysis show that Zinc Oxide nanoparticles were successfully incorporated into the polymer matrix and the Zinc Oxide copolymer composites have a good thermal stability. The micro structural analysis also show newly synthesized polymer disperse the nanoparticles well as evidenced by Scanning Electron Microscopy (SEM) analysis. The uniformly dispersed Zinc Oxide nanoparticle in the polymer matrix and the particles almost remained in their original shape and size even after incorporation in the polymer matrix. Fourier transform infrared spectroscopy (FT-IR) shift of the copolymer adsorbed Zinc Oxide nanoparticles confirmed that polymer molecules chain was anchored on the surface of the nanoparticles.

Background: Green synthesized nanoparticles (NPs) from agricultural wastes is an area of great interest due to it is eco-friendly and profitable. Zinc oxide is an inorganic UV-filter commonly used as UV-blocker in a different industry. Methods: Zinc oxide nanoparticles (ZnO NPs) were successfully biosynthesized using Zn(NO3)2 as a substrate by polyphenol enriched fraction (PEF) of pomegranate peel. The biological activity of ZnO NPs was evaluated using MBC and MIC tests for antibacterial and DPPH assay for antioxidant potential. Sunscreen potential of NPs was determined after applying them in water-in-oil emulsions. Results: UV-Vis and FT-IR spectroscopy techniques confirmed the formation of ZnO NPs. FE-SEM characterized the morphology and purity of the biosynthesized NPs with EDAX and XRD data. The average crystalline size of ZnO NPs was found to be 22 nm. FT-IR spectroscopy revealed the role of phenolic compounds in the formation and stability of ZnO NPs. The antibacterial activity of PEF and its biosynthesized ZnO was evaluated against Staphylococcus aureus and Escherichia coli. The prepared NPs showed a higher antibacterial effect than the commercial ZnO NPs. Interestingly, the antioxidant activity was also detected for obtained NPs. The PEF powder also exhibited higher antibacterial and antioxidant activity than the standards. Furthermore, the in vitro sun protection factors were estimated after applying NPs in water-in-oil emulsions. Conclusion: This study highlighted the possibility of using PEF of pomegranate peel for the biosynthesis of ZnO NPs as well as applying its NPs in sunscreens to achieve a safe alternative to harmful chemical UV-filters commonly used in cosmetics.

Abstract-In this research paper we have reported the single pot synthesis of zinc oxide nanoparticles (ZnONPs) for the first time by utilisation of leaves extract of Himalayan medicinal plant Artemisia roxburghiana. The principle of green chemistry was utilised at maximum possible level to make the synthesis not only environmentally compatible but also cost effective. The obtained nanoparticles are of good shape and size as confirmed by the instrumental techniques such as Powder XRD, HR-TEM, HR-SEM and FT-IR. The average size of the synthesized nanoparticles was between 26 to 35 nm. These nanoparticles then screened for the anti - microbial assay in which it has shown positive activity against E. coli, A. Tereus and C. falcatum. The second application of the synthesized nanoparticles is estimation of anti - oxidant activity against the DPPH. The IC value of the nanoparticles is formed to be 50 53 in EtoH while that of the standard, ascorbic acid was 26 in the same solvent.
