“…(37) Several studies have revealed that constituents in JXR including Fructus Ligustri Lucidi, Radix Astragali, Rhizoma Coptidis, can ameliorate oxidative stress and exhibit antioxidant activity. (38)(39)(40) In the present study, JXR showed antioxidant defense with increased SOD activity and decreased MDA contents in diabetic rats. Therefore, the protection of diabetic retina may be through enforcing antioxidant defense.…”

In this report, we present a simple and green approach to synthesize gold nanoparticles (AuNPs) with efficient antileishmanial activity. Phytochemicals from the aqueous extract Maytenus royleanus stem were used to reduce and stabilize the gold ions into metallic nanoparticles. UV-Vis spectroscopy was employed to detect the characteristic surface plasmon resonance pattern of AuNPs (550 nm). X-ray diffraction (XRD) and energy dispersive X-ray studies were carried out to determine the crystalline nature and elemental composition of AuNPs. The surface functionalities of nanoparticles were identified with Fourier-transform infrared spectroscopy. XRD and transmission electron microscopy revealed that AuNPs were mostly hexagonal in shape with an approximate particle size of 30 nm. Significant antileishmanial activity was shown by AuNPs. AuNPs inhibited the parasite growth by 75% after 72 h of incubation. The findings of this study indicate that these nanoparticles could be an alternative, safe, and effective source of antileishmanial agents.

“…Nagajyothi et al [56] reported antioxidant activity of ZnO NPs using DPPH assay. Banerjee et al [57] performed antioxidant activity of bulk and nanostructured polyaniline nanofibers and nanostructured polyaniline fibres and showed higher free radical scavenging activity since ZnO NPs possess higher surface to volume ratio compared to its bulk form.…”

This study describes biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using agro-waste durva grass aqueous extract without uses of any hazardous chemicals and stabilizing agents. Surface plasmon resonance (SPR) band of the synthesized ZnO NPs confirmed its conversion from its metal salt to NPs by UV-vis spectroscopy. Characterization of functional groups in durva grass aqueous extract and ZnO NPs surfaces were identified by Fourier transform infrared spectroscopy (FTIR), purity and crystallinity by power x-ray diffraction analysis (XRD), size and morphology by transmission electron microscopy analysis (TEM), elemental composition by Energy Dispersive x-ray spectroscopy (EDAX), stability by thermogravimetric analysis (TGA) and dynamic light scattering (DLS) study. The synthesized ZnO NPs was highly stable with average particle size of 17 nm. The photocatalytic activity of ZnO NPs was studied under UV irradiation to methylene blue (MB) and methyl orange (MO) degradation (10 mg l −1 each). 98.1% of MB was degraded within 60 min, while 97.5% of MO within 100 min. In addition, antioxidant activity of ZnO NPs showed 91.8% free radical scavenging capacity at the dose of 250 mg l −1 which implies its importance in biomedical applications.
