In the present work, cone-like zinc oxide (ZnO) nanostructures (NSs) were fabricated via a simple green approach by Jatropha gossypifolia leaves extract for improving the photocatalytic and biological activity. The crystallinity and surface morphology of synthesized NPs were characterized by powder X-ray diffraction (PXRD) and transmission electron microscopic (TEM) analysis. The presence of elements in the prepared ZnO NSs was determined by the energy dispersive X-ray (EDX) spectroscopy. The photocatalytic activities of ZnO NSs were investigated by the removal of methylene blue (MB) and malachite green (MG) organic dyes under UV light irradiation. The result demonstrates that the organic dye degradation efficiency of the MG and MB was achieved at 96% and 82% under UV light irradiation. The green synthesized ZnO NSs demonstrate superior antibacterial activity against gram-positive and gram-negative bacteria's and it has excellent antioxidant ABTS free radical scavenging activity. The inhibition of denaturation of protein and proteinase inhibitory was studied by anti-arthritic activity.
