In this paper, we describe a green technique for the manufacture of Zinc oxide (ZnO) nanoparticles from aqueous extracts of Hybanthus enneaspermus (L.) F. Muell leaves, stems, and roots. Although the H. enneaspermus plant has been employed in India’s traditional medicine system, it has yet to be evaluated for the production of zinc oxide nanoparticles. Zinc Nitrate hexahydrate [Zn(NO3)2.6H2O] solution was used to make the nanoparticles. The Zinc Nitrate solution was lowered after being exposed to the herbal extracts, and nanoparticles were formed. The colour change in the reaction mixture confirmed the creation of nanoparticles. UV-Vis spectrophotometeric analysis was used to analyse the produced ZnO nanoparticles. Leaf extract had an absorbance peak at 300 nm, stem extract at 290 nm, and root extract at 288 nm in the reaction mixture.
