    Opis:
    The present communication reports the biosynthesis of zinc oxide nanoparticles using aqueous extracts of leaves, stem, root, flowers and fruits of Duranta erecta L. This plant gains horticultural and medicinal importance due to its various biological activities. Zinc Nitrate Hexahydrate [Zn (NO3)2•6H2O] solution was used as a precursor to synthesize Zinc oxide nanoparticles. The various plant (leaves, stem, roots, flowers, fruits) extracts played as reducing agents. The leaf extract showed strong absorbance peak at 302 nm, stem and flower peaks were located at 299 nm, roots at 293 nm and fruit extract solution peak observed at 317 nm.

    Opis:
    Zinc oxide nanoparticles (ZnO NPs) were synthesized by the green synthesis methods using aqueous extracts of Couroupita guianensis Aubl. This is an eco-friendly, time conservative and cost effective way of nanoparticle production. The aqueous extracts of leaves, stem, flower petals and bark were used to synthesize the nanoparticles. Zinc Nitrate hexahydrate (Zn (NO3)2•6H2O) was used as a precursor material. The prepared Zinc oxide nanoparticles were characterized using UV-Vis spectrophotometric analysis. The wavelength specific UV-Vis absorption peaks for Zinc oxide nanoparticles were recorded between 290 nm to 302 nm which confirmed the presence of Zinc oxide in nano scale. The reaction mixture with aqueous extract of leaf showed maximum absorbance spectral peak at 302 nm, stem at 294 nm, flower petals at 292 nm and bark at 288 nm. This is the first report to explore the use of Couroupita guianensis for the biogenic production of Zinc oxide nanoparticles to meet the demand of the pharmaceutical, medicinal and environmental industries.

    Opis:
    We report the development of green methods for synthesis of zinc oxide at nano scale. Biological systems are being explored for the synthesis of nanoparticles. The plant Clitoria ternatea contains alkaloids, tannins, glycosides, resins, steroids, saponins, flavonoids, phenols, kaempferol, clitorin, taraxerol, aparajitin, sistosterol, hexacosanal and anthoxanthin. The whole plant is traditionally used to treat leprosy, bronchitis, inflammation, leucoderma and tuberculosis. The present report describes the biosynthesis and characterization of zinc oxide nanoparticles using aqueous extracts of leaves, stem, root, flowers and fruits of Clitoria ternatea. The aqueous reaction mixture of leaf, flower petals and roots showed strong broad UV spectral peak at 296 nm, stem at 293 nm and roots at 311 nm.

    Opis:
    The present study states about the biosynthesis and UV-Visible characterization of Zinc oxide (ZnO) nanoparticles using leaf, stem, roots and inflorescence of the medicinal herb Euphorbia hirta. The aqueous extracts of plant parts were acted as capping and reducing agent while Zinc Nitrate Hexahydrate used as precursor. One milliliter of plant extracts mediated the formation of ZnO nanoparticles in solution which were visually confirmed by the development of yellowish color in the reaction mixtures. The optical properties of the reaction mixtures were analyzed by the UV-Visible double beam spectrophotometer. The leaf reaction mixture showed strong absorption band at 302nm, stem reaction mixture at 299nm, and the root and inflorescence reaction mixtures at 310nm. The results indicate that whole Euphorbia hirta plant can be used for the biosynthesis of Zinc oxide nanoparticles.

    Opis:
    The synthesis of Zinc oxide (ZnO) nanoparticles using plant parts is always an attractive and eco-friendly method. The present study focuses on the production of ZnO nanoparticles from Zinc Nitrate hexahydrate (Zn (NO3)2•6H2O) using the aqueous extracts of a medicinal plant Micrococca mercurialis. The plant is found to be rich in primary and secondary metabolites such as proteins, steroids and alkaloids, which are responsible and enhancing the biogenic synthesis of ZnO nanoparticles. Leaves, stems, roots and fruits of M. mercurialis were used to prepare the aqueous extracts. The characterization and confirmation of synthesized ZnO nanoparticles was performed by UV-Visible spectrophotometer. The reaction mixtures showed significant and sharp UV absorbance peaks at 305 nm, 299 nm, 311 nm and 302 nm corresponding to the aqueous extracts of leaf, stem, root and fruits reacted with zinc nitrate respectively. It has been proved that the medicinal plant M. mercurialis can be used to synthesize ZnO nanoparticles and the biological method of synthesis of ZnO nanoparticles are safe and good alternative to the chemical and physical methods.

    Opis:
    The enormous applications of metal nanoparticles urged to find new biologically hazard free methods for huge synthesis. The green synthesis approaches are acknowledged by many scientists due to its cost effective, simple, eco-friendly and resourceful move. The present investigation deals with the bio-production and characterization of zinc oxide (ZnO) nanoparticles using leaf, stem, flowers and fruit pods of the medicinal plant Moringa oleifera. The synthesis of ZnO nanoparticles from the aqueous extracts were mediated by Zinc Nitate Hexahydrate as precursor. Various parameters like time periods, concentration of plant extracts and different temperatures were influenced the synthesis of ZnO nanoparticles.
