Synthesis of Zinc Oxide Nanoparticles Using Leaf Extract of Lippia adoensis (Koseret) and Evaluation of Its Antibacterial Activity

Abstract: The synthesis of metal oxide nanoparticles with the use of medicinal plant extract is a promising alternative to the conventional chemical method. This work aimed to synthesize zinc oxide nanoparticles using a green approach from indigenous “Koseret” Lippia adoensis leaf extract which is an endemic medicinal plant and cultivated in home gardens of different regions of Ethiopia. The biosynthesized zinc oxide nanoparticles were characterized using thermogravimetric analysis, X-ray diffraction, scanning electron … Show more

“…In this regard, it has been found that all the typical peaks that were associated with ZnOx NPs are in consistent with the findings of earlier reported studies [24,58,59]. The average crystalline size is 37 nm, which is very close to the results of existing reports [60,61].…”

“…Natural phytochemicals act as capping agents for the preparation of stable NPs [18]. A variety of plants have been reported for the green synthesis of ZnOx NPs such as Moringa oleifera, Cassia fistula, Hibiscus subdariffa, Citrus aurantifolia, Aloe barbadensis, Laurus nobilis, Ocimum basilicum, Lippia adoensis and Lycopersicon esculentum [19][20][21][22][23][24][25][26].…”

“…Walnut aqueous leaf extract was utilized for the bio-synthesis of ZnO nanoparticles with a size range of 15 to 40 nm and evaluated against E. coli (ZOI = 7 to 9 mm) and S. aureus (Gram-positive bacterial stain) [79]. Demissie, Meron Girma, et al reported Lippia adoensis aqueous leaf extract inspired preparation of ZnO nanoparticles and investigated against Staphylococcus aureus (ZOI = 6-14 mm), Enterococcus faecalis (ZOI = 6-10 mm), Escherichia coli (ZOI = 6-12 mm), and Klebsiella pneumoniae (ZOI = 6-12 mm) [80]. Cayratia pedata-based ZnO nanoparticles were also synthesized by Jayachandran et al The mechanism of Cayratia pedata-based nanoparticles' synthesis is shown in Figure 2 [81].…”
