Phyto-fabricated ZnO nanoparticles from Canthium dicoccum (L.) for antimicrobial, anti-tuberculosis and antioxidant activity

Novel Green In Situ Synthesis of ZnO Nanoparticles on Cotton Using Pomegranate Peel Extract

“…The decrease of antioxidant activity of cotton samples is due to the consumption of polyphenolic compounds for adsorption on cotton but predominantly for the formation of ZnO-NP, which additionally confirms the formation of ZnO on cotton. Mahendra et al [ 67 ] also found that the antioxidant activity was highest for plant extracts alone, lower for ZnO synthesized using plant extract, and even lower for ZnO produced by chemical synthesis. Moghaddam et al [ 68 ] also presented similar results, where the antioxidant efficacy of green synthesized ZnO was related to the phytochemicals bound to the surface of nanoparticles.…”

Genotoxic and Cytotoxic Properties of Zinc Oxide Nanoparticles Phyto-Fabricated from the Obscure Morning Glory Plant Ipomoea obscura (L.) Ker Gawl

“…The spectrum band at 496.94 cm −1 in ZnO-NPs (Figure 4A) confirmed the formation of the metal oxide bond, while the non-appearance of the peaks around 3350 cm −1 (Figure 5) indicates the particles were moisture-free (Table S2 in Supplementary Materials). It may be noted through the FT-IR spectrum of ZnO-NPs that functional groups present in plant extract had complexed well to form a metal oxide as indicated by the absence of major peaks between 600 and 400 cm −1 [2,5,6]. The results affirm that during the phyto-fabrication of ZnO-NPs, the metabolites in plant extract act as capping/stabilizing agents to form a metal oxide, which is also in agreement with the conclusions of other researchers [6,9,25].…”

“…Nanotechnology is a multidimensional discipline that has the potential to transform all the fields of science. Nanoparticles have gained importance due to their surface area to volume ratio and the behaviors that result from that [1,2]. In light of the environmental and biological risks due to the toxicity of used chemicals in synthetic metal-oxide nanoparticles, biologically synthesized nanoparticles have gained considerable importance as they are considered to be stable, eco-friendly, and also possess biological properties [3][4][5][6].…”

“…They have also shown to possess many biological properties such as antioxidant, antimicrobial, genotoxicity, cytotoxicity, etc., thereby indicating the efficacy toward their application in the field of pharmaceuticals [5,8,9,14,15]. The toxicity of chemically synthesized nanoparticles has paved the way for plant-mediated biosynthesis of nanoparticles due to their stable and eco-friendly nature in addition to their enhanced biological properties compared to chemically synthesized nanoparticles [2,5,8,9].…”

Crotalaria verrucosa Leaf Extract Mediated Synthesis of Zinc Oxide Nanoparticles: Assessment of Antimicrobial and Anticancer Activity

“…The results are mean of three replicates. The hydroxyl groups of the secondary plant metabolite such as phenolic compounds and the flavonoids (such as flavonols, flavones, and condensed tannins) are reported to employ antioxidant activity both in vitro and in vivo, which help in promoting radical scavenging potential [42][43][44].The literature states that diverse group of plant extracts include secondary plant metabolites, phyto-proteins, flavonoids, polyphenolic compounds, alkaloids, polysaccharides, sugar compounds, aromatic amines, and amino acids have properties of both reducing (reduction of metal oxides to 0 valence metal NPs) and stabilizing agents [45][46][47]. C. verrucosa has previously reported for its several positive biological effects including antioxidative, anti-apoptotic, anti-aging, anticancer, and anti-inflammatory impacts, that is due to number of plant-based compounds such as polyphenolic and flavonoids [48].…”
