“…This is an indicator that employing bio-manufactured NPs to fight microbial diseases may be preferable to using a medical antibiotic, which is so overused and abused nowadays that most bacteria types had developed resistance against it 44 . The results of NPs in this study are in line with those obtained by Bansal 45 that was conducted in India and reported the antimicrobial effects of clove Ag NPs suspensions against Bacillus cereus (MTCC 1272), Salmonella typhi (MTCC 734), Pseudomonas aeruginosa (MTCC PAO1) and Escherichia coli (MTCC 9537). In contrast with our results, they found that clove extract has substantial inhibitory effects on the examined pathogens at various doses.…”

This study is aimed to Green-synthesize and characterize Al NPs from Clove (Syzygium aromaticumL.) buds plant extract and to investigate their effect on isolated and characterized Salmonella enterica growth. S. aromaticum buds aqueous extract was prepared from local market clove, then mixed with Aluminum nitrate Al(NO3)3. 9 H2O, 99.9% in ¼ ratio for green-synthesizing of Al NPs. Color change was a primary confirmation of Al NPs biosynthesis. The biosynthesized nanoparticles were identified and characterized by AFM, SEM, EDX and UV–Visible spectrophotometer. AFM data recorded 122nm particles size and the surface roughness RMs) of the pure S. aromaticum buds aqueous extract recorded 17.5nm particles size, while the results of Al NPs in the tested sample recorded 21nm particles size with surface roughness RMs about 2.35nm. SEM images revealed the presence of Al NPs with diameters ranged from 33.5-70.4nm with regular spiracles shape particles in the prepared biosynthesized nanoparticle sample. The EDX spectrum analysis showed that the Aluminium weight ratio was 1.75, while it was 50.498 in the Al NPs sample prepared from aqueous extract. UV-Visible spectroscopy data revealed that biosynthesized Al NPs were absorbed at 213nm while Aluminum nitrate was absorbed at 258nm. These results indicate the formation of Al NPs. The antibacterial activity showed that Al NPs exhibited having high antibacterial activity on Salmonella spp. isolates compared to the effect of the control agent (imipenem) in this experiment. We conclude that biosynthesized Al NPs from clove aqueous extract can be exploited as natural antibacterial compounds to inhibit the growth of Salmonella.

“…Till now much research work has been published on green synthesis of nanoparticles using plant extracts. Biosynthesis of silver nanoparticles of S. aromaticum (clove) has been reported as, significant antimicrobial and cytotoxic activity [15,26]. In this study, the aqueous extract of S. aromaticum (Clove), C. tamala (Bay leaf), C. cassia (Cinnamon bark) were tested for synthesis of AgNPs.…”

Syzygium aromaticum (Clove), Cinnamonum tamala (Bay leaf), Cinnamonum cassia (Cinnamon bark) are well known plants in India. All three plants are a rich source of secondary metabolites that find use as antimicrobial agent, in pharmaceutical industry, cosmetics, food and agriculture industry. In regards of antimicrobial activity, green silver nanoparticles were synthesised by using these plants aqueous extract (25%w/v). For silver nanoparticle synthesis different concentration of plant extract were mixed with AgNO3 solution and exposed to sunlight and estimated by the UV-Visible spectrophotometer. Powdered silver nanoparticles (AgNPs) were dissolved in autoclaved distilled water at different concentration (20mg/ml, 10mg/ml, 5mg/ml, and 2.5mg/ml) and performed antimicrobial activity through agar well diffusion method. Silver nanoparticles of all three plants were showed antimicrobial activity against human bacterial pathogen Escherichia coli and Bacillus subtilis. The inhibition zone increased with increasing concentration of all three plants (S. aromaticum, C. tamala and C. cassia) AgNPs, so maximum inhibition zone was observed at 20mg/ml for both pathogens. At higher concentration, the inhibition zone of E. coli were 2.25 ±0.05, 1.7 ±0.1 and 1.85 ±0.05 cm in presence of S. aromaticum, C. tamala and C. cassia AgNPs respectively. Although, The presence of phytochemical terpenoids, tannin and glycosides are was confirmed by the chemical reagent test. In modern era, the nanoparticle based medicine is explored in pharmaceutical and medical science. Therefore this green synthesis of silver nanoparticle can be explored in pharmaceutical science.
