“…FTIR spectra (Figure 2) of the EO and EM, were recorded in the range of 400-4,000 cm −1 using a Thermo Scientific Nicolet iS10 Spectrometer. Analysis of the samples EO and EM revealed the presence of the characteristic carbonyl stretching absorptions as one of the strongest bands (1,730-1,690 cm −1 ) corresponding to typical trans-cinnamaldehyde (Boughendjioua et al, 2017) which is also in agreement with the GC/MS study where this compound was determined to be the most abundant. However, unlike EO, the spectrum of EM exhibited a broad absorption band at 3407.96 cm −1 which can be assigned to -OH or -NH vibrations.…”

Cinnamon essential oil and its emulsion as efficient antibiofilm agents to combat Acinetobacter baumannii

et al. 2022

Acinetobacter baumannii is an emerging nosocomial pathogen resistant to a wide spectrum of antibiotics, with great potential to form a biofilm, which further aggravates treatment of infections caused by it. Therefore, searching for new potent agents that are efficient against A. baumannii seems to be a necessity. One of them, which has already been proven to possess a wide spectrum of biological activities, including antimicrobial effect, is cinnamon essential oil. Still, further increase of antibacterial efficacy and improvement of bioavailability of cinnamon oil is possible by emulsification process. The aim of this study was comparative analysis of cinnamon essential oil and its emulsion against biofilm forming A. baumannii clinical isolates. Furthermore, the investigation of toxicological aspects of possible applications of essential oil and emulsion was done as well. Gas chromatography–mass spectrometry of essential oil indicated trans-cinnamaldehyde as the most abundant component. The cinnamon emulsion was synthesized from cinnamon essential oil by combining modified low- and high- energy methods. Synthesized emulsion was characterized with Fourier-transform infrared spectroscopy and photon correlation spectroscopy. Both substances exhibited significant antibacterial (minimal inhibitory concentrations in the range 0.125–0.5 mg/ml) and antibiofilm effects (inhibitions of formation and reduction of pre-formed biofilm were 47–81 and 30–62%, respectively). Compared to essential oil, the efficacy of emulsion was even stronger considering the small share of pure oil (20%) in the emulsion. The result of biofilm eradication assay was confirmed by scanning electron microscopy. Even though the cytotoxicity was high especially for the emulsion, genotoxicity was not determined. In conclusion, strong antibacterial/antibiofilm effect against A. baumannii of the cinnamon essential oil and the fact that emulsification even potentiated the activity, seems to be of great significance. Observed cytotoxicity implicated that further analysis is needed in order to clearly determine active principles being responsible for obtained antibacterial/antibiofilm and cytotoxic properties.

“…FTIR analysis based on molecular vibrations of band spectra is presented in Figure 4 . The purity of the cinnamon oil from the prepared extract was confirmed with the theoretical frequency of the band (Boughendjioua et al., 2017 ) which showed the characteristic absorption peaks of the functional groups in chemical composition with aldehyde C=O stretching at 1743 and 1681 cm −1 and the strongest IR absorptions of carbonyl stretching at 1626 cm −1 . These peaks corresponded to high levels of cinnamaldehyde and aldehydes of the sample.…”

Nanophyto-gel against multi-drug resistant Pseudomonas aeruginosa burn wound infection

2021

Burn wound is usually associated by antibiotic-resistant Pseudomonas aeruginosa infection that worsens and complicates its management. An effective approach is to use natural antibiotics such as cinnamon oil as a powerful alternative. This study aims to investigate topical nanostructured lipid carrier (NLC) gel loaded cinnamon oil for Pseudomonas aeruginosa wound infection. A 2 4 full factorial design was performed to optimize the formulation with particle size 108.48 ± 6.35 nm, zeta potential −37.36 ± 4.01 mV, and EE% 95.39 ± 0.82%. FTIR analysis revealed no excipient interaction. Poloxamer 407 in a concentration 20% w/w NLC gel was prepared for topical application. Drug release exhibited an initial burst release in the first five hours, followed by a slow, sustained release of up to five days. NLC-cinnamon gel has a significant ability to control the drug release with the lowest minimum inhibitory concentration again P. aeruginosa compared to other formulations ( p < .05). In vivo study also showed NLC-cinnamon gel effectively healed the infected burned wound after a six-day treatment course with better antibacterial efficacy in burned animal models. Histological examination ensured the tolerability of NLC-cinnamon gel. The results suggest that nanoparticle-based cinnamon oil gel is a promising natural product against antibiotic-resistant strains of P. aeruginosa in wound infection.

“…In the FTIR spectra of CO, strong peaks appear at about 1670 cm −1 (C=O and C=C stretching) and 1120 cm −1 (C-O stretching). The presence of the phenyl group is confirmed by the peaks at 1600 cm −1 , 1580 cm −1 , and 1450 cm −1 , which correspond to frame vibrations of the benzene rings, and the strong peaks at 740 cm −1 and 690 cm −1 , which correspond to bending vibrations of =CH on the aromatic rings [ 55 ].…”

Modification of Poly(vinyl chloride) with Bio-Based Cassia Oil to Improve Thermo-Mechanical and Antimicrobial Properties

The purpose of this study was to modify plasticised PVC to obtain a material with antimicrobial properties and selected mechanical properties. Natural cassia oil (CO) was used to modify plasticised PVC materials. The modified material was produced by extrusion. The introduced modifier had a maximum concentration of 20 phr. Rheological and mechanical properties were evaluated, and the glass transition temperature was determined. The antioxidant and antimicrobial activity of the agar diffusion method was investigated by analysing the growth inhibition zones against Enterococcus faecalis and Listeria monocytogenes. A favourable effect of the cassia oil content on the increase in antioxidant activity of the developed polymeric materials was found with an increase in the modifier content and the duration of action (30 days). The largest growth restriction zones were observed for L. monocytogenes, i.e., they showed the highest sensitivity to the modified material. The simultaneous decrease in modulus of elasticity, increase in elongation at break, and decrease in Tg indicate that the modifier has a plasticising effect on PVC. The developed material may find application as an active and/or functional material, especially as an emitter of antimicrobial agents, in the packaging used to store minimally processed food.
