Chemical composition and antibacterial activity of essential oils of Cinnamomum cassia and Syzygium aromaticum plants and their nanoparticles against Erwinia amylovora

The present study was carried out to determine, for the first time, the chemical composition and antibacterial activity of essential oils derived from the aerial parts of three aromatic plants Thymus algeriensis Boiss & Reut, Rosmarinus officinalis L., and Salvia officinalis L. growing under semiarid conditions. The essential oils were chemically analyzed and identified by gas chromatography (GC) and GC/ mass spectrometry (GC/MS) and their antimicrobial activity was individually evaluated against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa using both agar disk diffusion and agar dilution methods. The major constituents of Thymus algeriensis essential oil were identified as camphor (13.62%), 1,8-cineol (6.00%), borneol (5.74%), viridiflorol (4.00%), and linalool (3.93%). For Rosmarinus officinalis essential oil, 48 compounds were characterized, of which the main constituents were camphor (17.09%), Z-β-ocimene (10.88%), isoborneol (9.68%), α-bisabolol (7.89%), and borneol (5.11%). While, Salvia officinalis essential oil was characterized by β-thujone (16.44%), followed by viridiflorol (10.93%), camphor (8.99%), 1,8-cineol (8.11%), trans-caryophyllene (5.85%), and α-humulene (4.69%) as the major components. Notably, results from antibacterial screening indicated that Thymus algeriensis and Salvia officinalis essential oils exhibited a strong inhibitory effect against both Escherichia coli and Staphylococcus aureus compared to Rosmarinus officinalis essential oil. Further, less activity was recorded against Pseudomonas aeruginosa for the three tested essential oils.

Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

In this study, clove bud oil, which was cultivated in the Mediterranean region of Turkey, was provided from a private essential oil company in Turkey. Essential oil from clove (Syzygium aromaticum L.) was obtained from steam-distillation method, and its chemical composition was analyzed by GC and GC-MS. The results showed that the essential oils mainly contained about 87.00% eugenol, 8.01% eugenyl acetate and 3.56% β-Caryophyllene. The chemical composition of the Turkish clove bud oil was comparable to those of trees naturally grown in their native regions.

Cellulosic Fibers

We report an analysis of chemical components of essential oils from barks of Ceylon cinnamon and cloves of Syzygium aromaticum and an investigation of their antibacterial activity. The components of oils were determined by using Gas Chromatography/Mass Spectrometry (GC-MS) analysis, and the antimicrobial activity was assessed by the disk diffusion test. The synergic effect of essential oils mixture (cinnamon oil and clove oil) was evaluated. Antimicrobial properties were conferred to cellulosic fibers through microencapsulation using citric acid as a green binding agent. Essential oil mixture was encapsulated by coacervation using chitosan as a wall material and sodium hydroxide as a hardening agent. The diameter of the produced microcapsules varies between 12 and 48 μm. Attachment of the produced microcapsules onto cotton fabrics surface was confirmed by Attenuated Total Reflectance-Fourier Transformed Infrared (ATR-FTIR) spectroscopy, optical microscopy and Scanning Electron Microscopy (SEM) analysis. The results show that microcapsules were successfully attached on cotton fabric surfaces, imparting antibacterial activity without significantly affecting their properties. The finished cotton fabrics exhibited good mechanical properties and wettability.

H Pylori

The susceptibility of Helicobacter pylori to three essential oils (EOs), 12 naturally occurring monoterpene hydrocarbons, oxygenated and phenolic monoterpenes and three reference antibiotics were studied. Classification and comparison of essential oils and monoterpenes on the basis of their chemical composition and antibacterial activity were made by the utilization of principal component analyses (PCA) and agglomerative hierarchical clustering (AHC). The most abundant compound in the Thymus glabrescens Willd. and Thymus pulegioides L. EOs is geraniol (33.8% and 52.5%), while the main constituent in Satureja kitaibelii Wierzb. ex Heuff. EO is limonene (16,1%). The compound that was the most active against H. pylori was carvacrol. EOs of T. glabrescens and S. kitaibelii exhibit higher antibacterial ability in comparison with all monoterpenes, except carvacrol, probably based on the concept of synergistic activity of essential oil components. PCA separated essential oils based on chemical composition and explain 96.5% of the total variance in the first two principal components. Essential oils, phenolic monoterpenes and two antibiotics were classified in the same sub-cluster within AHC analyses. EOs of T. glabrescens and S. kitaibelii can be used to treat infections caused by H. pylori, as a potentially effective, cheap and safe natural products. Further research of antibacterial activity of selected monoterpenes, essential oils and standard antibiotic combinations, as well as clinical study are required.

Objective: The aim of the current study is to determine the chemical composition and evaluate antibacterial activity of Vitex agnus-castus L. (VAC) essential oils against some bacteria causing nosocomial infections in the neonatal and intensive care rooms at the university hospital center of Fez Morocco. Methods: The phytochemical screening of essential oils was determined using gas chromatography (GC) and GC-mass spectrometry analysis. The antibacterial test was evaluated against Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria species (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Proteus mirabilis) using disc diffusion method. Results: Twenty-nine components were identified in the fruits’ oil representing 93.1% of total oil. The major components in the fruits oil are 1,8-cineole (11.6%), α-thujene (9.3%), phyllocladene (8.2%), α-pinene (7.9%), caryophyllene (5.9%), and cubenol (5%). Furthermore, 28 components were identified in the leaf essential oil. The main component was caryophyllene (9.5%), followed by 1,8-cineole (8.7%), manoyl oxide (7.3%), eugenyl acetate (7.1%), phyllocladene (6.8%), and α-pinene (5.2%). Antibacterial activity of both oils showed a strong activity against nosocomial bacteria tested. Conclusion: Essential oils of Moroccan VAC could be exploited as natural drugs for bacteria, especially those who have acquired resistance to conventional antibiotics.
