This study examines the chemical constituents, antioxidant potential, antibacterial mechanism, and antiproliferative activity of Cinnamomum zeylanicum bark essential oil. The compositions of the oil were analyzed by GC-MS, and the major constituents were found to be (E)-cinnamaldehyde (71.50%), linalool (7.00%), β-caryophyllene (6.40%), eucalyptol (5.40%), and eugenol (4.60%). C. zeylanicum essential oil contained remarkable levels of phenolic and bioactive compounds with outstanding ability to scavenge free radicals and inhibit β-carotene oxidation. The growth of pathogenic and spoilage bacteria, especially Gram-positive ones (i.e. Listeria innocua, Staphylococcus aureus, and Bacillus cereus), was highly inhibited by the oil, compared to the Gram-negative pairs (i.e. Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhi). The cells of L. innocua and E. coli (as the most sensitive and resistant strains to the oil, respectively) treated with C. zeylanicum essential oil were observed by scanning electron microscopy to unravel structural changes. It was observed that the essential oil quickly exerted its antibacterial activity through disrupting cell envelope and facilitating the leakage of intracellular compounds. The essential oil had also a dose-dependent antiproliferative effect on adipose-derived mesenchymal stem cells (AT-MSCs), and the cell proliferation could be induced by low concentrations of the oil. The present study indicated that C. zeylanicum essential oil with remarkable antioxidant and antimicrobial properties could be applied to develop novel natural preservatives for food and medicinal purposes.

Chemical constituents of the essential oil from the leaves of Minthostachys mollis (Kunth) Griseb Vaught var. mollis collected in January 2008 at Tuñame, Trujillo State, Venezuela, were separated and identified by GCMS analysis. The essential oil was obtained by hydrodistillation and thirteen components (98.5% of the sample) were identified by comparison with the Wiley GCMS library data base. The two major components were pulegone (55.2%) and trans-menthone (31.5%). The essential oil showed a significant inhibitory effect against Gram-positive and Gram-negative bacteria, especially Bacillus subtilis and Salmonella typhi (4 μg/mL).

Bactericidal Properties

Plants produce compounds with antimicrobial properties that can be used to control diseases of horticultural products, for this reason, the aim of this study was to enlarge the knowledge on the effect of essential oils as an alternative for control for bacterial canker Clavibacter michiganensis subsp. michiganensis (Smith) (Cmm). Essential oil of Lippia palmeri was obtained by hydridestillation from plants collected in Sonora, Mexico. Essential oils of Origanum vulgare, Thymus vulgaris and Cinnamomum zeylanicum were obtained from commercial stores in Hermosillo, Sonora, Mexico. To evaluate the effect of the essential oils on the bacterium Cmm, direct applications in two concentrations (1:1 and 1:5 (v/v)) on tomato plants foliage were carried out. Then, plants were inoculated with 1x10-7 CFU/mL of the bacterium and observed for 12 days. The evaluated parameters were incidence and severity. The essential oils and chemical compounds of Origanum vulgare and Thymus vulgaris had effect against Clavibacter michiganensis subsp. michiganensis up to 9 days after application in a 1:1 (v/v) concentration and up to 12 days after application with the 1:5 (v/v) concentration. The essential oil of Lippia palmeri only had effect until six days after the application with both concentrations; that is to say, only these three types of essential oils had bactericidal properties, since with the essential oil of Cinnamomum zeylanicum the inhibition of Cmm was very limited, both in incidence as in severity.

Postharvest Management

Prolonging crops’ shelf-life while retaining their high quality is a major issue related to postharvest management. During storage, fruits and vegetables are exposed to microbial attacks, which may cause spoilage. Crop deterioration causes the loss of physical properties and drops in quality and nutritional value. Hence, new techniques to improve the resistance of food products are being explored. One promising technique is fumigation. Essential oils and their constituents, due to their antimicrobial properties, are likely to be used as fumigants, as they are highly volatile, effective in low concentrations, biodegradable, and safe. Papers indicate that some of them can improve their quality by increasing the content of antioxidants. This comprehensive review aims to present the current state of knowledge about the influence of essential oil fumigation on crop quality. It covers antioxidant capacity, the content of some bioactive compounds, physicochemical properties, decay properties, and sensory attributes of fruits and vegetables treated with essential oil vapors. The review indicates that this technique might be an interesting field for further exploration due to the promising results presented in the studies. Moreover, the review presents major objectives for current studies and indicates a lack of recent papers in this field.

Normal oil and Essential oil from fresh leaves of Eucalyptus torelliana (F. Muell) were extracted using solvent (Soxhlet) and steam distillation extraction methods respectively. The leaves were screened for the presence of secondary metabolites and the extracted oils for their antimicrobial potentials. The phytochemical screening revealed the presence of Phytates (27.81 mg/g) Phytic acids (7.833mg/g) Oxalates (3.061mg/g) Tannins (2.457mg/g) Phenols (30.00%) Flavonoids (2.948%) Saponins (3.166%) and Alkaloids (2.84%). In addition to this the leaves were found to contain anthraquinone. The two oils extracted from the leaves of Eucalyptus torelliana were studied for their antimicrobial activity against the following isolated microorganisms: Xanthomonas axonopodis, Shigella dysenterine, Pseudomonas solanecearium, Streptococcus faecales, Staphylococcus aureus, Salmonella enterica, Erwinia carotovora, Salmonella typhi. The oils were found to inhibit all the microorganism isolates. The zone of inhibition exhibited by the extracts on the tested microorganism was between 22-6mm. The oil extracts compared favourably with Ampiclox used as a standard control.  The results obtained from this study reveals that the oils extracted from Eucalyptus torelliana has antibacterial activities against enteric pathogens and the oil may be potential source of new antimicrobials against enteric organisms.Keywords- Enteric microorganisms, essential oil, Eucalyptus torelliana, secondary metabolites, solvent extraction

ABSTRACT Objective The aim of this article was (i) to define the chemical constituents of Cinnamomum zeylanicum essential oil (CEO), (ii) to compare the antimicrobial activity of CEO with triple antibiotic paste (TAP) and calcium hydroxide [Ca(OH)2] on planktonic and biofilm Enterococcus faecalis; and (iii) to compare the cytotoxicity of these medicaments on L929 fibroblasts. Materials and methods Gas chromatography-mass spectrometry was used to define the constituents of CEO. Zone of inhibition, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and time-kill tests were performed. Further, 108 human teeth were infected with E. faecalis and treated with the medicaments for 1, 7, and 14 days. Cytotoxicity was assessed by exposing L929 fibroblasts to the medicaments. Results Cinnamaldehyde was the main component of CEO. Triple antibiotic paste had the greatest zone of inhibition and the smallest MIC and MBC. Triple antibiotic paste and CEO eradicated planktonic E. faecalis after 4 and 24 hours, while Ca(OH)2 failed to achieve 100% killing after 24 hours. Cinnamomum zeylanicum essential oil and TAP eradicated biofilm E. faecalis after 7 and 14 days, but Ca(OH)2 could not eliminate E. faecalis after 14 days. Cinnamomum zeylanicum essential oil was the most biocompatible medicament. Conclusion Cinnamomum zeylanicum essential oil is an efficient antibacterial agent against planktonic and biofilm E. faecalis and it was cytocompatible to L929 fibroblasts. Therefore, CEO has the potential to be used as an antimicrobial agent in root canal treatment.

Radical Scavenging Properties

Croton ferrugineus Kunth is an endemic species of Ecuador used in traditional medicine both for wound healing and as an antiseptic. In this study, fresh Croton ferrugineus leaves were collected and subjected to hydrodistillation for extraction of the essential oil. The chemical composition of the essential oil was determined by gas chromatography equipped with a flame ionization detector and gas chromatography coupled to a mass spectrometer using a non-polar and a polar chromatographic column. The antibacterial activity was assayed against three Gram-positive bacteria, one Gram-negative bacterium and one dermatophyte fungus. The radical scavenging properties of the essential oil was evaluated by means of DPPH and ABTS assays. The chemical analysis allowed us to identify thirty-five compounds representing more than 99.95% of the total composition. Aliphatic sesquiterpene hydrocarbon trans-caryophyllene was the main constituent with 20.47 ± 1.25%. Other main compounds were myrcene (11.47 ± 1.56%), β-phellandrene (10.55 ± 0.02%), germacrene D (7.60 ± 0.60%), and α-humulene (5.49 ± 0.38%). The essential oil from Croton ferrugineus presented moderate activity against Candida albicans (ATCC 10231) with an MIC of 1000 μg/mL, a scavenging capacity SC50 of 901 ± 20 µg/mL with the ABTS method, and very strong antiglucosidase activity with an IC50 of 146 ± 20 µg/mL.
