“…To our knowledge, this is the first description of ajowan essential oil activity against the tested MRSA strains, LMG 15975 and 16217, although previous literature already mentioned an antibacterial activity against E. coli LMG 8223 [ 27 , 28 ], P. aeruginosa LMG 6395 [ 28 , 29 , 30 ] and MSSA LMG 8064 [ 31 ], as observed in the present study. For the Chinese cinnamon, who is cytotoxic in both tested cell lines, our results presented a better MIC than the one described by Kaskatepe et al (2016) [ 32 ] against the same strain of P. aeruginosa LMG 6395 and the one described against E. coli LMG 8223 [ 33 , 34 ]. As mentioned before, oregano was active against all the tested Gram-negative strains, including P. aeruginosa , which is one of the ESKAPE pathogens that need to be eradicated the most [ 35 ].…”

Antibacterial and Cytotoxic Activities of Ten Commercially Available Essential Oils

et al. 2020

There is a huge concern in the medical field concerning the emergence of bacterial resistance to antibiotics. Essential oils are a source of antibacterial compounds that can overcome this problem. Ten essential oils that are commercially available were investigated in the present study: ajowan, basil, German chamomile, Chinese cinnamon, coriander, clove, lemongrass, Spanish lavender, oregano and palmarosa. Their direct, synergistic and indirect antibacterial activities were evaluated against different human pathogenic Gram-positive and Gram-negative strains. To evaluate their possible use in clinics, the cytotoxicity of these essential oils was also tested on keratinocyte and epithelial cell lines. Except for the Chinese cinnamon, coriander and lemongrass, all other essential oils presented no cytotoxicity at 32 and 16 μg/mL. The highest indirect antibacterial activities were observed with the palmarosa and Spanish lavender in association with penicillin V. These two associations presented a 64-fold decrease against a resistant strain of Staphylococcus aureus, however, at a cytotoxic concentration. It can also be highlighted that when tested at a non-cytotoxic concentration, the activity of oregano in association with penicillin V presented an eight-fold decrease. These results show the interest to use essential oils in combination with antibiotics to reduce their concentrations inside drugs.

Fennel seeds and their aromatic oil contain ingredients which are biologically active with high nutritional value, as well as their antimicrobial and fungal effects and alleviation of some disease symptoms. The aim of this research was to determine the chemical properties of fennel seeds, their aromatic oil, effect on the growth of microbes and alleviation of respiratory disease symptoms such as cough and sore throat. Drinks of fennel seeds and their aromatic oil were prepared with different ratios and used to treat a group of individuals suffering from cough and compare them with the control group. In addition, biscuits containing different ratios of fennel seeds and their aromatic oil were prepared. The results of this study showed that fennel seeds contained a high percentage of protein, Crude fiber, carbohydrates and minerals. The results also showed that fennel seeds and its aromatic oils contained substances, which had an effect in relieving cough and sore throat. Methanolic extract from fennel seeds had antioxidant and antimicrobial activities. This study also showed that biscuits containing fennel seeds and its aromatic oil could be stored for longer periods than biscuits without fennel seeds and its aromatic oil. No change in sensory properties or microbial growth during storage was observed. Therefore, we can use it as a natural preservative. In addition, biscuits prepared containing the different percentages of fennel seeds and their aromatic oil were accepted by the panelists when they were stored. Its sensory properties were well maintained. The results also showed that drink of fennel seeds and their oil had an effective effect in the treatment of cough.

“…Goñi et al (2009) expressed that the major component of cinnamon essential oils is trans-cinnamaldehyde or cinnamaldehyde [ 63 ]. Todd et al (2013) and Kaskatepe et al (2016) indicated that the major substance of Cinnamon was cinnamaldehyde [ 64 , 65 ]. This difference might be due to the spices of cinnamon bark, the environmental factors, the origin and parts of cinnamon, the analysis method and other factors [ 25 , 26 , 27 , 66 , 67 , 68 ].…”

The chitosan-based coating with antimicrobial agent has been developed recently to control the decay of fruits. However, its fresh keeping and antimicrobial mechanism is still not very clear. The preservation mechanism of chitosan coating with cinnamon oil for fruits storage is investigated in this paper. Results in the atomic force microscopy sensor images show that many micropores exist in the chitosan coating film. The roughness of coating film is affected by the concentration of chitosan. The antifungal activity of cinnamon oil should be mainly due to its main consistent trans-cinnamaldehyde, which is proportional to the trans-cinnamaldehyde concentration and improves with increasing the attachment time of oil. The exosmosis ratios of Penicillium citrinum and Aspergillus flavus could be enhanced by increasing the concentration of cinnamon oil. Morphological observation indicates that, compared to the normal cell, the wizened mycelium of A. flavus is observed around the inhibition zone, and the growth of spores is also inhibited. Moreover, the analysis of gas sensors indicate that the chitosan-oil coating could decrease the level of O2 and increase the level of CO2 in the package of cherry fruits, which also control the fruit decay. These results indicate that its preservation mechanism might be partly due to the micropores structure of coating film as a barrier for gas and a carrier for oil, and partly due to the activity of cinnamon oil on the cell disruption.
