- Abstract
Cinnamomum cassia (cinnamon cassia) belongs to the Lauracea family, whose commonly used product is cinnamon. Cassia cinnamon is obtained from the trunk of the cinnamon tree, a tree whose dry branches are separated from their reddish brown "barks", which are very fragrant. Cinnamomum cassia essential oil has several pharmacological properties, such as antioxidant, anticancer, antidiabetic, antiinflammatory, antibacterial and antifungal. Due to the emergence of resistance of microorganisms to commonly used antibiotics, it is of great relevance to study the bioactive properties of Cinnamomum cassia essential oil, with a focus on antimicrobial action, which could be a new compound that could help in the prevention of human illnesses. The antibacterial and antifungal activity of Cinnamomum cassia (Cassia cinnamon) essential oil was evaluated against the ATCC strains: Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853 and Klebsiella pneumoniae ATCC 7006 03 and the strains fungal ATCC: Candida albicans ATCC 76615, Candida guilliermondii ATCC 6260 and Candida glabrata ATCC 90030. The antimicrobial activity of Cinnamomum cassia was performed using the modified Agar diffusion method, in a qualitative way. This technique, described by Brcast 2023. And quantitatively by macrodilution in broth. In the disc diffusion technique, Cinnamomum cassia essential oil showed antimicrobial activity against the bacterium Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and Escherichia coli, with halos of 40mm, 33mm, 27mm and 34mm respectively. However, it did not show inhibitory activity against Enterococcus faecalis. As for the antifungal activity using Candida albicans, Candida guilliermondii and Candida glabrata, they presented a halo of 30mm, 35mm and 30mm respectively. In the broth dilution test, no sensitivity activity was observed in any of the dilutions used of the raw essential oil of cinnamon cassia. It is inferred from this study that Cinnamomum cassia essential oil demonstrated better antimicrobial activity in Agar diffusion (qualitative) against the majority of pathogens evaluated. It demonstrated efficacy against Gram-negative microorganisms, specifically Klebsiella pneumoniae, followed by Pseudomonas aeruginosa and Escherichia coli. Among Gram-positive microorganisms, sensitivity was observed in relation to Staphylococcus aureus. In the quantitative test, no sensitivity results were found in any of the strains analyzed. As far as antifungal capacity is concerned, Cinnamomum cassia essential oil has demonstrated remarkable efficacy against strains of Candida albicans, Candida guilliermondii and Candida glabrata.
