“…The results of their studies showed that the yeast was susceptible with a diameter of inhibition of 20 mm at the concentration of 12.5 mg/mL. Jimoh et al [19] showed that the essential oil of S. aromaticum has bacteriostatic activity on C. albicans with an inhibition diameter of up to 44 mm and a MIC of 1 μL/mL. This confirms the antifungal activity of our hydroethanolic and ethanolic extracts.…”

“…According to their study, the pure oil of S. aromaticum inhibited the clinical strains of E. coli with MICs between 2.5 and 3.75 μg/mL and MBCs between 5.0 and 7.5 μg/mL; giving a bacteriostatic activity. Jimoh et al [19] found and Badri [20], by studying the antimicrobial activity of the plant on the reference strains showed that the essential oil of S. aromaticum inhibits the growth of S. typhi ATCC 6539 with a diameter of 15 mm at the concentration 25 mg/mL. This highlights the antibacterial activity of S. aromaticum on Salmonella strains.…”

“…They showed that the pure oil of S. aromaticum inhibits P. aeruginosa with MICs and MBCs ranging from 0.3125 -0.625 μg/mL and 0.625 -0.9375 μg/mL respectively and giving the bacteriostatic activity of the oil. Jimoh et al [19] also reported the bacteriostatic activity of the essential oil of the plant which inhibits the growth of P. aeruginosa with a diameter of 21 mm and a MIC of 9 μL/mL. The literature review also showed that the reference strain, P. aeruginosa ATCC 27853 was sensitive to the essential oil of S. aromaticum with a zone of growth inhibition equal to 16 mm in diameter at the concentration of 50 mg/mL [20], thus attesting the antibacterial activity of the plant on the P. aeruginosa The yeasts showed resistance to the aqueous extract.…”

“…Phytochemical compounds (alkaloids, tannins, flavonoids, anthocyanins, saponosides, terpenes, steroids, coumarins, reducing compounds) found in the fruits of S. aromaticum have been proven by some authors [19]. The antimicrobial activity observed with the aqueous extracts, hydroethanolic and ethanolic would be at the origin of one or more of these phytochemical compounds which would have acted alone or in synergy.…”

Syzygium aromaticum is used in combination with other plants as an alcoholic infusion by traditional practitioners to treat infections. It has been selected for evaluation for its antimicrobial properties to justify its use in traditional pharmacopoeia. The fruits were used as plant material while the microbial germs consisted of six reference strains: Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, Salmonella typhimurium ATCC 14028, Pseudomonas aeruginosa ATCC 27853, Shigella flexneri ATCC 12022, Candida albicans ATCC 35659 and their clinical counterparts. The extracts were obtained by aqueous decoction, hydroethanolic and ethanolic macerations. The phytochemical screening was performed by chemical staining tests. The antibiotic susceptibility test was performed using the well diffusion method and the MIC and MBC or MFC were determined using the 96-well microplate dilution method. The results showed that 66.67% of the strains tested were sensitive to the aqueous extract with inhibition diameters ranging from 15 to 21 mm and MIC and MCB or MFC between 0.0976-0.3906 mg/mL and 0.1953-07812 mg/mL respectively, thus determining bacteriostatic activity. 100% of the germs tested were sensitive to hydroethanolic and ethanolic extracts. The inhibition diameters range from 12-28 mm for hydroethanolic extract with MIC and MBC or MFC ranging from 0.0488-0.3906 mm and 0.0488-0.7812 mm respectively. The ethanolic extract gave inhibition diameters of 12-26 mm; MIC and MBC or MFC ranging from 0.

“…These compounds have been previously reported in the buds of the same plant by other authors. Jimoh et al (2017) showed that the essential oil of Syzygium aromaticum contains 75.10% of Eugenol and 13.57% of Eugenol acetate. However (E)-Caryophyllene was absent in their essence while beta-Caryophyllene was present (5.2%).…”

The objective of this study was to evaluate the chemical composition and antioxidant activity of Monodora myristica and Syzygium aromaticum essential oils. The oils were extracted by hydrodistillation and their chemical composition determined by Gas-chromatography coupled to a mass spectrometer detector. The antioxidant activity of the oils was evaluated through the following tests: the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity; the ferric reducing antioxidant power, the metal chelation and finally the hydroxyl radical scavenging activity. Results showed that alpha-phellandrene (52.2%) and (p)-cymene (13.1%) were the most represented compounds in the essence of Monodora myristica while Eugenol (59.5%) and (E)-Caryophyllene (23%) were the most abundant molecules in that of Syzygium aromaticum. The evaluation of the antioxidant activity showed that the oil of Syzygium aromaticum has good antioxidant activity compared to that of Monodora myristica. Practical Applications The essential oils of Monodora myristica and Syzygium aromaticum can be used in the formulation of medicines that can help to fight against the damages and diseases caused by oxidative stress. They can also be used as food additives such as flavouring agents, natural preservative or antioxidants in foods.
