Abstract This study aims to investigate the chemical composition, antioxidant, and antimicrobial activity of two essential oils (EOs) from Algerian propolis. The volatile constituents were analyzed by gas chromatography-mass spectrometry. Fifty components were identified from the oils. The major components were found to be: cedrol (17.0%), β-eudesmol (7.7%), and α-eudesmol (6.7%) in EO of propolis from Oum El Bouaghi (EOPO) whilst α-pinene (56.1%), cis-verbenol (6.0%), and cyclohexene,3-acetoxy-4-(1-hydroxy-1-methylethyl)-1-methyl (4.4%) in EO of propolis from Batna (EOPB). The antioxidant properties of EOPO and EOPB were determined using 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS•+) and cupric reducing antioxidant capacity (CUPRAC assays), respectively. Both EOs had more cupric ion reducing ability than scavenging ABTS•+ radicals. The antimicrobial potential of the two EOs against eight pathogens was assayed by the agar diffusion method and the mode of action was determined by microdilution assay. The results revealed that EOPB was bactericidal for all tested pathogenic bacteria and fungicidal for Candida albicans ATCC 10231, whereas, EOPO showed bacteriostatic effect against Escherichia coli O157:H7 and Pseudomonas aeruginosa ATCC27853 and fungistatic effect against C. albicans ATCC 10231. Thus, the obtained results suggest the important use of propolis EOs as preservative agents.

Fiji is highly populated with plants containing essential oils (EO). The essential oils extracted from the leaves of the selected Fijian leafy plants were screened against two Gram-negative bacteria (Salmonella typhimurium, Pseudomonas aeruginosa) and three Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis and Bacillus subtilis). The agar diffusion method was used to examine the antimicrobial activities of the extracted EO. All the EO tested showed antibacterial properties against one or more strains while none of the EO was active against Pseudomonas aeruginosa. Viburnum lantana (Wayfaring tree), Annona muricata (Soursop), Coleus amboinicus (Spanish thyme) and Cinnamomum zeylancium (Cinnamon) showed good inhibition against both Gram-positive and Gram-negative bacteria and proved as worthy source of antimicrobial agent. These findings will help the Pacific population to use the studied plants leaves as antimicrobial agent.

Antibacterial And Antioxidant Activity

In recent years, a concern has been expressed about the impact of antibiotics and synthetic antioxidants, which are used to inhibit microbial growth and retard fat oxidation in foods. In addition, antibiotic resistance presents a serious menace to human and environmental ecosystems. This has led the food industry to use natural resources such as essential oils in the preparation of foods, this forming their sensory profile and increasing preservation time there. The objective of this work is to determine the chemical composition and evaluate the antibacterial and antioxidant activity of the essential oil of Illicium verum. The yield of essential oil extracted by hydro distillation is about 4.13%. The chemical composition of the essential oil extracted from the dried fruits of Illicium verum was studied by gas chromatography coupled with mass spectrometry (GC and GC/MS). Twenty-eight constituents, representing 99.74% of the essential oil were identified. The major compounds are: trans-anethole (83.46%), D-Limonene (4.56%), Estragole (3.47%) and Linalool (1.07%). Antioxidant activity was determined by the DPPH assay. The essential oils of Illicium verum showed low antioxidant activity with IC50= 286.19 ± 7.4 mg/mL, compared to Ascorbic acid IC50= 0.09 ± 0.01 mg/mL. The antibacterial effect of this essential oil was tested against six microorganisms, of which Staphylococcus aureus is the most sensitive with an MIC of about 1/1000 (v/v), followed by Staphylococcus epidermidis and Enterobacter cloacae with an MIC equal to 1/100 (v/v).
