“…The Physicochemical properties of ten essential oils were characterized by color, specific gravity, and refractive index. The color of ten essential oils was determined visually (Kartiko et al 2021). The specific gravity was determined using a pycnometer (Boukhatem et al 2014); and the refractive index was determined using a hand refractometer (Kartiko et al 2021).…”

Abstract. Aryani F, Kusuma IW, Meliana Y, Sari NM, Kuspradini H. 2023. Potential antibacterial and antioxidant activities of ten essential oils from East Kalimantan, Indonesia. Biodiversitas 24: 665-672. This study aimed to evaluate ten aromatic essential oils' antibacterial and antioxidant activity. Ten aromatic herbs were distilled using the water and steam distillation method. The essential oils obtained was tested for its physical properties, color, refractive index, and specific gravity. The refractive index was measured using a refractometer. On the other hand, specific gravity was measured using a pycnometer. Antioxidant activity testing using the free radical DPPH (2,2-diphenyl-1-picrylhydrazyl) and ascorbic acid was used as the control. Antibacterial activity testing using the agar diffusion method and pathogenic bacteria, namely Salmonella typhi, Escherichia coli, Propionibacterium acnes, and Staphylococcus aureus. Chloramphenicol was used as a positive control and acetone as a negative control. The results obtained essential oils with a slightly yellowish to brownish-yellow color. The highest refractive index and specific gravities were Syzygium aromaticum oil, and the smallest was Litsea elliptica and Eucalyptus pellita oils. The results of the antioxidant activity test carried out at a concentration of 500 µg/mL range from 4.82 % to 85.06 % inhibition and showed that the highest inhibition was Cymbopogon citratus and Syzygium aromaticum by 55.76 % and 85.06%, respectively. Antibacterial activity of ten essential oils showed a varied inhibition zone (0-60 mm) against S. typhi, E. coli, P. acnes, and S. aureus. The oil from Cymbopogon citratus and Citrus hystrix had the highest activity against S. typhi (60 and 21.67 mm, respectively), E. coli (60 and 20.33 mm, respectively), P. acnes (60 and 31.11 mm, respectively) and S. aureus (60 mm and 17.89 mm, respectively). The research results showed that the essential oils in this study had the potency for development as a natural antibacterial and antioxidants agents.

“…Eucalyptus is widely used in the pulp and paper industry, but its seeds and leaves also have the potential to produce essential oils. Being secondary plant metabolites, EOs have an important role in decreasing bacterial virulence and also weaken the mechanisms of bacterial invasion (Kartiko et al, 2021;Kouki et al, 2022).…”

The intensive use of antibiotics in aquaculture has resulted in increased resistance among fish pathogens, and this situation has led researchers to investigate the antibacterial properties of natural resources. The present study focused on an essential oil isolated from the leaves of Eucalyptus camaldulensis as a potential antibacterial that could be used against Aeromonas caviae. Eighteen compounds were identified in the essential oil, representing 86.68 % of the total oil. The components were found to be p-cymene (20.09%), β-phellandrene (18.61%), α-phellandrene (7.50%), α-terpineol (6.02%), terpinen-4-ol (5.50%), Crypton (5.36%), spathulenol (4.26%), linalool (3.56%), 1,8-cineole (2.77%), farnesol (2.31%) Cumin aldehyde (2.13%), limonen (2.12%), α-thujene (1.94%), fellendral (1.13%), γ-terpinene (1.10%), sabinene (0.97%), α-pinene (0.68%) and α -terpinen (0.63%). The antibacterial efficiency of essential oils against Aeromonas caviae was determined using Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values, ranging from 200 µg/ml to 400 µg/ml respectively. Our findings revealed the potential of essential oils isolated from Eucalyptus (Eucalyptus camaldulensis) as a natural antibacterial agent that could efficiently contribute to the control of Aeromonas caviae infection in fish.
