Background: Some plants that are included in the genus Citrus are one of the plants producing essential oils which is a natural substance that is known to have an antibacterial effect.Objectives: The study aims to determine the ability of essential oils from the leaves of several types of citrus (Citrus) in inhibiting the growth of Escherichia coli.Methods: An experimental study using a complete randomized design consisting of 4 treatments and four replications each. The treatments consisted of distilled water (control), lime leaf essential oil, kaffir lime essential oil and lime leaf essential oil. Microbiology test uses agar diffusion method.Results: Anova test showed that essential oils from some lime can inhibit the growth of Escherichia coli (p = 0.000). Duncan's further test results showed that the average diameter of the inhibition zone formed showed that the average diameter of the largest inhibition zone was formed in the treatment which was given lime orange essential oil (16.55 mm) and was not significantly different (p <0.05) with orange essential oil kaffir (15.40 mm) and lime essential oil (14.97 mm). Based on the Duncan test results showed that there is no difference in the average diameter of inhibitory zones between essential oils of lime, lime and lime, this can be caused because the three lime are classified in the same genus, namely the genus citrus.Conclusion: Essential oils from some lime can inhibit the growth of Escherichia coli. The average diameter of the inhibition zone that formed showed the greatest inhibition formed in the treatment which was given lime essential oil.

This study aims to see the effectiveness  of essential oils of leaves, rhizomes and fraction of wild ginger Ellettariopsis slahmong CK Lim against the pathogenic fungus Sclerotium rolfsii which causes rot disease of the stem base of peanut plants an in vitro.The study consisted of two sub activities: (a) inhibited of colony diameter using Patato Dextrosa Agar (PDA) medium and (b) inhibited of colony biomass using Potato dextrose Broth (PDB) medium, the treatments tested were leaf essential oil and rhizome of wild ginger and fractions A1, B2, C3 and D4, with concentration levels (0, 100, 250 and 500 ppm). Experiments (a) and (b) were arranged in the form of a Completely Randomized Design (CRD) in factorial each with 4 replications. The results showed that the leaf essential oil and rhizome of wild ginger and its fractions had the potential to be used as a vegetable fungicide. The A1 fraction has the best antifungal effectiveness compared to the B2 fraction, leaf oil, rhizomes and other fractions, with the highest inhibition of diameter and biomass of S rolfsii colony the 49.47% and 51.46%. Essential oils of leaves and rhizome oil are not statistically significantly different, but in numerically leaf oil are better than rhizome oil. The C3 fraction showed the lowest colony diameter inhibition and biomass of 34.70% and 36.95%. The best concentration level in inhibition the growth of S rolfsii mushroom is 500 ppm, with inhibition of the diameter and biomass of the colony by 81.74% and 84.25%.

Peacock flower (Caesalpinia pulcherrima L.) leaves contain essential oils which can be used as an ingredient in cosmetics, perfume, aromatherapy, medicine, and supplements. The study was conducted to obtain essential oils from peacock flower leaves and determine the antibacterial activity against gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus) and gram-negative (Escherichia coli and Pseudomonas aeruginosa). Antibacterial activity test was carried out by the agar diffusion method, using paper discs. Measurements were made for the inhibition zone diameter (IZD) that appeared, while the essential oil component was analyzed using GC-MS. The results showed that the peacock flower leaves (C. pulcherrima) had a moderate to strong antibacterial effect at a concentration of 7.5%-20% against gram-positive bacteria (B. subtilis and S. aureus) and gram-negative bacteria (E. coli and P. aeruginosa). Gram-negative E. coli bacteria are relatively more sensitive to peacock flower leaf essential oil compared to other test bacteria. Peacock flower (C. pulcherrima) leaf essential oil is composed of 7 main components namely β-Cubebene 33.87%; Caryophyllene 23.00%; γ-Elemene 13.18%; α-Pinene 10.96%; Cadina-1(10),4-diene 10.20%; Copaene; 7.09%; β-Pinene 1.70%.

The present study was carried out to determine, for the first time, the chemical composition and antibacterial activity of essential oils derived from the aerial parts of three aromatic plants Thymus algeriensis Boiss & Reut, Rosmarinus officinalis L., and Salvia officinalis L. growing under semiarid conditions. The essential oils were chemically analyzed and identified by gas chromatography (GC) and GC/ mass spectrometry (GC/MS) and their antimicrobial activity was individually evaluated against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa using both agar disk diffusion and agar dilution methods. The major constituents of Thymus algeriensis essential oil were identified as camphor (13.62%), 1,8-cineol (6.00%), borneol (5.74%), viridiflorol (4.00%), and linalool (3.93%). For Rosmarinus officinalis essential oil, 48 compounds were characterized, of which the main constituents were camphor (17.09%), Z-β-ocimene (10.88%), isoborneol (9.68%), α-bisabolol (7.89%), and borneol (5.11%). While, Salvia officinalis essential oil was characterized by β-thujone (16.44%), followed by viridiflorol (10.93%), camphor (8.99%), 1,8-cineol (8.11%), trans-caryophyllene (5.85%), and α-humulene (4.69%) as the major components. Notably, results from antibacterial screening indicated that Thymus algeriensis and Salvia officinalis essential oils exhibited a strong inhibitory effect against both Escherichia coli and Staphylococcus aureus compared to Rosmarinus officinalis essential oil. Further, less activity was recorded against Pseudomonas aeruginosa for the three tested essential oils.

Members of the genus Cinnamomum (Lauraceae) have aromatic volatiles in their leaves and bark and some species are commercially important herbs and spices. In this work, the essential oils from five species of Cinnamomum (C. damhaensis, C. longipetiolatum, C. ovatum, C. polyadelphum and C. tonkinense) growing wild in north central Vietnam were obtained by hydrodistillation, analyzed by gas chromatography and screened for antimicrobial and mosquito larvicidal activity. The leaf essential oil of C. tonkinense, rich in β-phellandrene (23.1%) and linalool (32.2%), showed excellent antimicrobial activity (MIC of 32 μg/mL against Enterococcus faecalis and Candida albicans) and larvicidal activity (24 h LC50 of 17.4 μg/mL on Aedes aegypti and 14.1 μg/mL against Culex quinquefasciatus). Cinnamomum polyadelphum leaf essential oil also showed notable antimicrobial activity against Gram-positive bacteria and mosquito larvicidal activity, attributable to relatively high concentrations of neral (11.7%) and geranial (16.6%). Thus, members of the genus Cinnamomum from Vietnam have shown promise as antimicrobial agents and as potential vector control agents for mosquitoes.

Aim of this study was to investigate the antimicrobial properties of herbal plant essential oils (EOs) from selected Iranian plant species such as Ferulago angulata, Zataria multiflora, Cuminum cyminum, and Mentha longifolia against antibiotic-resistant Escherichia coli (E. coli) strains. For this purpose, the Escherichia coli strains, isolated from raw cow’s milk and local dairy products (yogurt, cream, whey, cheese, and confectionery products) collected from different areas of Hamedan province, Iran, were investigated for their resistance to antibiotics (i.e., streptomycin, tetracycline, gentamicin, chloramphenicol, ciprofloxacin, and cefixime). Thus, the E. coli strains were tested for their susceptibility to the above-mentioned essential oils. Regarding antibiotics, the E. coli strains were highly sensitive to ciprofloxacin. In relation to essential oils, the most effective antibacterial activity was observed with Zataria multiflora; also, the bacteria were semi-sensitive to Cuminum cyminum and Mentha longifolia essential oils. All strains were resistant to Ferulago angulata essential oil. According to the results, the essential oil of Zataria multiflora can be considered as a practical and alternative antibacterial strategy to inhibit the growth of multidrug-resistant E. coli of dairy origin.
