Damask rose (Rosa damascena Mill.) is an aromatic medicinal plant rich in bioactive compounds with high value in the food, pharmaceutical and cosmetic industries. Knowledge of the factors affecting the quantitative and qualitative properties of the compounds in its essential oil (EO) and the bioactivity of this EO is important in optimizing Damask rose cultivation and production. This research studied, for the first time, the effects of irrigation water and soil chemical and physical characteristics on the EO yield of this important commercial species and on it chemical composition and antimicrobial activity. The results showed the significant effect of crop cultivation site on yield, chemical composition and inhibition zone diameter (IZD) at the 1% significance level. The highest EO yield (~0.0266%), which belonged to the Noushabad site (EON), resulted from the increased soil electrical conductivity (EC) and the higher sand, gypsum and lime contents and irrigation water salinity. Analysis of the chemical composition of the EOs showed that their main compounds at all three crop sites were citronellol, nonadecane, heneicosane and geraniol. The EO obtained from the Yazdel site (EOY) had the highest contents of citronellol and geraniol (~29.05% and ~6.85%) that were directly correlated with soil potassium and phosphorus contents and inversely correlated with soil acidity and EC and its lime, nitrogen, and organic carbon contents. Antimicrobial assays indicated that the EO extracted from the Sefidshahr site (EOS), which had the largest inhibition zone diameter (~14.67 mm) for Aspergillus brasiliensis (IZD~14.67 mm) and the lowest MIC (~31.25 μg/mL) for Staphylococcus aureus and Pseudomonas aeruginosa, exhibited efficacy similar to that of rifampin, probably due to the dominance of the alkanes in it. The EOY and EOS also exhibited the strongest inhibitory and lethal activity against Candida albicans (MIC and MBC <15.63 μg/mL for EOY and MIC and MBC = 62.5 μg/mL for EOS), which were six and four times stronger than those of nystatin, respectively. Therefore, the selected EOs can act as a potentially promising strategy for fighting microbial strains.

Abstract Background Essential oil of Rosa × damascena Herrm. is one of the most valuable and important raw materials for the flavor and fragrance industry. The cultivation of this plant has ancient origins, and Kashan was one of the first mountainous regions of Iran dealing with the cultivation of R. × damascena. In this study, both chemical composition and antimicrobial activity of different rose essential oils obtained from five mountainous areas of Kashan region (Maragh, Qamsar, Sadeh, Javinan, and Kamoo) has been investigated along with the influence of the environmental conditions on these properties. Results Results showed that yield and chemical composition of essential oils obtained from Rosa × damascena were significantly affected by the collection area. In particular, the yield of oils varied from ~0.08 to ~0.132% and citronellol (36.70-9.18%), geraniol (12.82-0.47%), nonadecane (22.73-10.36%), heneicosane (31.7-11.43%), and 1-nonadecene (6.03-3.93%) have been detected as main compounds in all the plants collected, but at different concentrations depending on the collection area. The best fragrance and the highest yield were found in the oil from Kamoo area. Similarly to the chemical composition, the antimicrobial activity of the essential oils was affected by their origin, and essential oil obtained from plants collected from Kamoo area disclosed the highest antibacterial and antifungal efficacy. Its inhibition halos were 17.33±0.58 mm against Aspergillus brasiliensis, 15.67±0.58 mm against Staphylococcus aureus, and 12.33±0. 58 mm against Streptococcus pyogenes. Essential oils of R. damascena were also effective against Gram-negative Pseudomonas aeruginosa and they had a MIC value of 62.50 μg/mL irrespective of the collection area (except the oil from Javinan area). On the contrary, the highest antifungal power against Candida albicans yeast was reached using the essential oil obtained from plants collected in Javinan region (MIC and MBC ~62.50 μg/mL). Conclusions Overall results underline the influence of environmental conditions of the different areas of Kashan region, on the chemical composition of and antimicrobial activity of the essential oils of Rosa × damascena. In addition, results disclosed that Kamoo seemed to be the most suitable area for the competitive cultivation of R. × damascena to the intensive production of aromatic flower oil and natural antimicrobial essential oils.

The study evaluated the antimicrobial activity based on chromatographic analysis of ethanolic extract of Funtumia elastica leaves and stem bark. Funtumia elastica leaf and stem bark samples were air dried, grinded and extracted in ethanol by soxhlet extraction. The defatted ethanol extract was partitioned in dilute sodium hydroxide, hydrochloric acid and chloroform to obtain basic, neutral and acidic metabolites. The phytochemical test on the defatted crude extract of Funtumia elastica leaf and stem bark show the presence of tannins, alkaloids, flavonoids, saponins, terponoids, anthraquinone, phenolics and steroids. The crude extract, basic, neutral and acidic metabolites, and the fractions obtained by thin layer chromatography were screened for their antimicrobial activity at concentration of 100mg/ml against Streptococcus pneumoniae(sp), Staphylococcus aureus(sa), Salmonella typhi(st), Escherichia coli(ec) and Candida albicans(ca). The results show that the crude extract of stem with inhibition zone diameter(mm) of 22, 18, 20, 22 and 20 against (sp), (sa), (st), (ec) and (ca) respectively had better antimicrobial activity than the crude extract of leaf with inhibition zone diameter(mm) of 16,10,16,14 and 12 against (sp), (sa), (st), (ec) and (ca) respectively. Also the TLC fractions exhibited lower antimicrobial activity when compared to that of the basic metabolites. The fractions obtained by thin layer chromatography which showed promising antimicrobial activity were analysed by gas chromatography mass spectroscopy (GC/MS). The GC/MS spectra revealed thirty-nine peaks from which thirty nine compounds were identified. The identified compounds were mainly carboxylic acids and esters. The results of antimicrobial screening show that the crude extracts of the stem bark with inhibition zone diameter (mm) of 22, 18, 20, 22 and 20 were comparable to the standard drugs ciprofloxacin with inhibition zone diameter (mm) of 18, 20, 20, and 15 and gentamycin with inhibition zone diameter (mm) of 10, 20, 15, 12, and 18.

Abstract The antibacterial activity of lime (Citrus aurantifolia) essential oil (LEO) and limonene was tested against seven Gram-negative and nine Gram-positive fish pathogenic bacteria isolated from cultured olive flounder, Paralichthys olivaceus (Temminck & Schlegel) in Korea. Limonene was >99% concentrated and LEO consisted of eleven chemical compounds including 56.22% of limonene. Disk diffusion assay, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) tests were done. LEO and limonene inhibited the growth of both Gram-negative and Gram-positive bacteria. LEO and limonene (MBC/MIC= 2-8) were both bactericidal and bacteriostatic for the strains tested. In every fish pathogenic bacteria, the inhibition zone diameter (IZD) increased in proportion to the oil concentration and the maximum effect was found at 100% (V/V) concentrations of LEO and limonene. The antibiogram pattern indicated that all the bacterial strains, excluding three strains of S. iniae (S186, S530, and S131), showed resistance to one or more antibiotics. The percentage of the relative inhibition zone diameter (RIZD %) exhibited high values at higher concentrations of all the agents. Since antibacterial activities of LEO and limonene were considerably effective against fish pathogenic bacteria, they could be used as alternatives to treat bacterial infections in aquaculture.

As with any essential oil (EO), the content and composition of Rosa × damascena Mill L. (EO) can be changed significantly, depending on the cultivation methods and terroir. The purpose of this research is to determine the chemical composition and biological activities of EO distilled from Damask rose flowers cultivated in Armenia at high elevation. The EO was obtained by hydro-distillation method, the chemical composition was analyzed by gas-chromatography analysis. The EO main compounds were citronellol (38.04%), nonadecane (4.9 %), nerol (7.12%), geraniol (26.32%) and linalool (6.15%). The antioxidant activity of EO was measured by the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), TBARS and metal-chelating activity determination assays. Antimicrobial activity was determined by agar-diffusion method. According to our investigations the minimal inhibitory concentration values against tested gram-positive and gram-negative bacteria were varied between the 2.5 and 20 mg·mL–1. Obtained data revealed high (DPPH) scavenging, metal chelating, lipid peroxidation inhibiting activities of EO. Thus, the results revealed a good potential of R. damascena EO.

Antibacterial activity of cinnamon (Cinnamomum zeylanicum) essential oil (CEO) and cinnamaldehyde was tested against seven Gram negative and nine Gram positive fish pathogenic bacteria isolated from cultured olive flounder (Paralichthys olivaceus) in Korea. Disk diffusion assay, MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) tests were done. Cinnamon and cinnamaldehyde inhibited the growth of both Gram negative and Gram positive bacteria. Cinnamaldehyde showed lower MIC values than CEO which ranged from 0.001 to 0.015% (V/V). CEO (MBC/MIC 2-4) was bactericidal for all tested strains while cinnamaldehyde was bactericidal for all except 6 strains. For all fish pathogenic bacteria, the inhibition zone diameter (IZD) increased in proportion to the oil concentration and the maximum effect was found at 100% (V/V) concentration of CEO and cinnamaldehyde.  The antibiogram pattern indicated that all the bacterial strains excluding three strains of Streptococcus iniae(S186, S530 and S131) showed resistance to one or more antibiotics. Higher percentages of relative inhibition zone diameter (RIZD %) were exhibited at higher concentrations of CEO and cinnamaldehyde. Since antibacterial activities of CEO and cinnamaldehyde were considerably effective against fish pathogenic bacteria, these could be used as alternatives to treat bacterial infections in aquaculture.

AbstractEssential oils are natural products that have great antimicrobial potential value against many fungi and bacteria. Rosa damascena Mill. is one of the most important aromatic species of the Rosaceae family from which essential oil and economically valuable products can be obtained. The present study was designed to investigate the major compositions of the essential oil of this plant in Isfahan region of Iran and to identify its antibacterial and antifungal effects against 11 microorganisms causing human diseases and food spoilage. The essential oil was extracted by using the Clevenger apparatus and was analyzed by gas chromatography-mass spectrometry (GC–MS) technique. Its antimicrobial activity was evaluated by well diffusion, minimum inhibitory concentration (MIC) and minimum bactericide concentration (MBC). The results showed that the most important compounds of the essential oil were nonadecane (24.72%), heneicosane (19.325%), oleic acid (17.63%), and citronellol (12.61%). The results also showed that the highest inhibition zone of rose essential oil was against Aspergillus brasiliensis (15.00 ± 0.00 mm) and had a significant effect on Klebsiella pneumoniae (~ 8.00 mm). Also the rose oil had a significant inhibition and lethal effect against Candida albicans (MIC and MBC ~ 125 μg/mL), which is equivalent to the nystatin antibiotic (~ 125 μg/mL). Therefore, the essential oil of Damask rose can be considered as an alternative natural product for the prevention and treatment of fungal diseases in humans and against food spoilage as well.

In this study, the essential oil of Origanum vulgare was evaluated for putative antibacterial activity against six clinical strains and five reference strains of Aggregatibacter actinomycetemcomitans, in comparison with some antimicrobials. The chemical composition of the essential oil was analyzed, using chromatography (CG) and gas chromatography–mass spectrometry coupled (CG–MS). The major compounds in the oil were Carvacrol (32.36%), α-terpineol (16.70%), p-cymene (16.24%), and Thymol (12.05%). The antimicrobial activity was determined by an agar well diffusion test. A broth microdilution method was used to study the minimal inhibitory concentration (MIC). The minimal bactericidal concentration (MBC) was also determined. The cytotoxicity of the essential oil (IC50) was <125 µg/mL for THP-1 cells, which was high in comparison with different MIC values for the A. actinomycetemcomitans strains. O. vulgare essential oil did not interfere with the neutralizing capacity of Psidium guajava against the A. actinomycetemcomitans leukotoxin. In addition, it was shown that the O. vulgare EO had an antibacterial effect against A. actinomycetemcomitans on a similar level as some tested antimicrobials. In view of these findings, we suggest that O.vulgare EO may be used as an adjuvant for prevention and treatment of periodontal diseases associated to A. actinomycetemcomitans. In addition, it can be used together with the previously tested leukotoxin neutralizing Psidium guajava.
