Essential oils of Origanum majorana L. (marjoram), Illicium verum Hook. f. (star-anise) and Cinnamomum zeylanicum Blume (cinnamon) were obtained by steam distillation using a modified Clevenger device. The antimicrobial activity of each oil was evaluated against the bacteria Staphylococcus aureus, Escherichia coli and the fungi Aspergillus flavus and Aspergillus parasiticus by observing their growth and/or mycelial inhibition through comparison with the standard dish (without oil). The essential oils were analyzed using a gas chromatograph coupled to a mass spectrometer for identification and coupled to a flame ionization detector for quantification. The major constituents of marjoram, star-anise and cinnamon essential oils were 4-terpineol, trans-anetole and cinnamic aldehyde, respectively. In in vitro tests, essential oils of marjoram and cinnamon promoted an inhibitory effect on the bacteria S. aureus and E. coli, while the essential oil of star-anise presented activity only against E. coli. Marjoram, star-anise and cinnamon oils were effective against the studied fungi, presenting an inhibitory effect. The minimal inhibitory concentration for the mycelial growth of A. parasiticus was 1 and 0.01 µL mL-1 for star-anise and cinnamon oils, respectively. The minimal inhibitory concentration for A. parasiticus was 0.25, 2 and 2 µL mL-1 for cinnamon, star-anise and marjoram oils, respectively.

AbstractBiocompounds are promising tools with the potential to control pathogenic microorganisms. The medicinal plant species Ocotea odorifera, Ocotea puberula and Cinnamodendron dinisii, distributed along Brazilian biomes, are sources of chemical compounds of biological interest. This study aimed to evaluate the antifungal activity of the essential oils of O. odorifera, O. puberula and C. dinisii essential oils upon the mycotoxin producers Alternaria alternata, Aspergillus flavus and Penicillium crustosum. The essential oils where characterized by gas chromatography coupled to mass spectrometer (CG-MS). The majority compounds identified were: safrol (39.23%) and camphor (31.54%) in O. odorifera, Beta-caryophyllene (25.01%) and spathulenol (17.74%) in O. puberula, and bicyclogermacrene (23.19%) and spathulenol (20.21%) in C. dinisii. The Minimal Inhibitory Concentration (MIC) of antifungal activity considered diameters higher than 10 mm after 72 h of incubation at 30 ºC. A. alternata presented higher resistance to O. odorifera and C. dinisii oils. The inhibitory effect of O. odorifera on A. flavus showed stabilization at oils concentrations between 50% and 80%, increasing at 90% and 100% (pure oil) treatments. We observed that the essential oils of O. odorifera and C. dinisii have potential in the control of the analyzed fungi species. The essential oil of O. odorifera presented a better activity in all the assays, which can be related to the presence of safrole and phenylpropenes, compounds with known antifungal activity.

The goal of this study was to compare in vitro and in vivo efficacy of moxifloxacin and liposomal amphotericin B (Amp-B) monotherapies and combination treatment against Candida albicans in an exogenous endophthalmitis model in rabbit eyes. Microplate dilution tests and checkerboard analysis were performed to detect in vitro efficacies. Endophthalmitis was induced by intravitreal injection of C. albicans in 40 rabbit eyes with simultaneous intravitreal drug injection according to prophylactic treatment groups. Group 1 (control group) received 0.1 mL of balanced salt solution, group 2 (moxi group) 100 µg moxifloxacin/0.1 mL, group 3 (Amp-B group) 10 µg liposomal Amp-B/0.1 mL, and group 4 (combi group) both 100 µg moxifloxacin/0.05 mL and 10 µg liposomal Amp-B/0.05 mL intravitreally. Clinical examination, quantitative analysis of microorganisms, and histopathologic examination were performed as in vivo studies. The minimum inhibitory concentration of liposomal Amp-B against C. albicans was found to be 1 µg/mL. Moxifloxacin showed no inhibition of in vitro C. albicans growth. The minimum inhibitory concentration values of liposomal Amp-B for C. albicans were reduced two- to eightfold with increasing concentrations of moxifloxacin in vitro. In vivo, there was no C. albicans growth in the combi group (zero of eight eyes), whereas three eyes (37.5%) showed growth in the Amp-B group. Vitreous inflammation, retinal detachment, focal retinal necrosis, and outer nuclear layer loss were found to be lower in the moxi group compared with the control group. Ganglion cell and inner nuclear layer loss was observed in all eyes (100%) in both the moxi and combi groups, whereas only in 25% (two of eight eyes) in the Amp-B group. Moxifloxacin strongly augments the efficacy of liposomal Amp-B against C. albicans in vitro, although it has no in vitro antifungal activity when used alone. It is interesting that we found a synergistic effect for in vitro tests but failed to demonstrate it in vivo. When 100 µg moxifloxacin/0.1 mL is given intravitreally, it has some toxic effects that are limited to the inner retinal layers.

AbstractThe essential oil of Mosla chinensis Maxim cv. Jiangxiangru is known for its antibacterial ability. This study aimed to investigate the chemical composition of Jiangxiangru essential oil and its inhibitory effect on Staphylococcus aureus biofilm formation. Gas chromatography/mass spectrometry (GC–MS) was used to determine the chemical composition of Jiangxiangru essential oil. Subsequently, the eight major chemical components were quantitatively analyzed using GC– MS, and their minimum inhibitory concentration (MIC) values against S. aureus were tested. Biofilm formation was detected by crystal violet semi-quantitative method and silver staining. Of the 59 peaks detected, 29 were identified by GC–MS. Of these peaks, thymol, carvacrol, p-cymene, γ-terpinene, thymol acetate, α-caryophyllene, 3-carene, and carvacryl acetate were present at a relatively higher concentration. The results of the quantitative test showed that thymol, carvacrol, p-cymene, and γ-terpinene were the major components of the essential oil. Among the eight reference substances, only thymol, carvacrol, and thymol acetate had lower MICs compared with the essential oil. Essential oil, carvacrol, carvacryl acetate, α-caryophyllene, and 3-carene showed the better inhibition of S. aureus biofilm formation. When one fourth of the MIC concentrations were used for these substances (0.0625 mg/mL for essential oil, 0.0305 mg/mL for carvacrol, 1.458 mg/mL for carvacryl acetate, 0.1268 mg/mL for α-caryophyllene, and 2.5975 mg/mL for 3-carene), the inhibition rates were over 80%. However, thymol, γ-terpinene, thymol acetate, and p-cymene showed a relatively poor inhibition of S. aureus biofilm formation. When 1× MIC concentrations of these substances were used, the inhibition rates were less than 50%. In conclusion, Jiangxiangru essential oil and its major components, carvacrol, carvacryl acetate, α-caryophyllene, and 3-carene, strongly inhibited biofilm formation in S. aureus.
