The present study reports the results of gas chromatography-mass spectrometry (GC/MS) analyses of the essential oil from flowering aerial parts of Cotinus coggygria Scoop. (Anacardiaceae), as well as its in vitro antifungal activity against nine plant pathogenic fungi. Moreover, the essential oil was evaluated for its antifungal activity using the agar dilution method, and also MICs (minimum inhibitory concentrations) and MFCs (minimum fungicidal concentrations) were determined. The major compounds identified by GC-MS were limonene (49.2%), (Z)-β-ocimene (13.6%), α-pinene (8.8%) and (E)-β-ocimene (5.9%). The oil showed in vitro antifungal activity against some species of the Fusarium genus, Botrytis cinerea, and Alternaria solani. Our study indicates that the oil of C. coggygria could be used as a control agent for plant pathogenic fungi in natural formulations.

The increase in dermatophytoses and the fact that some patients do not respond well to therapy make it necessary to find new antifungal agents. As part of our ongoing studies on medicinal plants from Iran, we studied antidermatophytic activities of Ferula latisecta essential oil, which had shown considerable antifungal activity in preliminary antimicrobial screening. Antifungal activity was evaluated by determination of MIC values using the agar dilution method on type strains of Candida albicans and dermatophytes. The composition of the oil was characterized by GC and GC/MS analyses. The essential oil was rich in polysulfides (75.2%) and exhibited good activity against Trichophyton rubrum and T. verrucosom for about three weeks, with a MIC value 96 μg/mL. The oil showed antifungal activity, especially against dermatophytes, and the activity is probably related to the sulfur-containing components of the oil. This study has identified that the polysulfides-rich essential oil of Ferula latisecta fruits has activity against a range of human pathogenic dermatophytes, justifying future clinical trials to validate its use as a therapeutic alternative for dermatophytosis.

The in vitro antifungal activity was determined of an ethanolic extract of Vitis vinifera L. tendrils (TVV) against ten plant pathogenic fungi, using the agar dilution method; activity was shown against all tested fungi. Fusarium species were the most sensitive with MIC values ranging from 250 to 300 ppm, while the basidiomycete fungus Rhizoctonia solani was the most resistant, with a MIC value of 500 ppm. Electrospray ionization tandem mass spectrometry (ESI-MSn) was used to obtain qualitative information on the main components of TVV. The high amount of polyphenolic compounds contained in TVV is likely to contribute significantly to its antifungal activity.

Aim: The study was to evaluate the phytogenic chemical compounds and Antifungal Activity of essential oil from roots of Selinum vaginatum C.B. Clarke, growing in the Himalayan region of Jammu & Kashmir. Methodology: The essential oil was analyzed by Gas Chromatography & Gas Chromatography-Mass Spectrometry in relation with their Kavot indices and mass spectra. Results: The oil was found completely dominated by oxygenated sesquiterpenoids (71.9%) which includes 14-hydroxy-δ-cadinene (37.5%), khusinol (20.7%), viridiflorol (8.0%), acorenone -B (4.2%) and 14-oxy-α-muurolene (1.1%) whereas δ-cadinene (8.9%), α-copaene (6.8%), germacrene-A (2.5%), and β-caryophyllene (1.3%) were the major compounds among sesquiterpenoids. Monoterpenoids constituted as the minor portion (3.8%) of essential oil. The oil was found almost free from oxygenated monoterpenoids (0.2%). The roots of S. vaginatum are used in folk lore medicines in Jammu & Kashmir. The oil from the roots showed marked antifungal activity. The oil had shown 100% mycelia growth inhibition against A. tenuis, C. graminicola, R. solani and S. sclerotiorum at a concentration of 500 µg/ml, 2000 µg/mL, 2000 µg/mL and 300 µg/mL respectively. However F. oxysporum was found less susceptible to the root oil of S. vaginatum. The IC50 values showed a range from 57.4 µg/mL–74.7 µg/mL as compared to standard fungicides with IC50 values 32.8 µg/mL–98.6 µg/mL. The spore germination inhibition test revealed the root oil as a potent inhibitor with IC50 values as 201.4 µg/mL, 414.7 µg/mL and 784.7 µg/mL for A. tenuis, C. graminicola and F. oxysporum. Conclusion: Our study showed that14-hydroxy-δ-cadinene (37.5%), khusinol (20.7%), & viridiflorol (8.0%) are the major components in this oil and possessed potent antifungal activity against test fungal strain, respectively.

Background: In Benin Republic, the conservation of fermented fishes for a long time is difficult due to the contamination of fungi, which lead to its rapid degradation. This experiment was conducted to evaluate the effect of Cymbopogon citratus Essential Oil (EO) against Aspergillus species isolated from fermented fish samples. Methods: Gas chromatography-mass spectrometry was used to determinate the chemical composition of the C. citratus EO. The agar dilution method was used to evaluate the antifungal activity of the C. citratus EO against Aspergillus species. Data were analyzed using SPSS, Chicago, IL, USA, version 10.0. Results: The major components of C. citratus EO were geranial (41.3%), neral (33.0%), myrcene (10.4%), and geraniol (6.6%). The dominant Aspergillus fungi isolated from the fermented fish samples were A. ochraceus, A. oryzae, A. fumigatus, and A. parasiticus. C. citratus EO exhibited considerable antifungal activity against the growth of fungi isolated from fermented fish samples. There was no significant difference between minimal inhibitory concentrations and minimal fungicidal concentrations of A. ochraceus and A. parasiticus (p>0.05). Conclusion: The findings of this research clearly indicate that the C. citratus EO may be a practical application in controlling the growth of Aspergillus species in fermented fish.

The aim of this study is to investigate the Thymus vulgaris essential oil (TVEO) as an antifungal agent in aromatherapy and/or as an active ingredient in the prevention or management of topical inflammatory diseases. The chemical composition of TVEO was determined with gas chromatography and revealed the presence of 25 compounds. Carvacrol was found to be the major component (56.8%). Antifungal action of TVEO was determined in vitro by using different methods. By the disc diffusion method, TVEO showed more potent antifungal activity against Candida strains than the positive control. The diameter of inhibition zone (DIZ) varied from 34 to 60 mm for Candida yeasts. Significantly higher antifungal activity was observed in the vapor phase at lower quantities. Candida albicans and C. parapsilosis were the most susceptible strains to the oil vapor with DIZ varying from 35 to 90 mm. The minimum inhibitory concentrations (MIC) of yeast were determined with an agar dilution method and revealed that MIC varied from 0.3 to 0.15 µL/mL for yeast species. The topical anti-inflammatory potential of TVEO was also explored in vivo with the croton oil-induced ear edema assay. TVEO exhibited a potent anti-inflammatory effect at all doses (100, 10 and 2 mg/kg), which were statistically similar (p > 0.05) to the positive control. This activity was also confirmed at the cellular level with histopathology analysis. Our results suggest the potential application of this carvacrol-rich TVEO in the prevention and management of fungal infections and topical inflammation and deserve further investigation for clinical applications. Furthermore, while the mode of action remains mainly undetermined and should be studied.
