AbstractPropolis has been used in traditional folk medicine for ages owing to a number of biological effects. Four propolis samples of Czech and one of Slovak origin were extracted using Soxhlet apparatus and analysed by thin-layer chromatography. Raw propolis samples and their extracts were tested by microdilution broth method to determine minimal inhibitory concentration (MIC) in eight strains of human pathogenic fungi. Raw propolis samples showed a lower in vitro antifungal activity than their extracts. In general, the petroleum ether extracts exhibited the highest in vitro antifungal activity (MIC range of 16–64 µg/ml). The content of flavonoids in the samples varied according to region. The highest amount of flavonoids was found in sample A that originated from Broumov (4%). The most susceptible to the propolis extracts were Trichophyton mentagrophytes and Candida albicans. The propolis samples of Czech and Slovak origin and their extracts showed a considerable in vitro antifungal effect which was associated especially with nonpolar petroleum ether and toluene extracts. There was only a partial correlation between flavonoids content and in vitro antifungal activity.

Background: Currently, there is a trend towards using natural and ethnopharmacological species with therapeutic potential. This investigation evaluated the antifungal activity of two species in the Ecuadorian Andes, which are used in treating dermatomycosis: Ambrosia arborescens Mill. (Marco) and Aristeguietia glutinosa Lam. (Matico). Methods: We worked with seven concentrations (100 to 700ppm) of Ambrosia arborescens Mill. extract and ten concentrations (0.5 to 5%) of essential oil (EO) of Aristeguietia glutinosa Lam. on Trichophyton mentagrophytes ATCC 9533, Trichophyton rubrum ATCC 28188, Microsporum canis ATCC 36299 and Candida albicans ATCC 10231. The methodology used was a modified version of the Kirby-Bauer method, using diffusion in agar wells. Results: The Tukey test, after the one-way Anova, determined effective concentrations of EO: 5% for Trichophyton mentagrophytes, 4.5% for Trichophyton rubrum, 5% for Microsporum canis and 2% for Candida albicans. In the extracts, the concentration of 700ppm was used for Trichophyton mentagrophytes, Trichophyton rubrum, and 600ppm for Microsporum canis and Candida albicans. Conclusions: The evaluation of the antifungal activity of the Ambrosia arborescens extract showed inhibition in the studied dermatophytes in each one of the planted concentrations (100 to 700ppm). The evaluation of the antifungal activity of Aristeguietia glutinosa EO showed inhibition in the studied dermatophytes in each of the planted concentrations (0.5 to 5%).

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.

A series of novel 3-aryl-4-hydroxy-2(5H) furanone-acrylate hybrids were designed and synthesized based on the natural butenolides and acrylates scaffolds. The structures of the prepared compounds were characterized by 1H-NMR, 13C-NMR and electrospray ionization mass spectrometry (ESI-MS), and the bioactivity of the target compounds against twelve phytopathogenic fungi was investigated. The preliminary in vitro antifungal activity screening showed that most of the target compounds had moderate inhibition on various pathogenic fungi at the concentration of 100 mg·L−1, and presented broad-spectrum antifungal activities. Further studies also indicated that compounds 7e and 7k still showed some inhibitory activity against Pestallozzia theae, Sclerotinia sclerotiorum and Gibberella zeae on rape plants at lower concentrations, which could be optimized as a secondary lead for further research.

In vitro activity of miconazole, salicylic acid and benzoic acid against T.richophyton mentagrophytes was done on Sabouraud’s dextrose agar. The inhibition zones were measured in cm. 2.8 cm, 1.5 cm and no inhibition zone were reported for miconazole, salicylic acid and benzoic acid respectively. Synergistic effect of salicylic acid and benzoic acid against T. mentagrophytes was done using two different bases of cream lanette 20% and aqueous cream 30/70. Four different formula each one contain 2% miconazole with different concentrations of salicylic acid and benzoic acid were used. Biggest inhibition zone (5 cm) was observed of lanette cream which contains 2% miconazole, 3% salicylic acid and 6% benzoic acid.
