Inhibitory effects of selected plants on the growth of pathogenic fungi
Plants extracts and essential oils were evaluated for antifungal properties, against five pathogenic fungal species (Trichophyton rubrum, Aspergillus niger, Candida albicans, Fusarium solani and Cryptococcus neoformans). Inhibitory effects on the production of fungal biomass and minimum inhibitory concentration were highly active even at lower concentration (2 µl/ml). On the basis of ability to test fungi Mentha piperita and Cymbopogon citratus was most inhibitory resulting at 95% reduction in the biomass was recorded against Fusarium solani, Rhizopus microsporus and Cryptococcus neoformans. The results confirmed that the highest antifungal activity of Mentha piperita and Cymbopogon citratus essential oil recorded here could be correlated to the presence of high level of oxygenated monoterpenes. Mentha piperita and Cymbopogon citratus essential oil (2-16µl /ml) significantly inhibited the growth of Fusarium solani, Rhizopus microsporus and Cryptococcus neoformans suggesting the potential value of Cymbopogon citratus essential oil for the treatment of various fungal diseases.
