Abstract
Essential oils were obtained by hydro distillation from the aerial flowering parts of Sclerorhachis platyrachis and Sclerorhachis leptoclada, endemic plants of Iran. The antifungal activity of these essential oils was then evaluated for its effectiveness against phytopathogenic fungi, Aspergillus flavus and Fusarium verticilloides. This experiment was carried out in PDA and PDB media for determining hyphal radial growth and dry mycelium weight, respectively. The chemical composition of the essential oils was analyzed using a GC/MS system. The essential oil from S. platyrachis was found to be rich in camphor (35.5%), bornyl acetate (11.7%) and 1,8-cineole (8.0%): and the major components of essential oil from S. leptoclada were bornyl acetate (18.8%), camphor (17.7%) and δ-cadinene (6.9%). Different concentrations of the essential oils had the effects of reduced dry mycelium weight and hyphal radial growth of the fungi, Aspergillus flavus and Fusarium verticilloides. The percentages of hyphal radial growth inhibition on F.verticilloides were 72.2% and 68.9% by S. platyrachis and S. leptoclada, respectively: whereas these percentages were 70.5% and 71.1% on A. flavus from the same plants, also respectively. In addition, the maximum and minimum reductions of dry mycelium weights were 78.6% and 30.5%, respectively from the essential oil of S. leptoclada on the A. flavus and F.verticilloide fungi.
