Antifungal Property of Essential Oil Extracted from Zanthoxylum armatum (Timur)

Abstract

The aim of this research work was to test the effect of essential oil of Zanthoxylum armatum (timur) originated from Salyan (Nepal) against five isolated fungi i.e. Aspergillus sp., Alternaria sp., Penicillium sp., Cladosporium sp. and Helminthosporium sp. The essential oil yield of sample from Salyan was 2.29 %. Different concentrations i.e. 5µl, 10µl, 15µl and 20µl of essential oil were used to determine zones of inhibition. The zone of inhibition was highest against Cladosporium sp. at all concentrations, while it was lower against Penicillium and Helminthosporium sp. MIC values of essential oil of Zanthoxylum armatum were found to be 0.16mg/ml, 0.14mg/ml, 0.4mg/ml, 0.1 mg/ ml and 0.4 mg/ml against Aspergillus sp, Alternaria sp, Penicillium sp, Cladosporium sp and Helminthoaporium sp respectively
