Abstract
Extract of Eugenia aromatica (L.) Baill. (Myrtaceae) was tested for antifungal activity.
In this study, phytopathogenic molds, Alternaria sp. and Fusarium sp. causing leafspot and wilt disease in Brassica spp., and Botrytis sp. and Septoria sp., causing gray mold rot in roses and leafspot in chrysanthemums respectively, were used as test organisms.
The extract of Eugenia aromatica, 0.01 – 1.00% concentration incorporated in PDA, provided inhibitory activity against all tested molds. Botrytis sp. and Fusarium sp. were completely inhibited at a concentration of 0.05%, while Alternaria sp. and Septoria sp. were completely inhibited at concentrations higher than 0.30%. Separation by preparative-TLC and confirmation by TLC-bioassay using Cladosporium cladosporioides as a diagnostic fungus distinguished two active compounds, eugenyl acetate and eugenol.
