摘要: Leaf essential oils of Callistemon rigidus and Callistemon citrinus obtained by steam-distillation were assigned for their antifungal activity against Phaeoramularia angolensis. The of C. rigidus and C. citrinus were dominated the presence of 1,8-cineole (79.1% and 73.8% respectively). Fractions 6 5 isolated from C. citrinus respectively rich in1,8-cineole (100% 91.4% respectively). The determination was done by the agar medium assay. Total inhibition obtained with concentrations 6500 ppm 6000 for C. citrinus essential oils respectively. Fraction 12 citrinus rich in α-terpineol terpinen-4-ol (88.7% 10% respectively) most active showing total againstPhaeoramularia angolensis at 1500 ppm. two used showed fungicidal properties against P. angolensis and could constitute an alternative to synthetic fungicides usually citrus fruit crops. Key words: Essential oil, Callistemon citrinus, Callistemon rigidus, essential oil composition, Phaeoramularia angolensis, activity.
