For agar diffusion, extracts at the concentration 1 mg/mL were used. Diameter of inhibition zones (IZ) in mm: >18 mm: sensitive; 14–18 mm: intermediate; <14 mm: resistant [55,56]; Pt, petroleum ether extracts; CHCL3, chloroform extracts; EtOAc, ethyl acetate extracts; NA, Not active. IZ results as mean ± SEM of five measurements. MIC in µg/mL. The observed differences between the sample means of the inhibition zones (the stem bark and wood extracts) against the tested fungi did not differ significantly.
