  The essential oils of the fresh leaves of Polyscias guilfoylei and Polyscias balfouriana (Araliaceae) were separately prepared by hydro distillation and were characterized by gas chromatography-mass spectrometry (GC/ MS). Forty-two compounds were identified representing 79.17% and 87.77% of the whole volatile constituents of P. balfouriana and P. guilfoylei, respectively. The oxygenated sesquiterpenes represents 10.56% and 20.08% of the whole volatile constituents of P. balfouriana and P. guilfoylei, respectively. β-chamigrene and γ-muurolene were the most abundant compounds in both oil samples. The antimicrobial effect of the samples was evaluated against two gram positive and two-gram negative bacteria in addition to two fungi using agar well diffusion method. P. guilfoylei showed moderate activity against .. View More»
