Abstract The volatile fractions isolated from Prangos peucedanifolia Fenzl leaves and flowers were investigated for their phytochemical composition and biological properties. Flower and leaf hydrodistillation afforded 3.14 and 0.49 g of yellowish oils in 1.25 and 0.41% yields, respectively, from dry vegetable materials. According to the GC‐FID and GC/MS analyses, 36 (99.35% of the total oil composition) and 26 compounds (89.12%) were identified in the two oils, respectively. The major constituents in the flower volatile fraction were β ‐pinene (35.58%), α ‐pinene (22.13%), and β ‐phellandrene (12.54%), while m ‐cresol (50.38%) was the main constituent of the leaf volatile fraction. The antimicrobial activity was evaluated against several bacterial and fungal strains, on the basis of the minimum inhibitory concentration ( MIC ) by the micro‐ and macrodilution methods. The two volatile fractions showed moderate antifungal and antibacterial activities, especially against Trichophyton rubrum ( MIC of 2×10 3 μg/ml), Streptococcus mutans, Streptococcus pyogenes , and Staphylococcus aureus ( MIC ≤1.9×10 3 μg/ml for all).
