Chemical composition and bioactivities of essential oils from different plant parts of Ferula pseudalliacea Rech.f. as an endemic plant from Iran

The essential oils of leaf, flower, immature and mature fruit from Ferula pseudalliacea (Apiaceae) which grow wildly in Iran as an endemic plant were obtained by hydro-distillation and subsequently analysed by GC-FID and GC-MS. The oils obtained in yields 0.4-4.0% (w/w) and the analysis of GC-MS/FID chromatogram was resulted in the identification of 43-47 compounds, representing 90.9 - 96.7% of the total oils. alpha-Pinene was the main compound in all samples. The oils exhibited mild activity against Bacillus pumilus, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus with or more than 15 mm zones of growth inhibition and MIC values of 9-15 mg/ml. Essential oil of immature and mature fruits showed potent antioxidant activity with IC50 values of 35.4 +/- 0.4 and 39.1 +/- 0.4 mu g/mL, respectively. So, this plant as an antibacterial and antioxidant agent can be useful in food and medicine industry.
