Essential oils of two wild-growing Artemisia species collected from west of Iran during the flowering stage were obtained by hydro-distillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC–MS). Under the optimum extraction and analysis conditions, 23 and 19 constituents were identified in A. fragrans and A. hausskenechtii which represented 92.96% and 90.2...
