• Resumen

  • The essential oils of five geographical populations of the Iranian Helichrysum leucocephalum were analyzed by gas chromatography and mass spectrometry (GC and GC/MS). There were 69 chemical compounds in the studied populations: trans-caryophyllene (11.2–21.44%) and α-humulene (9.37–18.68%) occurred with the highest percentage in the Abadeh-Tashk population. Some other interesting compounds obtained were:

    α-copaene (3.23–8.40%), α-pinene (2.90–7.86%), β-selinene (2.93–6.37%), and Δ-cadinene (2.50–4.74%).

    Compounds occurred in different quantities in all studied populations. A STRUCTURE analysis of the combined genetic and chemical contents showed the divergence between populations.
