 "... flowering aerial parts of wild Achillea millefolium growing on the Mediterranean coast (Sardinia Island, Italy) and on the Atlantic coast (Portugal- Serra de Montemuro) were used as a matrix for supercritical extraction of volatile oil with CO2 (SFE).... The results showed the presence of two type oils. The Italian volatile extracts (SFE and essential oil) are predominantly composed by α-asarone (25.6-33.3%, in the SFE extract and in the HD oil, respectively), β-bisabolene (27.3-16.6%) and α-pinene (10.0-17.0%); whereas the main components of the Portuguese extracts are trans-thujone (31.4-29.0%), trans-chrysanthenyl acetate (19.8-15.8%) and β-pinene (1.2-11.1%)." \\ "... flowering aerial parts of wild Achillea millefolium growing on the Mediterranean coast (Sardinia Island, Italy) and on the Atlantic coast (Portugal- Serra de Montemuro) were used as a matrix for supercritical extraction of volatile oil with CO2 (SFE)....

 The yields of oil in 14 commercial samples of yarrow ranged from 0.1%-1.0% (12 samples were in accordance with the European Pharmacopoeia requirements, demanding not less than 0.2%). The most important components of the oils were chamazulene (0.8-44.3%), β-pinene (tr-23.3%), sabinene (0-16.5%), bornyl acetate (tr-15.8 %), (E)-β-caryophyllene (2.5-14.3%), (E)-nerolidol (tr-9.6 %), 1,8-cineole (tr-9.6 %), and germacrene D (0.2-7.8 %). \\ The yields of oil in 14 commercial samples of yarrow ranged from 0.1%-1.0% (12 samples were in accordance with the European Pharmacopoeia requirements, demanding not less than 0.2%).
