| Summary: | The key objective of this study was to determine the yield and chemical composition of eight commercial samples and one collected sample of common vervain (<i>Verbena officinalis</i> L.) herb essential oil (EO) originating from seven different countries, and subsequently, to assess its potential for treating anxiety and depression. According to GC-MS analysis, 90 compounds were identified, 49 of which were discovered for the first time in <i>V. officinalis</i> EO. The plants with the highest oil content are from Greece (4.7 mL/kg) and South Carolina, USA (5.2 mL/kg). The chemical markers for the studied chemotypes of EO of <i>V. officinalis</i> are the terpenoids <i>o</i>-cymene, <i>p</i>-cymene, <i>L</i>-carvone, thymol, carvacrol, α-curcumin, hexahydrofarnesyl acetone, phytol, <i>(E)</i>-β-ionone, and phenylpropene anethole. The chemotype from the UK demonstrated the greatest affinity to the continuum under study; it has the highest levels of similarity—85.2% with the chemotype from Greece, 69.4% with the chemotype from the USA, 68.2% with the chemotype from Estonia (2), 58.7% with the chemotype from Germany, and 58.6% with the chemotype from Hungary. The chemotypes identified have the potential for use in the treatment of anxiety and depression. |
