Abstract:The present paper highlights the effect of Pb/Cd‐stress and/or mycorrhizal colonization by Glomus Intraradices on yield, chemical composition, cytotoxicity and antimicrobial activity of Mentha x piperita L. essential oil. Our findings showed that mycorrhizal colonization could be used to improve the essential oil yield of M. x piperita, either in non‐stressed or Pb/Cd‐stressed plants. GC–MS analysis revealed three chemotypes: linalool/pulegone (32.6/30.8%) chemotype in essential oils of non‐mycorrhizal Pb‐stre… Show more
