The bioassay with headspace of T. minuta and S. areira oils and their pure principal components revealed strong inhibitory activity of the root growth of Zea mays seedling. Both T. minuta and S. areira oils treatment presented an increase in malondialdehyde values from 24 to 48 h, while the main components of the essential oils, ocimenone, a pinene and limonene, presented an increase from 24 to 96 h indicating exhuasted lipid peroxidation. The T. minuta essential oil had a strong inhibitory action and oxidant effect on root of  Zea  mays than S. areira oil.
