„The field and morphological observation of O. gratissimum accessions allowed us to identify six types within this species, based mainly on leaf and stem indumentum and inflorescence format. Leaf shape and size differences were also observed. The essential oils analyses of all accessions allowed us to identify three chemotypes (eugenol, thymol, and geraniol), which were also possible to identify in the field by organoleptic evaluation of each accession.“
Eugenol-type oils had eugenol 44.1-62.6%, thymol 0.3-12.7%, spathulenol 9.9-25.3%, and α-copaene 0.7-2.4%
Thymol-type oils had thymol 37.2-44.3%, eugenol 2.1-3.7%, and α-copaene 4.1-14.3%.
One geraniol-type oil had geraniol 85.4%.
