The evaluation of tocochromanols (tocopherols and tocotrienols) in 49 accessions from 21
Orobanche species revealed three well separated groups. The first one, characterized by high γ-tocotrienol content, included all the accessions of sect.
Orobanche. The second one, exhibiting high γ-tocopherol content, comprised the accessions of
O. arenaria Borkh. and
O. purpurea Jacq. (sect.
Trionychon Wallr.). All the other accessions of this section presented high δ-tocopherol content. Differences for tocochromanol derivatives within sect.
Trionychon were paralleled by differences in the fatty acid profile, with the high δ-tocopherol class having also a higher oleic to linoleic acid ratio.
