Abstract:

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 gamma-tocotrienol content, included all the accessions of sect. Orobanche. The second one, exhibiting high gamma-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 delta-tocopherol content. Differences for tocochromanol derivatives within sect. Trionychon were paralleled by differences in the fatty acid profile, with the high delta-tocopherol class having also a higher oleic to linoleic acid ratio.
