Abstract

Vernonia galamensis, a plant native to Africa, is an excellent source of an epoxy oil of high potential for use in the chemical industry. Vernonia oil was obtained by Soxhlet or room temperature extraction from seeds of accession V-001 of V. galamensis var. ethiopica ssp. galamensis grown in Israel. Room temperature extraction yielded 43-44% of vernonia oil containing a relatively high amount of vernolic acid (72-80%). Vernonia oil was reacted with aliphatic and aromatic diamines to give potential high-value products. In the reaction with aliphatic diamines, amidation gave rise to fatty acid bisamides containing epoxy groups. The reaction of V. galamensis oil with aromatic diamines produced either linear or cross-linked polymers, depending on the reaction conditions.
