<p></p> <p><b>New page</b></p><div>&#039;&#039;&#039;Vernonia oil&#039;&#039;&#039; is extracted from the seeds of the &#039;&#039;[[Vernonia galamensis]]&#039;&#039; (or ironweed), a plant native to eastern [[Africa]].<br /> <br /> :&#039;&#039;Vernonia seed contains about 40 to 42% oil of which 73 to 80% is [[vernolic acid]]. This is about 30% more vernolic acid than the best varieties of [[Venonia anthelmintica|V. anthelmintica]]. Products that can be made from vernonia include epoxies for manufacturing [[adhesive]]s, [[varnish]]es and [[paint]]s, and industrial coatings. The low [[viscosity]] of vernonia oil would allow it to be used as a nonvolatile [[solvent]] in [[oil-based paint]]s since it will become incorporated in the dry paint rather than evaporating into the air.&#039;&#039;&lt;ref&gt;{{cite book<br /> | url=http://www.hort.purdue.edu/newcrop/afcm/vernonia.html<br /> | title=Alternative Field Crops Manual<br /> | chapter=Vernonia<br /> | author=T.M.

Vernonia oil has superior qualities in this application, compared to these oils.&lt;ref&gt;{{cite web<br /> | title=Vernonia<br /> | author=David A.
