Ongokea is a genus of flowering plants, with one species Ongokea gore (Boleko).[1] In the APG IV system, the genus is placed in the family Olacaceae.[2][1] Other sources place it in the segregate family Aptandraceae.[3]
Its native range is Western Tropical Africa to Angola,[1] and is notable for the seeds of its edible fruits containing an industrially-useful oil that can undergo explosive polymerization reactions at elevated temperatures.[4] This oil is curious for being rich in diacetylenic and hydroxy-diacetylenic fatty acids, primarily isanic and bolekic acid - that is, instead of a typical single-bonded fatty acid backbone, these acids contain multiple (thermally unstable) triple bonds.[5]
