The dark colored crude oil was degummed with water, treated with activated charcoal and bleached with a neutral agent, to give a light colored oil (Lovibond: 0.9 red, 3.5 yellow). Gas chromatographic/mass spectrometric analysis of the refined oil indicates a relative fatty acid composition of 79-81% vernolic (cis-12,13-epoxy-cis-9-octadecenoic) acid, 11-12% linoleic acid, 4-6% oleic acid, 2-3% stearic acid, 2-4% palmitic acid, and a trace amount of arachidic acid.
