The seed oils containing unusual fatty acids are being exploited for industrial utilization and are highly important to the production of oleochemicals. Ochrocarpus africanus belongs to Guttiferea plant family which is a rich source of viscous, non-edible and renewable crude oil (30.0%) containing ricinoleic acid (20.0%), vernolic acid (12.0%), malvalic acid (6.0%) and sterculic acid (4.0%) as its unusual fatty acids along with the other normal fatty acids like lauric acid (1.1%), myristic acid (1.3%), palmitic acid (28.2%), stearic acid (27.4%), oleic acid (trace) and linoleic acid (trace). The present investigation describes the unique occurrence of unusual fatty acids in O. africanus seed oil as well as in Guttiferea plant family. These fatty acids have been characterized by UV, FTIR, 1H NMR, 13C NMR, MS, GLC-techniques and chemical degradations.
