Studies on the seed oils of Parkia biglobosa and Parkia bicolor.

The seed oils of Parkia biglobosa and Parkia bicolor (Mimosaceae) have been analysed for their possible edible utility and to provide some physical data on both oils. The fatty acid composition of the oils was identified. Six major fatty acids were identified in the oil of P. bicolor while five were identified in that of P. biglobosa by Gas Chromatography (GC) and Gas Chromatography-Mass Spectroscopy (GC-MS). The two oils contained five similar fatty acids in almost the same ratios. Arachidic acid was the most abundant fatty acids (greater than forty per cent) in both oils. Other fatty acids in the oils were behenic, stearic, palmitic and linoleic acids. The sixth fatty acid in P. bicolor was an odd number of carbon atom and un unsaturated fatty acid (C20H37COOH) named bicolargic acid. The oils were also found to be non toxic.
