Dawodu (2009) reported 14.62% of liquid brownish yellow oil with 0.845 specific gravity, 1.96 acid
value and 112.5 saponification value. Foma and Abdala (1985) have found oleic acid followed by
linoleic and palmitic acids as predominant FAs in this plant. A review of plant seed oil content, oil
characteristics and FA compositions of oils from these plant species are presented in Tables 4 and 5.
