Abstract

Oils of Zyziphus spina ( Z. spina ) and Moringa oleifera ( M. oleifera ) seeds were analyzed for physicochemical, phytochemical and lipid composition. M. oleifera seeds gave oil yield of 40.47% while Z. Spina seeds gave 30%. Refractive index, density and acid value (mg KOH g -1 ) of M. oleifera oil were 1.471, 0.81, 1.16 while Z .spina had 1.441, 0.79, 7.57 respectively. Similarly, Iodine (Wijs), Saponification (mg KOH g-1) and Peroxide (meq kg-1) values obtained for M. oleifera oil were 46.50, 166.77 and 2.16 whereas Z. spina had 86.40, 184.00 and traces respectively. The phytochemical analysis showed the presence of secondary metabolites such as saponin, flavonoids, terpenoid, sterol and balsam in M. oleifera and alkaloids, flavonoid, terpenoid, sterol and resin in Z. spina. Lipid composition showed the presence of neutral lipids, glycolipid and phospholipid in both Z. spina and M. oleifera.
