【 摘 要 】

The proximate analysis and fatty acid composition of seeds and leaves were determined by analyzing samples of identified leaves and seeds of Senna Singueana using A. O. A. C (1990) methods. The results of analysis showed that the seeds of Senna Singueana contain crude protein (14.88%), crude fiber (15.85%), moisture (4.07%), total ash (7.67%), total carbohydrate (55.68%), total sugar (.078%) and total oil percentage (1.85%).The results of proximate analysis of, Senna Singueana leaves showed that the crude protein (11.38%), crude fiber (1.36%), moisture (2.92%), total ash (6.93%), total carbohydrate (74.09%), total sugar (.08%) and total oil percentage (3.32%) The fixed oils extracted from seeds and leaves were evaluated for chemical composition. The GC-MS analysis showed the presence of various saturated and unsaturated fatty acids such as Stearic acid (5.330%), Oleic acid methyl ester (1.986%), Behenic acid methyl ester (3.06%) and palmatic acid methyl ester (1.515%) of Senna Singueana leaves and the fatty acid found in the Seeds part were Eicosanoic acid, methyl acid (4.17%), Hexadecanoic acid, methyl acid (1.515%), Teteracosanoic acid, methyl acid (3.64%) and 16 - Octadecenoic acid, methyl ester(26.01%). Also leaves and seeds indicate the presence of calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), magnesium and copper at different concentrations.
