摘要：The seeds and leaves of African Locust Bean (Parkia biglobosa) were evaluated for their proximate analysis, minerals and anti-nutritional factors. Atomic absorption spectrometry was used in the determination of the levels of Ca, Mg,K, Na, Mn, Fe, Cu and Zn. Anti-nutritional Factors (ANFs), including Trypsin inhibitor, oxalates, phytates, tannins, saponins, hydrocyanic acid were also determined using appropriate techniques. The result showed that the seeds of P.biglobosa had significantly higher (p<0.05)crude protein (33.50%), crude fat (49.20%) and %dry matter (95.20%) contents compared to the leaves having crude protein(18.40%), crude fat (8.11%) and %dry matter (88.80%), while the leaves had significantly higher (p<0.05) contents of ash (13.60%), crude fibre(18.90%) and moisture (11.20%) as against the seeds havingash (4.81%), crude fibre(4.66%)and moisture (4.89%). The mineral content of the analyzed samples showed that the seeds were richer in Ca (0.703%), Mg (0.356%), K (0.211%), Na (86.729ppm), Mn (54.811ppm), Fe (69.828ppm), Cu (9.766ppm) an d Zn (12.156ppm), while the leaves recorded higher Phosphorus level (79.833ppm) than the seeds. For the ANFs, the seeds recorded higher levels of trypsin inhibitor (0.059+ 0.01), haemagglutinating un its (46.00+ 0.07) and tannins (0.51+ 0.00) than the leaves, while the leaves recorded higher levels of oxalates (0.97+ 0.00), phytates (2.16+ 0.03), saponins (1.24+ 0.00) and hydrogen cyanide (87.9 + 0.56)than the seeds. The overall results are suggestive of higher nutritional quality of the seeds than the leaves due to higher mineral contents and lower presence of some anti-nutritional factors.
