Abstract:
Cyanogenic glycosides, Phytic acid, total and soluble oxalates are common antinutrlents associated with plant
tissues. The levels or Ihese substances wore doterrnlnod In tho leory voqctabtcs "Zognla" (Molinga.proygospomio), spinach
(1II11.110n(/1II5 cn/(!nlfls). O,III'r lonl (VelOnicR omydalinR) nnd "Yakuwa" (Uibiscus sabcfatlrra) and tho legl/lTleR.COW[l<H1 (Vigna
ungfliculata). Croundnut (llracliis "ypogOD), Bnmbata nul (Voanzola subno; and soybean (Glycin nllJx) which are commonty
ealen In Northern Nigeria. 1he results show that the legumes exhibited the highest mean values of all the antinutrients with
cowpea and Bambara nut exceptionally high in cyanoqenic glycoside and oxalate respectively. "Zogala" with the highest
antinutrients among the veget<tbleshas only about 40 - 50% of the highest levels found In the legumes. A significant (P -e
003) decrease in tile levels of all the antinu1rientsin all samples was observed after cooking. The decrease was significantly
(P < 0.03) .higher in tile legumes cornparedwith the vegetables
