    Background and Aim: The leaves of Colocasia esculenta is eaten as vegetable and thus, the concentrations of antinutritional factors in ethanol extract of raw C. esculenta leaves were determined. Methods: The concentrations of oxalates, saponins, tannins, alkaloids, lectins, phytates, trypsin inhibitors and cyanogenic glycosides in ethanol extract of raw C. esculenta leaves were determined using standard analytical methods. Results:The mean concentrations (in mg/g) of oxalates, saponins, tannins, alkaloids, lectins, phytates, trypsin inhibitors and cyanogenic glycosides were found to be 13.23 ± 0.29, 9.94 ± 0.08, 7.38 ± 0.06, 6.62 ± 0.03, 4.63 ± 0.02, 3.41 ± 0.01, 2.04 ± 0.02 and 0.97 ± 0.01 respectively. The results reveal that raw leaves of C. esculenta contain very high concentration of oxalate, moderate concentrations of saponins, tannins, alkaloids, lectins and phytates in order of decreasing concentrations, low concentration of trypsin inhibitors and very low concentration of cyanogenic glycosides.Conclusion: Experimental findings imply that the consumption of raw C. esculenta leaves may portend some adverse health implications.
