ABSTRACT
The analysis for the antinutritional composition of turmeric (Curcuma longa) was carried out using standard analytical method. The result of the analysis were as follows; phytate 6.29±0.07, tannin 4.21±0.02, oxalate 8.95±0.51 and Hydrogen cyanide 2.91±0.49 comparing the result with the lethal dose limit, it reveals that the concentration of the analyzed anti nutrient were within the permissible limit. Hence, the plant sample is recommended for human consumption.
