12MAP: 12 months after planting (dry season); 15MAP: 15 months after planting (raining season); TE: Trolox equivalent; dw: dry weight; ND: not detected; /: unknown months of the harvests. M1, M2, M3, and M4 were commercial gari collected from Abattoir Maroua and Bertoua markets, respectively. Values followed by different letters in each column are different () significantly.
