Values expressed are means ± S.D. of three parallel measurements. TE, Trolox equivalent; EDTAE, EDTA equivalent; EA, ethyl acetate; MeOH, methanol. Different letters indicate significant differences in the extracts (p < 0.05). Superscript letters (a,b,c) indicate different levels of statistical significance.
