Values (mean ± SD) are average of three samples of each BGS sample, analyzed
individually in triplicate (n = 1x3 x 3), (P < 0.05); Superscript letters within the same
row indicate significant (P< 0.05) differences of means within the extracting solvent;
Subscript letters within the same column indicate significant (P< 0.05) differences
of means among the extracting technique.
