Values (mean ± SD) are average of three samples of each medicinal plant material, analyzed individually in triplicate (n = 1x3 x 3), (P < 0.05); DW= dry weight; 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 within the plant materials.
