Legend: BTHE: hexane extract; BTCE: chloroform extract; BTEE: ethyl acetate extract; BTME: methanolic extract. In each row, the values with significant differences (p < 0.05) are indicated by different superscript letters (a, b, c, d). The results are expressed as the mean ± standard deviation calculated from three independent assays performed in triplicate (n = 3).
