Figure 3.

Anti-α-amylase activities of methanol leaves extract of W. fruticosa and its different fractions compared with the reference inhibitor acarbose. Values are shown as mean ± SEM (n = 3). (A) The percentage inhibition of α-amylase activity at four different concentrations (µg/mL). (B) IC₅₀ values (µg/mL) for α-amylase activity. Values marked with different superscript letters (a, b, c, d) in different columns signify statistical differences at p < 0.01 (Tukey’s HSD test). MEWF, methanol extract of W. fruticosa leaves; NHFMEWF, n-hexane fraction of methanol extract of W. fruticosa leaves; EAFMEWF, ethyl acetate fraction of methanol extract of W. fruticosa leaves.
