The inhibitory activity of α-mangostin against β-lactamase in hydrolysing benzylpenicillin. β-lactamase used from E. cloacae; CON = control (no testing agent); AMT(1) = 1 μg/ml α-mangostin. The graph shows the remaining benzylpenicillin at the same time. Means sharing the same superscript are not significantly different from each other (Scheffe’s test, p < 0.01)
