Inhibitory effects on Matrix metalloproteinase (MMP)-2 and MMP-9 by mango seed kernel extract (KMHE; a) and gallic acid b as shown by SDS-PAGE zymography; percent inhibitions of MMP-2 c and MMP-9 d by four different concentrations of KMHE and gallic acid, specifically 0.1, 0.25, 0.5, and 1 mg/ml, after a 48 h incubation. C0: control at the initial timepoint; C48: control after the 48 h incubation
