A new gallic acid derivative, 1-O-galloyl-6-O-(4-hydroxy-3,5-dimethoxy)benzoyl-β-D-glucose (1) has been isolated from an H2O-fraction of MeOH extract of Combretum quadrangulare seeds. Compound 1 exhibited potent hepatoprotective activity against D-GalN/TNF-α-induced cell death in primary cultured mouse hepatocytes with an IC50 of 3.3 μM.
