The cytotoxicity-directed fractionation of MeOH extract of Terminalia chebula fruits led to the isolation of three hydrolyzed tannins and a related compound, gallic acid(1), $1,2,3,4,6-penta-O-galloy-{\beta}-_D/-glucopyranose(II)$,. chebulagic acid (III) and chebulinic acid(IV), as active principles. They were shoen to exhibit moderate cytotoxicity against cultured human tumor cell lines including A-549, SK-OV-3, Sk-MEL-2, XF-498 and HCT-15 in vitro.
