Progallin A isolated from the acetic ether part of the leaves of Phyllanthus emblica L. induces apoptosis of human hepatocellular carcinoma BEL-7404 cells by up-regulation of Bax expression and down-regulation of Bcl-2 expression

After treatment with Progallin A for 72 h, using fluorescence microscope under 400× magnification, dense blue nuclear chromatin fragments of BEL-7404 cells were observed.
