Polyphenol extract of Phyllanthus emblica (PEEP) induces HeLa cell apoptosis. HeLa cells were treated with 0 mg/ml PEEP (A), 150 mg/ml PEEP (B) for 48 hours. The cells were harvested and resuspended in Guava Nexin. Cell cycle stage was determined by flow cytometry. The panels inside the image are marks of the quadrants, cells in the left lower quadrant are living cells, in the right upper quadrant are dead cells, and in the right lower quadrant are apoptotic cells.
