Objective To investigate the effects of total alkaloids of tripterygium hypoglaucum hutch (THHta) on the proliferation and apoptosis of human colon cancer cell line HCT116. Methods The effects of THHta on the proliferation of HCT116 cells were assessed by MTT assay. Morphological changes of HCT116 cells were observed with invert microscopy and fluorescence microscopy. The cell cycle distribution and apoptosis of HCT116 cells were examined by flow cytometry (FCM). The expression of active caspase-3 and cleaved PARP were detecte
d by Western blot assay. Results THHta inhibited the proliferation of HCT116 cells in a concentration- and time-dependent manner. The IC

values of THHta which affected HCT116 cells for 48 and 72 h were less than 20 μg/ml. THHta (10 μg/ml) increased the percentage of cells at the G
