From: Pleiocarpa pycnantha leaves and its triterpenes induce apoptotic cell death in Caco-2 cells in vitro
Pleiocarpa pycnantha and isolated compounds apoptosis is mediated by caspase3/7 activation. a Treatment of cells with various concentration of extract P for 6–24 h (P) treated with various concentrations for 24 h. b Cells were treated with increasing concentrations of compound C2 for 6–24 h. c Measurement of caspase 3/7 activity when cells were treated with different concentrations of compound C3 for 6–24 h. Data are presented as mean ± SEM,***P < 0.001, **P < 0.01 and *P < 0.05 compared with control
