Fig. 3From: Verbesina encelioides: cytotoxicity, cell cycle arrest, and oxidative DNA damage in human liver cancer (HepG2) cell lineFlow cytometric analysis of intracellular ROS generation in HepG2 cells exposed to Verbesina encelioides (VE) extract for 24 h. Panel a shows the representative spectra of fluorescent DCF as a function of Verbesina encelioides extract concentration. Panel b exhibits the comparative analysis of the fluorescence enhancement of DCF with increasing concentrations of Verbesina encelioides extract. Each histogram represent the values of mean ± SD of three independent experiments. *p < 0.05, **p < 0.01 versus controlBack to article page
