*2.5. Morphological Study under Light and Transmission Electron Microscope*

Light and electron microscope observations were performed according to Gutiérrez-Praena et al. (2019) [30]. Cultured cells were exposed to three different concentrations of the extract, the EC50 value, and their fractions (EC50/2, EC50/4). HepG2 were exposed to 7.79, 15.59 and 31.18 μg/mL and Caco-2 cells were exposed to 13.90, 27.88, and 55.77 μg/mL.
