Morphological changes of WI-38 cells under an inverted phase contrast microscope (10×). (A) Control with no treatments; (B) Cells incubated only with H₂O₂ (800 µM) for 3 h. Images C to J represent the cells pre-incubated with test compounds for 48 h followed by H₂O₂-induced oxidative injury: (C) Stearic acid derivative of Q3G; (D) Oleic acid derivative of Q3G; (E) Linoleic acid derivative of Q3G; (F) ALA derivative of Q3G; (G) EPA derivative of Q3G; (H) DHA derivative of Q3G; (I) Q3G and (J) Quercetin.
