The objective of this study was to evaluate the anticancer effects of gamma-irradiated apigenin against various human cancer cells. Structural changes were analyzed by high pressure liquid chromatography. Gamma-irradiated apigenin showed a new peak distinguished from the main peak of apigenin (non-irradiated). Cytotoxic effects in human normal cells (HS68) were not observed upon gamma-irradiated and non-irradiated apigenin treatment. However, gamma-irradiated apigenin treatment significantly increased cytotoxicity against non-small lung cancer cells. For apoptosis induction activity tested by Annexin V/PI staining, gamma-irradiated apigenin showed a stronger effect than non-irradiated apigenin, and the level of reactive oxygen species was apparently elevated by gamma-irradiated apigenin treatment. These results suggest that gamma irradiation could be an effective method for development of a new physiological compound from an original compound by inducing structural changes.
