Abstract: Purpose: The aim of this study was to observe the anti-oxidative activity of spirulina platensis and to explore anticarciogenic mechanism of spirulina platensis. Methods: Single cell gel electrophoresis (SCGE) assay was used to observe and evaluate the anti-oxidative activity of spirulina platensis. Results: T he results demonstrated that Spirulina platensis could protect CHL cellular DNA from damage induced by hydroxy free radical in dose-dependent manner. Conclusion: The anti-oxidative activity of spirulina platensis might plays an important role in cancer chemoprevention.
