    ABSTRACT

    Introduction: Spirulina maxima was used as important nutritional source in the Aztec civilization because it is rich in proteins and vitamins. It contains various antioxidants such as phycocyanin and flavonoids. Based on abundant antioxidants, S. maxima is known to possess anti‑inflammatory effect, especially on neuronal cells. Materials and Methods: S. maxima was extracted in water and contain of phycocyanin was identified by high‑performance liquid chromatography. Cell viability test was performed with treatment of S. maxima extract. After, oxidative stress‑related mechanisms were evaluated by detecting the accumulation of reactive oxygen species (ROS) and Ca2+ influx, and decrease of mitochondrial membrane potential (MMP) level. Then, the glutathione (GSH) related assays were conducted. Results: The water extracted S. maxima exerted the neuroprotective activity by attenuating the ROS and Ca2+ formation, maintaining the MMP level, and protecting the activity of the antioxidant enzymes by increasing reduced GSH against oxidative stress compared to control. Conclusion: The results suggested that water extracted S. maxima showed powerful neuroprotective effect through the mechanism related to antioxidant activity, able to preventing the radical‑mediated cell death.
