Investigation of antioxidants from wild Spirulina platensis in Iran

Spirulina micro-algae is a valuable green-blue algae, which due to its nutritional value, its medicinal properties, high protein, vitamins, minerals, and natural pigments It is widely used in various food, health and beauty industries, human food supplements, livestock, poultry, And aquatic animals. Free radicals cause many diseases in humans. Antioxidants eliminate free radicals that are active and destructive. Experts predict that our communities will face a cancer tsunami in the future, with new and modern uses of these algae having anticancer compounds to cope with cancerous diseases. In this study, the total antioxidant activity of the methanolic extract of Spirulina in three concentrations (۱۰, ۲۰, ۳۰ ppm) was calculated using the DPPH method and was compared with ascorbic acid. Also, the assessment of Chlorophyll a, carotenoid, and Phycobiliproteins measurements of proteins measured in a ۵-to-۲۰-day growth period under laboratory conditions. Results: Based on the results of antioxidant activity measurements, the total alcoholic extract of algae at ۱۰, ۲۰, ۳۰ ppm concentration was ۲۳.۱۸%, ۴۰%,۷۱.۴۲%, chlorophyll a, carotenoids, allophycocyanin, phycocyanin, and phycoerythrin was calculated respectively ۶.۸, ۳. ۲, ۴۱.۰۸, ۲۸, ۱۴.۸ µǥ/mgdw. In DPPH, the amount of ic۵۰ of spirulina platensis calculated to be ۲۳.۶۹%. Conclusion: In this study, the antioxidant activity of the spirulina platensis strain of Iran has been investigated. According to studies, this strain was introduced as a rich and new source of natural antioxidants for further research and industrialization.
