The aim of the present research was to evaluate and compare the antiradical and antioxidant activities of extracts from Spirulina platensis. In the present study, Three extracts (Water, absolute methanol and 50% methanol in water) were analyzed for the total Phenolic compounds, phycobiliprotein content: Antiradical and antioxidant activities were evaluated using 2,2-diphenyl- 1-picrylhydrazyl (DPPH) and 2,2-azinobis (3-ethylbenzothiazoline- 6-sulfonic acid) (ABTS) radical scavenging methods.

The obtained results revealed that, absolute methanol extract recorded the highest number of antiradical units 1 mg extract followed in descending order by that of water while the lowest number was that of aqueous methanol (against DPPH and ABTS radical methods). The results indicated that selection of the cyanobacterium (Spirulina platensis) very important for consumer’s health, as it is considered as potential sources of dietary antioxidants.
