In vitro Antioxidant and Anticancer Activity of Cyanobacteria

Some cyanobacteria have therapeutic properties related to anticancer, antioxidant and antibacterial activity. The aim of the present study was to determine the polyphenol content together with antioxidant and anticancer activity against Ehrlich Ehrlich Ascites Carcinoma cell line in vitro of Anabaena oryzae, Calothrix marchica and Spirulina platensis‏, selecting the best alga for further investigations. The results indicate that methanol extracts of S. platensis‏ has the greatest polyphenol content, together with the highest antioxidant and anticancer activity in vitro followed by A. oryzae and C. marchica respectively. Based on gas chromatography/mass spectrometry analysis of S. platensis‏ methanol extract show that the most dominant content was octadecenoic acid methyl ester (ω- 9).
