In the present study antioxidant, free radical scavenging activity, total phenolics, total carotenoids, vitamin-C and vitamin-E contents of four algal species were carried out to expand their utilization in pharmaceutical and food industry. Fractions rich in phenolics were extracted from four Red algal species using methanol as solvent and Free radical scavenging activity was studied using DPPH photometric assay. Gracilaria corticata exhibited higher levels of radical scavenging activity, total phenolics, and high Vitamin C and vitamin E contents. Whereas, carotenoids are rich in Gracilaria corticata.
