In Vitro Antioxidant Activity of Selected Seaweeds in the Philippines (original) (raw)

The increasing amount of free radicals in the environment from both exogenous and endogenous sources make intake of antioxidants essential. This study focused on investigating the antioxidant properties of acetone, chloroform, and ethanol extracts of four seaweeds commonly found in the Philippines, namely: Caulerpa lentillifera, Caulerpa racemosa, Kappaphycus alvarezii, and Hydropuntia edulis using the DPPH assay. Results show that all seaweed samples exhibited antioxidant activities in all solvents used. Results show that all seaweed samples showed significant antioxidant activity. Between the two batches of collection of C. lentillifera and K. alvarezii, batch 1, which was collected in October 2016, showed significantly higher antioxidant activity in comparison to the activity of batch 2, which was collected in January 2017. With regards to the solvents used, acetone extracts demonstrated the highest antioxidant activity among all seaweed species. Results of the study can help fur...
