DPPH antiradical activity and total phenolic content of methanol and ethanol extracts from macroalgae (Ulva rigida) and microalgae (Chlorella)

Abstract

INTRODUCTION: Algae are widely popular as dietary supplement. Furthermore, they can be a great source of antioxidants (pigments, alkaloids, carotenoids, phenolic acids, sulfated polysaccharides and long-chain polyunsaturated fatty acids etc.) and can be used instead of synthetic ones. The different nutrient compositions of algae depend on class, species, habitats, maturity, and environmental conditions.
