These pigments were known to possess several biological properties. Specifically, fucoxanthin is present in several micro- and macro-algae and known to exhibit a remarkable antioxidant, cytotoxic and, hypoglycemic activity. These pigments are being used in several health care products however; their feeding deterrent activity is not well understood. Here, we report the isolation of fucoxanthin and pheophytina, from this algal species by chromatographic techniques and their characterization on the basis of FTIR, UV-Vis, NMR and mass spectroscopic data. Additionally, feeding deterrent effects of the pigments on shrimps have been investigated by performing a feeding assay in an aquarium.
