Qualitative and Quantitative Analysis of Phytochemical Studies on Selected Seaweeds Acanthopora Spicifera and Sargassum Wightii

The sample for the study constitutes acanthopora spicifera from red seaweed and sargassum wightii from brown seaweed. They were freshly obtained from mandapam and elatharavai coast of erwadi and were rinsed in seawater and the packed in aseptic bags and brought to the laboratory for further processing. The extracts were subjected to phytochemical analysis to secondary metabolites both qualitatively and quantitatively p. By preliminary phytochemical screening of eight different chemical compounds (alkaloids Teripioids, steroids, tannin, saponins, flavonoids, Polyphenols, glycosides) were tested in four different extracts. The present investigation revealed that Saponins did not show any positive result for their presence in any of the five extracts tested. Among the five different extracts, petroleum ether and methanol extract showed the presence of maximum number (8) of compounds. Next to that, Acetone extracts showed seven compounds. Water extracts showed five compounds and ethanol extracts showed only two compounds. The quantative phytochemical analysis revealed that the highest total phenol (216.65±17.38) and flavanoid (358.25+18.21) was in the brown seaweeds. wightii. The highest tannin compound was recorded in acanthopora spicifera seaweed. (28.54+ 0.89).
