Phyto chemical evalution and antioxidant activity of methanol extract of Loligo duvauceli Ink

Abstract

The present study, the Loligo duvauceli ink which is generated as a byproduct in processing industry, the ink samples are screened for phytochemical evalution.Large number of compounds are present in the ink like phenol, flavonoid, protein,carbohydrate, aminoacids. Among the protein, flavonoids are present in higher amount where as sterols, terpenoids, saponins are absent in the Loligo duvauceli ink. In proteins phenols flavonoids, carbohydrate are quantitatively estimated in methanol extract and partially purified form and the antioxidant activity of Loligo duvauceli ink was done by ferric thiocyanate assay and thiobarbituric acid assay the results were compared using Loligo duvauceli ink by using water as a solvent.
