Abstract :

The main objective of the present study was to determine the nutritional value of Caulerpapeltata and Centroceras clavulatum collected from Thikkodi coast by analysing their biochemical,phytochemical and antioxidant activity.The samples were extracted using different solvents of acetone,ethanol,water and petroleum ether.In this study the phytochemical constituents such as alkaloids, steroids, flavonoids, phenols, coumarin, cardiac glycoside, tannins, terpenoids, saponins and biochemical constituents such as protein, carbohydrate and the DPPH free radical activity of selected seaweeds collected from Thikkodi coast were analysed.The present study provides useful information of all phytochemicals present in both the algae,Caulerpa peltata and Centroceras clavulatum.It shows variations in different solvents because of its differential solubility. Most of the phytochemicals were found absent in its petroleum ether solution because they are less soluble in petroleum ether. Compared to Centroceras clavulatum, Caulerpa peltatashowed high amount of protein and carbohydrate. Both these algae have antioxidant activity. In the present study, the seaweed extracts have high DPPH scavenging capacity, which increased with increasing concentration.A positive relation has been documented between antioxidation capabilities and total flavonoid content for Caulerpa peltata and Centroceras clavulatum. Their antioxidant activity shows an inverse relation with the phenolic content. The results suggest that both the algae can be used as antioxidants in the field of medical science.
