Qualitative and Quantitative Analysis Of Phytochemical Variation in G. corticata And K. alvarezii

Seaweeds are one of the most important renewable wealth of marine source which have been used as food in diet for centuries. They are source of wide range of secondary metabolites such as carotenoids, dietary fibres, proteins, essential fatty acids, vitamins and minerals. For these study seaweeds samples of Gracilaria corticata and Kappaphycus alvarezii were collected from Rameshwaram. These samples were subjected to preliminary phytochemical screening and then quantitative estimation of photochemical. The samples were found positive for alkaloids, anthraquinones, flavinoids, lignin, proteins and saponins. In our observation phenolic compound and flavonoids were founf in these species which have been reported to be potent free radical scavengers. In our study Gracilaria corticata was found to contain more phenolic content and flavonoids compared to Kappaphycus alvarezii.
