Abstract
The seasonal variation of the marine seaweed Laurencia obtusa was analysed for total carbohydrates, lipids and proteins, photosynthetic pigments free amino acids, fatty acids vitamins and minerals. These results clearly depict the nutraceutical variations of the alga abundant in the shores of Kanyakumari, India during the month of April compared to that of December. Ethanolic extracts were screened for the presence of various phytochemicals like flavonoids, phenols, alkaloids, tannin, steroid and saponin using standard protocols Though there have been several reports on biochemical composition of this seaweed across India, but there are very few studies focusing on the seasonal variations in chemical composition of this seaweeds.
