Biochecmial composition of marine brown alga Lobophora variegata from Mandapam in the South East Coast of Tamil Nadu

Sathyaseelan Thennarasan


Marine algae are well-known as a functional food for their richness in lipids, minerals, certain vitamins and also several bioactive substances like polysaccharides, proteins and polyphonies. Thus, the brown alga was analyzed for its biochemical properties for rich source of all essential nutrients which is promising as a source of pharmacognosical value. In the present study, brown alga Lobophora variegata was studied for the biochemical properties, such as Carbohydrates, protein, lipids, vitamins, sterols, fatty acid and minerals composition were carried out by using gas chromatography method and flame atomic absorption spectrophotometry method respectively. Among biochemical content total protein were present in higher quantity 23.13 ± 0.05%, followed by total carbohydrates-19.34 ± 0.10% and total lipid-0.27± 0.5%. Also the experimental alga were rich in vitamins (especially vitamin C), Fatty acids (Omega fatty acid), and minerals (calcium) respectively. Comparatively the sterols also been noted. Thus, the results of biochemical composition of marine brown alga seem to be more valuable for the nutraceutical as well as pharmaceutical industry as a potential source.
