The present research focused to identify the nutritive compounds present in the seaweed Kappaphycus alvarezii. The fresh solvent extracts of K.alvarezii were found to be rich in total carotenoid content and vitamin C. The concentration of vitamin C was found to be 9.2 mg/g.f.wt, β-carotene 6.5 mg/g.f.wt and total carotenoid 7.9 mg/g.f.wt. k. alvarezii extracts revealed macromolecules contents such as carbohydrate contents of 29mg, Protein 18.7mg and fiber content 3.7mg /100 g of dry wt. Micronutrients were estimated that calcium content was 35.2mg/100mg and iron content found to be more in 1.14 mg, phosphorus content of 18.7 mg, magnesium 20.6mg /100 mg of d.wt, sulphate 20.2mg, sodium 22.4mg, potassium 13.4mg. The results show that, the presence of bioactive compound prepared from experimental species showed economic value, quality as polysaccharide, it can be concluded that the K.alvarezii may serve as functional food with vital pharmaceutical and biological value.
