Abstract

Seaweeds are marine macroscopic algae which are considered as the important living marine organisms with high nutritive value and rich bioactive compounds present in the ocean. In the current study the phytochemical, amino acid, fatty acid and vitamin profile analysis of the seaweeds were conducted which were collected along the south east coast of India. The marine brown macro alga Colpomenia sinuosa (Mertens ex Roth) Derbes and Solier as well as the marine red alga Halymenia poryphyroides Boergesen were used in this study. The relationship between the nutritive components and the variation between phytochemical, amino acid, fatty acid and vitamin profile were mainly analyzed in the current study. The present analysis revealed that phytochemical contents like alkaloids, triterpenoids, steroids and glycosides were present in higher amounts in marine red alga Halymenia porphyroides compared to the marine brown alga Colpomenia sinuosa. Similarly the amino acid analysis showed higher percentage in marine red alga Halymenia porphyroides when compared to the marine brown alga Colpomenia sinuosa. The fatty acid profile also revealed higher content in Halymenia porphyroides when compared to Colpomenia sinuosa. On the contrary the vitamin profile analysis revealed higher amounts of vitamins content in Colpomenia sinuosa rather than Halymenia porphyroides. The presence of high phytochemical, amino acid, fatty acid constituents in Halymenia porphyroides makes this seaweed more important when compared Colpomenia sinuosa which were rich in vitamin content and can be used as an important vitamin source for human and animal diet.
