The aim of the present paper is to evaluate the photochemicals, lipids and proteins of green algae Chlorococcum sp. Stigeoclonium sp. and Enteromorpha sp. The green algae Chlorococcum sp. Stigeoclonium sp. and Enteromorpha sp. showed the phytochemical constituents like Flavonoids and phenols compounds. The presence of a variety of chemical constituents, such as phenols, flavonoids were analyzed in three green algae by TLC. In the present investigation Enteromorpha sp. showed the highest amount of Flavonoids and phenol was found to be highest in Stigeoclonium sp. The quantitative estimation in above three species showed the presence of highest amount of lipids in Stigeoclonium sp and highest amount of proteins was estimated in Chlorococcum sp.
