A REVIEW ON THE PHARMACOGNOSTICAL, ECOLOGY AND PHARMACOLOGICAL STUDIES ON MARINE RED ALGAE – HYPNEA VALENTIAEAbstract
Seaweeds are the potential marine living resources in the world. More than 20,000 seaweeds are distributed throughout the world, of which only 221 (1.1%) are commercially utilized, which includes 145 species for food and 110 species for phycocolloid production. The biodiversity of the marine environment and the associated chemical diversity constitute a practically unlimited resource of new active substances in the field of the development of bioactive products. Carrageenans are galactans extracted mainly from species belonging to Gigartinales. These sulfated galactans, consist of linear chains of D-galactopyranoses linked in a (1 & 3) and b (1 & 4). Seaweeds constitute some of the most important reservoirs of new therapeutic compounds for humans. Several of them have been shown to have many biological activities, including anticancer activity, in this present review study is mainly focused on Hypnea valentiae.
