Abstract
T. ornata a macroalgae rich in bioactive molecules possess various biological activities. Herein, the aim of the study is to evaluate the aqueous extract and the sulphated polysaccharide isolated from T. ornata for its anti-arthritic potential in Complete Freund’s Adjuvant (CFA) induced arthritis in rats. Anti-arthritic potential of aqueous T. ornata (ATO) and T. ornata sulphated polysaccharide (TSP) was evidenced by the significant reduction in paw volume and arthritic score. Inflammatory and antioxidant markers were found to be restored in the drug treated groups which was found to be in line with dexamethasone a standard anti-inflammatory drug. The histopathological and radiological examination adds on the support to the above findings confirming the anti-arthritic potential of ATO and TSP. It is interesting to note that the sulphated polysaccharide inhibits inflammation and bone damage at very low dose itself. Hence, TSP could be considered as a better candidate in the management of chronic inflammatory diseases like rheumatoid arthritis.
