Studies on Phytochemical Screening and in- vitro anti-inflammatory activity of Delonix elata L. leaves

Inflammatory diseases including arthritis and rheumatism are major group of prevalent diseases. Inflammation is the complex biological response of vascular tissues to harmful stimuli including pathogens, irritants or damaged cells. Many substances, interfering with the inflammatory response have been isolated from medicinal plants. Natural products with anti inflammatory activity mainly contain active principles viz, flavonoids, terpenoids, steroids, Phenolic compounds, saponins and alkaloids. The aim of this study is to investigate the Phytochemical constituents and evaluated for possible anti-inflammatory activity of leaves of Delonix elata by human red blood cell (HRBC) membrane stabilization method. The extract of leaves of D. elata contains terpenoids, flavanoids, steroids, phenols, cardioglycosides, quinines, coumarins and tannins. The ethanolic extract of leaves of D.elata is evaluated for anti-inflammatory activity by human red blood cell (HRBC) membrane stabilization method and their activities are comparable to that of the standard drug Aspirin.
