This plant has several beneficial properties. The powder leaves of Corydyline terminalis L. Kunth was extracted with organic solvent such as hexane, ethyl acetate, chloroform, butanol and methanol. The total phenolic contents of the extracts was determined by Willet method with modification. The results for total flavonoids content of the extracts as caffeic acid equivalents were found to be highest in hexane extract (68.02%) followed by ethyl acetate (61.50%), methanol (39.27%), butanol (19.08%) and chloroform (15.75%). Based on these results it can be suggested that the biochemical properties of the leaves for curing various ailments.
