Morinda citrifolia L. has been used for the treatment of such diseases as gastritis, dermatitis, respiratory infections, menstrual and urinary disorders, fever and diabetes. This study aims to identify the phytochemical constituents of the ethanolic extracts of Morinda citrifolia L. and to record its profile based on Thin Layer Chromatography (TLC). The phytochemical analysis of the ethanolic extracts of Morinda citrifolia L. indicated that the roots contained phenols, coumarins, cardiac glycosides and steroids. The fruits possessed alkaloids, phenols, tannins, coumarins, cardiac glycosides and steroids. The leaves consisted of alkaloids, saponins, phenols, tannins and coumarins. Their layouts of TLC analysis investigated under 254-366 nm UV light gave good separation with the mobile phase system  
of chloroform:methanol (7:3). These reveal authentication for the quality control of Morinda citrifolia L. and exhibit significant role in the fields of drug isolation and medicinal chemistry.
