Plants and fruits are considered as one of the main sources of biologically active compounds, and several studies reported that medicinal plants are used by 80% of the people living in rural areas as primary healthcare system. Morinda citrifolia has been heavily promoted for a wide range of uses, including antibacterial, antiinflamatory, analgesic, antioxidant, and antitumor effects. The objective was to identify chemical constituents in leaves extract and fruit juice of Morinda citrifolia by GC-MS analysis. The bioactive constituents in ethanolic extract leave and fruit juice of Morinda citrifolia were investigated using Gas Chromatography-Mass Spectrometry GC-MS analysis. Bioactive constituents studies of ethanolic extract leaves and fruit juice of M. citrifolia by GC-MS analysis clearly showed the presence of eighteen and fifteen compounds, respectively. Among the identified compounds of medical importance were detected (octanoic acid, cyclopropyl, hexanoic acid, n-decanoic acid, allantoin, sorbitol, mannitol, glycerin and gamma-tocopherol).
