A phytochemical investigation of Dodonaea viscosa plant extract was conducted. A new 3,5,7-trihydroxy-6,4′-dimethoxy-3′-isoprenyl-flavone (1) and three known compounds Hautriwaic lactone (2), Kamempferol 3-methyl ether (3) and vanillic acid (4) were isolated from the aerial parts of Dodonaea viscosa. The structure of the isolated constituents was elucidated using 1D and 2D Nuclear Magnetic Resonance (NMR) and mass spectrometry. The qualitative study of the Fraction 1 was performed by using Gas Chromatography (GC) and Gas Chromatography – Mass Spectrometry (GC-MS). The nature of compounds was confirmed by NIST library search. The antimicrobial activity and possible use of the plant extracts were also elaborated.
