The main purpose of this study was to screen for the presence of phytochemicals by UV, FT-IR and GC-MS analysis of the methanol extract of the plant Tabebuia rosea (Family Bignoniacae. the Wavelengths and individual peaks up to 200–800 nm were observed using methods (Shimadzu UVd-1800 PC, Japan). FTIR analysis was achieved using the Berkin Elmer spectrophotometer method, the GC-MS analysis of the plant area using the Berkin-Elmer GC Clarus 500 system and the interpretation of the mass spectrum GC-MS using the National Institutional Standards and Technology (NIST) database. The results showed a peak associated with phenolic compounds in the UV spectrum at 750.3 nm. The FT-IR spectrum of plants, alcohols, phenols (3367.74, O - H Stretch, H - Bonded), GCMS chemical complexes are linked from plant extracts, indicating the presence of functional groups with associated vibration frequency (cm.). RT15.534 and 192 show the key components at the apex. Other most prevailing phyto-constituents are Phenol,-bis(-dimethylethyl), Hexadecanoic Acid, Methyl Ester, Tetradecanoic Acid, Octadecanoic Acid Ethyl Ester, N-Octade Stearic Acid, Hexadecanoic Acid, Palmitic Acid Butyl Ester, Oleic Acid, (Z)-9-Butyl Ester Octadecenoic, N-Propyl-Octadecatrienoate N-Propy, Octadecanoic Acid, Butyl Esteretc., which are equivalent to gallic acid, rutin, kaempforol and quercetin, individually. The phenolic emulsion and O-H functional group. The presence of countless bioactive composites validates the use of Tabebuia rosea for various faults by traditional high priests.
