Medicinal plants are potential sources of natural compounds with biological activities and therefore attract the attention of researchers worldwide. The objective of this research was to determine the chemical composition of seeds extract from methanol. The phytochemical compound screened by gas chromatography - mass spectrometry (GC-MS) method. Fifty six bioactive phytochemical compounds were identified in the methanolic extract of Foeniculum vulgare. The identification of phytochemical compounds is based on the peak area, retention time molecular weight, molecular formula, MS Fragmentions and Pharmacological actions. The Fourier transform infrared spectroscopy (FTIR) analysis of F. vulgare seeds proved the presence of alkenes, aliphatic fluoro compounds, alcohols, ethers, carboxlic acids, esters, nitro compounds, alkanes, hydrogen bonded alcohols and phenols.
