Ethanol extracts of parsley (Petroselinum crispum) and fennel (Foeniculum vulgare) leaves contain a broad range of biologically active phytochemicals. Qualitative screening demonstrates the presence of flavonoids, tannins, saponins, steroids, terpenoids, alkaloids, and glycosides across both botanical species. Gas chromatography-mass spectrometry profiling of the fennel extract detects two bioactive compounds, specifically 1,4-cyclohexadiene and metronidazole. The parsley extract yields six identifiable bioactive constituents, including cineole, l-limonene, cyclohexane, phenol, neophytadiene, and 9,12,15-octadecatrienoic acid. Fourier-transform infrared spectroscopy provides further characterisation of functional groups within the extracts. Parsley displays spectral bands corresponding to carbon-hydrogen stretching and nitrogen-hydrogen stretching vibrations associated with amino acids. Fennel exhibits absorption bands indicative of carbon-hydrogen stretching in alkenes and alkanes, alongside carbon-oxygen stretching bands characteristic of esters.
Identifying the natural chemical constituents of common culinary and aromatic herbs helps map their biological profiles. Parsley and fennel contain numerous bioactive molecules and diverse chemical groups that are of interest across natural products research. Establishing which compounds are successfully recovered through ethanol extraction provides foundational chemical data regarding the specific constituents present in the foliage of both plants.

The species Petroselinum crispum (Parsley) and Foeniculum vulgare (Fennel) are aromatic herbs belonging to the Apiaceae and Lamiaceae family respectively. The leaves of both plants were consecutively extracted based on separation using ethanol and subjected to phytochemical testing that revealed the presence of biologically active compounds such as flavonoids, tannins, saponins, steroids, terpenoids, alkaloids and glycosides. The GC- MS evaluation of Foeniculum vulgare revealed two bioactive compounds (1,4 Cyclohexadiene and Metronidazole) and Petroselinum crispum revealed six bioactive compounds (Cineole, I-Limonene, Cyclohexane, Phenol, Neophytadiene and 9,12,15 octadecatrienoic). In the FTIR analysis, the Petroselinum crispum displayed strong bands at 2915.50 cm-1 which corresponds to C–H stretching and medium band at 1476.80 cm–1 which corresponds to N-H stretching vibrations due to the presence of amino acids. The Foeniculum Vulgare displayed strong bands at 2832.61 cm-1 which corresponds to C–H present in alkenes and alkanes respectively, and medium band at 1029.98 cm-1 corresponds to C–O present in esters.
