Phytochemical Screening and Spectroscopic Characterization of Parkia biglobosa Stem Bark: A Potential Source of Medicinal Compounds.

This article focuses on the phytochemical screening and spectroscopic characterization of Parkia biglobosa stem bark to evaluate its potential as a source of medicinal compounds. The study employed qualitative and quantitative phytochemical analyses, Fourier-transform infrared (FT-IR) spectroscopy, and Gas Chromatography-Mass Spectrometry (GC-MS) on methanol extracts of the bark collected in Kano State, Nigeria. Results revealed the presence of bioactive compounds including alkaloids, flavonoids, tannins, phenolics, saponins, terpenoids, and cardiac glycosides, with tannins being the most abundant. FT-IR identified functional groups consistent with phenols and terpenoids, while GC-MS detected compounds such as 5-chlorovaleric acid and propenamide, supporting the plant’s traditional use for treating oxidative stress, inflammation, and cardiovascular diseases. The findings validate the therapeutic potential of P. biglobosa stem bark and suggest further pharmacological studies to isolate and evaluate its bioactive constituents.
