Abstract
Objective: Aframomum melegueta Schum (Zingiberaceae) is widely cultivated for its valuable seeds in the tropical region of Africa. This study identified the bioactive components present in aqueous seed extract of Aframomum melengueta Methodology: Aqueous seed extract of Aframomum melengueta was qualitatively and quantitatively analyzed using Fourier-transform infrared spectroscopy (FTIR) and Gas chromatography coupled with flame ionization detector (GCFID). Result: FTIR identified twelve organic functional groups of –OH, -NH2, CH, -NH3+, -CH3, -OH, -N=C=O, -C≡N, -C=C=C, -NH, -CH3 and -1,3,5-trisubstituted benzenes. GCFID identified fifteen bioactive components namely kaemferol, naringenin, sapogernin, flavanones, anthocyanin, flavan-3-ol, cyanogenic glycoside, ribalinidine, rutin, catechin, resveratol, spartein, epicatechin, steroid and phytate. Conclusion: The highest concentration of bioactive components was sapogernin 23.1038µg/ml, while the lowest concentration 1.0565µg/ml consisted of Naringenin.
