Abstract :

The present study was designed to investigate the phytochemical screening using FT–IR analyses for the qualitative identification of bioactive compounds in Alternanthera sessilis (L.) Trigonella foenum–graecum (L.) leaves extract. The qualitative FT–IR spectrum profile of ethanolic extract of Alternanthera ssesilis (L.) showed the peaks at 3294.42/ cm–1, 2918.30 cm–1, 2850.79/ cm–1, 2362.80/ cm–1, 1737.86/ cm–1, 1624.06/ cm–1. The FT–IR spectra analyses of Trigonella foenum–graecum (L.) confirmed the presence of different functional groups with a peak value of 537.11 cm–1, 622.50 cm–1, 834.43cm–1, 1063.64 cm–1, 1102.83 cm–1,243.14 cm–1, 1385.24 cm–1, 1423.53 cm–1, 1649.17cm–1,1736.40 cm–1, 2144.79cm–1, 2852.51 cm–1, 2921.41 cm–1 and 3356.40 cm–1 in the ethanolic extract of leaves. These peak values confirmed the presence of characteristic functional groups of alkyl halides, alkynes, aromatics aliphatic amine, aromatic amines, amines, aromatics, nitriles, alkenes, alcohols and phenols in the leaf extract. They could be responsible for the various medicinal properties of Alternanthera ssesilis (L.) and Trigonella foenum–graecum (L.). The presence of various bioactive compounds justifies the use of the leaves for various ailments by traditional practitioners. The result of this study offer a platform of using Alternanthera ssesilis (L.) and Trigonella foenum–graecum (L.) leaves as herbal alternative for various diseases.
