Phytochemical, GC-MS, FTIR and Amino acid profile of methanol extract of Tetrapleura tetraptera fruit

Abstract

The methanolic fruit extract of Tetrapleura tetraptera was analyzed for the presence of phytocompounds, their bioactivity, the functional groups involved in this activity, and its amino acid profile using standard procedures. Phytochemicals such as tannins, phenols, flavonoids, and alkaloids were identified as being highly present. Gas chromatographic-mass spectrometric (GC-MS) analysis identified 16 bioactive compounds, with 2-thiopheneethanol (58.77%) being the most abundant. Curcumin, with the most diverse pharmacological role, and other bioactive compounds such as cedren-13-ol, 8 (1.56%), N-benzyl stearamide (4.46%), a prominent fatty acid amide hydrolase (FAAH) inhibitor; pthalic acid, butyl undecyl ester (1.49%); and phenol, 2, 6-bis (1,1 dimethyl ethyl) (1.46%), were also present. Fourier transform infrared (FTIR) analysis confirmed the presence of alkanes, esters, benzene rings, aliphatic, sulfonic acid, and methylene chains. Also, the amino acid analysis of the T. tetraptera revealed that the fruit contains 18 amino acids. Leucine (4.20%), phenylalanine (3.37%), and valine (3.25%) were the most abundant essential amino acids identified, with glutamic (7.20%) and aspartic acid (5.61%) having the highest concentrations as non-essential amino acids. This therefore indicates that T. tetraptera fruit could be used as a pharmacological or therapeutic agent as well as a dietary condiment, particularly at this time when there is a demand for novel protein sources.
