Comparative FT-IR analysis of chloroform fractions of leaf extracts of Anacardium occidentale, Psidium guajava and Terminalia catappa

Abstract

The present study identified and characterized phytocomponents from chloroform fractions of leaf extracts of Anacardium occidentale, Psidium guajava and Terminalia catappa. The identification and characterization of phytocomponents from chloroform fractions of leaf extracts of A. occidentale, P. guajava and T. catappa were carried out using FT-IR system protocol. The weak bands around 2922.2 cm-1 and 1714.5 cm-1 were indicative of the presence of carboxylic acids, whereas the presence of ethers was represented by relatively medium bands around 1088.4 cm-1 and 1047.4 cm-1 in chloroform fraction of leaf extract of A. occidentale. Likewise, chloroform fraction of leaf extract of P. guajava contained ethers (1088.4 cm-1 and 1047.4 cm-1), esters and phenolics (1267.3 cm-1). Notable phytocomponents in chloroform fraction of leaf extract of T. catappa were ethers (1088.4 cm-1 and 1047.4 cm-1) and nitro compounds (1379.1 cm-1 and 1323.2 cm-1). A general outlook of the present study revealed peculiarities in phytocomponent profiles of chloroform fractions of the leaf extracts, which depended on the polarity of the fractionation solvent and plant species variations.
