FOURIER TRANSFORM-INFRA RED (FT-IR) SPECTROSCOPIC CHARACTERIZATION OF THE ESTERS OF ABRUS PRECATORIUS LEAVES

Esters because of their importance in the chemical industry have received great attention. In this study, esters from the leaves of Abrus precatorius were extracted using petroleum ether, chloroform, methanol and mixture of these solvents in different ratios. The extracts after fractionation using column chromatography were qualitatively identified with Fourier-transform infra-red (FTIR) spectroscopy. 1,2,3—trisubstituted alkane had the highest intensity in all the extract with exception of the extract obtained from chloroform:methanol (50:50) which had halo-compound as the most intense compound. The extracts also had carboxylic acid, secondary alcohol, carbodiimide, sulfonamide, alky ester, and alkene with varying intensity. The leaves of A. precatorius contained esters and other bioactives that could find use in pharmaceutical and other chemical industries.
