Analysis of Tabebuia rosea oil and Tabebuia rosea oil methyl esters using Fourier transform infrared (FTIR) spectroscopy

Abstract

Fourier transform infrared (FTIR) spectroscopy method was used for the analysis of phytochemicals present in Tabebuia rosea seed oil and its biodiesel. FT-IR spectra of Tabebuia rosea seed oil and its biodiesel have been recorded in the region 2925 - 604 Cm-1. FT-IR is a vibrational spectroscopy that records absorptions of IR light by chemical bonds in all molecules including polymers. The different frequency ranges and their different functional groups were analyzed during the study period. FT-IR spectroscopy of the Tabebuia rosea seed oil reveals diverse functional groups and there by confirmed the possible presence of phytochemicals such as Terpenoids, Steriods, Flavonoids, Tannins, Coumarins, etc.
