|
Ethyl esters (EEs) are the most abundant compounds in virgin coconut oil (VCO). The enfleurage of Cymbopogon nardus leaves as a potential antioxidant in VCO could improve its profile and characteristics. This study aimed to separate the EE compounds and determine the profile of VCO with the enfleurage of C. nardus leaves in the mixture. The sample was prepared via enfleurage and the EE compounds were analysed using gas chromatography–mass spectrometry (GCMS) and Fourier transform infrared spectroscopy (FTIR). The profile of the EE compounds consisted of tetradecanoic acid (ethyl myristate); octanoic acid (ethyl caprylate), with 1.5 resolution and m/z 88 and tetradecanoic acid, which increased by 20% in the VCO with enfleurage of C. nardus leaves at a ratio of 100:1 g. Less than 2% of ethyl laurate and 7% of ethyl palmitate in the extracts were evaporated using a vacuum evaporator. Results showed a similarity in the FTIR spectrogram with detected carbonyl functional groups but with a decreased percentage of transmittance.
