Chemical comparison of the essential oils of Lippia Origanoides in two agroclimatic zones of the Colombian Caribbean coast

The objective of this research is to compare the chemical profiles essential oils Lippia origanoides leaves collected in Santa Marta and Sincelejo at different hours. were harvested 6:00 a.m., 12:00 p.m, extracted by hydrodistillation assisted microwave radiation determined gas chromatography coupled mass spectrometry. results showed Thymol as major metabolite all samples, however, presented highest percentages with 68.02% while p.m was 63.19%. In cases, lowest concentrations found md, because high temperatures can volatilize compound case Marta, it a coastal area temperature noon higher than Sincelejo. Therefore, 33.12% 59.06% respectively. A similar occurs Ocimeno 3-Tujeno, which decrease concentration period.
