### Obtention and Characterization of Essential Oils  
During sample processing by hydrodistillation, characteristic behaviors of each essential oil were observed, namely the striking color of the distillation water for EOT1 and the absence of this in EOT2. On the other hand, oil drops were visible only in EOT2. The yield of the essential oils EOT1 and EOT2 was 0.19% and 0.9%, respectively. For EOT1, 61 compounds were identified, which corresponds to 93.70%; meanwhile, 87 compounds, which represented 92.98% of the total were identified in EOT2. In both oils, the major component was 1-pentadecene, comprising 77.6% and 57.9% of the total in EOT1 and EOT2, respectively, followed by 1-tridecene (3%), limonene (2.9%), pentacosane (1.8), and tricosane (1.5%), in EOT1, while hentriacontane (6.53%), palmitic acid (6.47%), linoleic acid (2.79%), tricosane (2.79%), pentacosane (2.2%), 1-tridecene (1.75%), oleic acid (1.72%) and limonene (1.43%) were the most abundant compounds in EOT2 (Table 3, Figures S5 and S6). \begin{table}
