### GC/MS Analysis  
The chromatographic analysis via liquid injection showed no significant differences among the samples. Some compounds detected in the less polar fractions (such as the hexane partition) were also present, albeit in smaller quantities, in the crude extract and the other fractions, with variations in their proportions. Therefore, the results presented in Table 5 pertain to the SPME analysis of the crude extract, fractions, and fresh leaf samples (Figures S3 and S7). The 25 substances detected correspond to the major peaks and include alcohols, aldehydes, ketones, acids, fatty acid esters, terpene derivatives, among others. \begin{table}
