found in one of the oils of the aerial parts in low percentage (0.4%), while the santolina triene (**Figure 9**) was not found in any of the oils of the aerial parts. As in the oil of aerial parts, sesquiterpenoids predominated in the root oil. Since the plant has been used in the past for the treatment of stomach pain, the authors consider it of value to carry out pharmacological activity tests with this oil in the

It was found in this study that the essential oil of aerial parts of wild *S. serrata* from different populations of the highlands of Guatemala showed high concentrations of chamazulene. In addition, the essential oil of roots of the plant was analyzed for the first time, which presented a composition very different from that of the aerial parts, as it did not present chamazulene and presented α-longipinene as the major component. It was also verified that the seeds of *S. serrata* present a high viability and that the seedlings obtained from seeds also have a high percentage of survival. Therefore, *S. serrata* can be considered as a plant with high potential for domestication and cultivation for the production of essential oil with high content
