Volatile composition of the critically endangered plant <em>Thymus webbianus</em> Rouy from the Natural Park “Penyal d’Ifach” (Calp, Spain)

Abstract

Thymus webbianus Rouy (Lamiaceae) is an endemic plant known from only two populations located in theNatural Park "Penyal d 'Ifac" (Calp), and in the Natural Park of Serra Gelada (Benidorm-Alfàs del Pi) in Spain. At the Spanish state level, it has been listed as "Critically Endangered", and "Vulnerable" in the Valencian Region. Moreover, its taxonomic position remains unclear, and further research on this species is needed. Therefore, this work was aimed to characterize the chemical composition in volatiles from four subpopulations located in the Natural Park "Penyal d'Ifach" through HS-SPME-GC-MS.
