Volatile Constituents ofAloysia triphylla(L'Herit.) Britton

Pharmacological and neuroprotective profile of an essential oil derived from leaves of A loysia citrodora Palau

“…In our study, α‐pinene, α‐terpinene, sabinene, linalool and caryophyllene were also identified in low amounts. However, our results did not show the presence of carvacrol, camphor and thymol, which have been mentioned in other studies regarding A. citrodora [31,35]. These monoterpenoids have previously been reported as some of the main constituents of EOs from A. citrodora from different parts of the world [18,19,24–27].…”

“…All other components remained more or less unchanged both qualitatively and quantitatively. According to the literature, limonene is the component found to occur in highest quantities in EOs of the genus Lippia , followed by p‐cymene, α‐pinene, camphor, β‐caryophyllene, linalool and thymol in a decreasing order [18,19,24–34]. In our study, α‐pinene, α‐terpinene, sabinene, linalool and caryophyllene were also identified in low amounts.…”

“…The monoterpenoids limonene, geranial, neral and 1,8‐cineole have previously been reported as some of the main constituents of EOs from A. citrodora (including EOs documented from species described as synonyms for A. citrodora [14,24–27]. It is essential to characterise EOs investigated pharmacologically, as oil composition from a particular species may vary considerably due to various factors, including genetic and environment influences [28–34]…”

“…In spite of its wide use and the regulations for cultivation, until now there were no studies about its pharmacological properties except some reports about antimicrobial activity of the essential oil and depressant effect of the leaves infusion (Alonso and Desmarchelier, 2005). A little is known about its active principles, except the presence of a flavonoid, luteolin-7-diglucuronide (Skaltsa and Shammas, 1988;Carnat et al, 1995), the phenolic compound verbascoside and the composition of the essential oil (Zygadlo et al, 1994;Carnat et al, 1999;Alonso and Desmarchelier, 2005).…”
