Lippia origanoides chemotype differentiation based on essential oil GC‐MS and principal component analysis

Abstract: Chromatographic (GC/flame ionization detection, GC/MS) and statistical analyses were applied to the study of essential oils and extracts obtained from flowers, leaves, and stems of Lippia origanoides plants, growing wild in different Colombian regions. Retention indices, mass spectra, and standard substances were used in the identification of 139 substances detected in these essential oils and extracts. Principal component analysis allowed L. origanoides classification into three chemotypes, characterized acco… Show more

“…However, in this study, thymol and carvacrol were not found, while pcymene was detected in small quantities. These findings are in accordance with the information reported by Rodrigues et al (2011) andStashenko et al (2010), who demonstrated very divergent chemical profiles in this species. The wide variety of chemotypes found in L. origanoides may be a factor of the synonymization proposed by O' Leary et al (2012); in a revision of the Goniostachyum section of Lippia, the authors synonymized 41 species into only four.…”

“…El Análisis de Componentes Principales (PCA), junto con la información detallada de la composición del aceite, constituyen una herramienta base para la clasificación de quimiotipos [51]. Mientras que los aceites esenciales de los quimiotipos de Lippia origanoides "Timol" y "Carvacrol" presentan una alta actividad antioxidante [24], el aceite esencial aislado del quimiotipo "Felandreno", no exhibe…”
