Variations in the headspace volatile profiles of three different Achillea coarctata Poir. (Asteraceae) populations
This study presents a detailed compositional analysis of six Achillea coarctata Poir. samples obtained by static
headspace method and interrelationships based on the volatiles profiles from different plant parts, three
different populations and geological substrates, using multivariate statistical analysis. The most dominant
components were mutual for aerial vegetative plant parts and inflorescences collected at the same locality.
Main compounds differed in percentages for two localities (values in parenthesis refer to aerial plant parts and
inflorescences, respectively): 1) 1,8-cineole (40.7%; 39.9%), β-pinene (29.6%; 36.4%) and α-pinene (7.2%;
3.3%); 2) 1,8-cineole (51.8%; 53.3%), β-pinene (18.0%; 28.2%) and α-pinene (5.6%; 4.5%). the most abundant
constituents identified in third locality were 1,8-cineole (37.2%; 35.6%), β-pinene (18.6%; 11.7%) and ocymene
(11.6%; 11,7%). Samples collected on different geological substrates are qualitative and quantitative
various according to agglomerative hierarchical clustering analysis and can be grouped in two clades and two
subclades
