Résumé : |
The chemical composition of the essential oil from flowering tops of Achillea millefolium L. isolated by different distillation methods was studied.
Samples were hydrodistilled with Clevenger-type (HD), simultaneous microdistillation-extraction (SMDE), and microwave (MAHD) apparatus.
The yields were 0.46% ± 0.03 for the HD and 0.48% ± 0.03 for the MAHD (v/w, volume/dry weight).
The oils were analyzed by GC and GC/MS and a total of 58 components were detected.
The major compounds in the oils were 1,8-cineole (10.4–17.2%), sabinene (11.6–14.6%), α-terpineol (4.4–5.2%), terpinen-4-ol (2.4–5.7%), and, among sesquiterpenes, γ-eudesmol (8.7–17.9%) and 6S,7Rbisabolone (4.4–14.9%).
From a qualitative point of view, no relevant differences between the different methods of isolation were observed, while statistically significant differences on relative percentage were noticed.
Oils obtained by HD showed a higher amount of monoterpenoid compounds (69.2%), while L-SMDE, H-SMDE and MAHD were richer in sesquiterpenes (47.9%, 42.7% and 47.6%, respectively). |
