Composition of essential oil of <i>Stachys alpina</i> L. ssp. <i>dinarica</i> Murb.

Abstract

Abstract Essential oils of aerial parts of Stachys alpina ssp. dinarica collected from two localities in Bosnia and Herzegovina (Mt Jahorina and Mt Maglic, respectively) were investigated. Essential oils were obtained by hydrodistilation and analyzed using GC and GC‐MS. Essential oil yields were 0.03 and 0.05% (w/w), respectively, and in each oil 71 components were identified, comprising 87.2 and 89.3% of the total amount. The main components in both samples were ( E )‐caryophyllene (13.4 and 9.3%), germacrene D (12.3 and 5.5%), caryophyllene oxide (5.7 and 8.4%), ( E )‐nerolidol (4.8 and 5.6%), n ‐nonanal (5.3 and 5.0%) and linalool (1.7 and 5.7%, respectively).
