Chemical composition of essential oils isolated from Mexican giant hyssop [Agastache mexicana (Kunth.) Link. & Epling.] via hydrodistillation in Deryng and Clevenger apparatuses

Abstract

Flowering herb of Agastache mexicana (Kunth.) Link. & Epling. was collected, dried in natural conditions and distilled in order to extract the essential oils. The extraction method involved hydrodistillation in either Deryng or Clevenger apparatus. The extracted oils were subjected to GC-MS analysis. The most abundant compounds identified in the extracts were pulegone (47.77–49.48%), limonene (15.45–15.93%) and cis-menthone (12.25–12.89%). The study showed that the distillation method did not significantly affect either qualitative or quantitative composition of the essential oil of Agastache mexicana (Kunth.) Link. & Epling.
