Comparative analysis of the aroma chemicals of Mentha piperita L. using hydrodistillation and CombiPAL system techniques
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 2
Abstract
Aerial parts of Mentha piperita L. (Peppermint) were subjected to headspace and hydrodistillation techniques after drying, then headspace volatiles and the essential oil were analyzed by GC/MS. 50 and 40 constituents were identified in hydro-distillation and CombiPAL system which represented 100% and 100% of the oils, respectively. Hydro-distillation method were β- pinene (1.29%), limonene (3.11%), 1,8-cineole (6.30%), cis- sabinene hydrate (1.85%), menthone (34.86%), isomenthone (7.99%), mentofuran (5.11%), menthol (23.98), pulegone (1.99%), menthyl acetate ( 1.70 %), (E)- caryophyllene (1.95%), germacrene D (2.20%) and the main compounds by Headspace techniques were α-pinene (8.06%), β- pinene (7.67%), myrcene (2.24%), limonene (13.36%), sabinene(5.03%),1,8- cineole (17.85%), (Z)-β-ocimene (1.84%), cis-sabinene hydrate (1.49%), menthone (18.75%), isomenthone (4.63%), mentofuran (3.98%) and menthol (9.28). The Headspace Technique is a new, rapid, simple and eco-friendly method for essential oil analysis of aromatic plants.
