Abstract

ABSTRACT . The chemical composition of the essential oils obtained by hydrodistillation from Cupressus arizonica Greene, Juniperus communis L. and Mentha longifolia L. were determined by gas chromatography-mass spectrometry (GC/MS) analysis. The chemical composition of the essential oils were identified by GC/MS. Eicosane (27.4%), umbellulone (13%) and α-pinene (10.51%) were the major components of C. arizonica oil; sabinene (32%), limonene (26%) and bornyl acetate (7.4%) were the major components of J. communis oil and pulegone (26%), L -menthone (13.4%) and cis -para-menthan-3,8-diol (10.2%) were the major components of M. longifolia oil. The percentage of monoterpenes in the three essential oils was compared. The percentage of monoterpenes in C.arizonica is about 5.2%, J. communis 46%, and M. longifolia is 50.1%. The percentage of terpenes in C. Arizonica (16.3%), J. communis (5.2%) and M. longifolia (9.3%) were reported. But the percentage of cyclic monoterpenes in C. arizonica is about 6%, J. communis 26.1%, and M. longifolia is 3%. Monoterpenes are the most components that make up essential oils.

Highlights

Essential oils have been of the supreme importance for fine pharmacology applications, aroma and cosmetic preparations for a long time, because of their intense, pleasant, sweet, and floral as well as their fixative properties [1,2,3,4]
The chemical composition of the essential oils obtained from J. communis have 25 compounds, the major of them include sabinene (C10H16): (32%), limonene (C10H16): (26%) and bornyl acetate (C12H20O2): (7.4%)
The chemical composition of the essential oils obtained from M. longifolia have 29 compounds, the major of them include pulegone (C10H16O) (26%), L-menthone (C10H18O): (13.4%) and cis-p-menthan-3,8-diol (C10H20O2): (10.2%) (Table 3)

Summary

Introduction

Essential oils have been of the supreme importance for fine pharmacology applications, aroma and cosmetic preparations for a long time, because of their intense, pleasant, sweet, and floral as well as their fixative properties [1,2,3,4]. Main identified compounds of the C. arizonica, J. communis and M. longifolia essential oil in several studies obtained by GC/MS showed that α-pinene was the main components of the essential oil leaves of C. The chemical composition of the essential oils obtained from J. communis have 25 compounds, the major of them include sabinene (C10H16): (32%), limonene (C10H16): (26%) and bornyl acetate (C12H20O2): (7.4%)
