Chemical composition of olive stems essential oil from Ethiopia
Main Article Content
Abstract
In this article, the chemical compounds, antimicrobial and antioxidant activity of the volatile oil from leaves of Olea Europaea L. cultivar from Ethiopia has been studied. The essential oil was provided with a dry distillation apparatus and analyzed by GC-MS/FID. This analysis leads to the detection of 128 compounds representing 89.4% of the total oil. The major constituents were methyl ester hexadecanoic acid (4.10%), 2,4-dimethoxyphenolAa (4.05%), 2-methoxy-phenol (3.25%), 3,5-dimethoxy-4-hydroxytoluene (3.20%), 2-methoxy-5-methyl phenol (3.19%), 1,2,3-trimethoxy-5-methyl benzene (2.93%), 2-methoxy-4-vinyl phenol (2.70%), 2-hydroxy-3-methyl-2-cyclopenten-1-one (2.60%), trans-Isoeugenol (2.45%) and (E) -2,6-dimethoxy-4- (prop-1-en-1-yl) phenol (2.25%). The composition of essential oils was dominated by phenolic compounds.
