Studying the origin of 1,8-cineole, the Australian Wine Research Institute (AWRI) found that the location and leaves of eucalyptus trees play a direct role in the concentration of 1,8-cineole and occurrence of the "eucalypt," "fresh" or "minty" characters in wine.
The major components were as follows: [beta]-cymene (8.64%), [gamma]-terpinene (9.43%), thymol (38.53%), and carvacrol (10.11%) in TV1; [beta]-cymene (16.53%), [gamma]-terpinene (22.19%), and thymol (37.89%) in TS; [alpha]-pinene (14.06%), [beta]-cymene (10.29%), D-limonene (11.72%), thymol (11.01%), and 1,8-cineole (20.02%) in TV2.

microphylla is probably related to the presence of the monoterpenes [beta]-ocimene (15.20%) and 1,8-cineole (18.12%), which are compounds that have antimicrobial activity and synergism with the other constituents.
Its antimicrobial activity against several microorganisms has been recognised for decades and has been attributed to the presence of some major compounds in essential oils like 1,8-cineole, [beta]-thujone, camphor, borneol and [beta]-cymene, among others.
The essential oil composition of Eucalyptus globulus obtained of this study, showed a relatively similar pattern to those published for other geographical regions: 1,8-cineole (84.7%), [alpha]-pinene (4.4%), transpinocarveol (2.2%), were reported as the major component in the essential oil of Eucalyptus viridis and 1 ,8-cineole (89.4%), [beta]-pinene (1.2%) and [alpha]-pinene (1%) of Eucalyptus oleosa from Iran (Jaimand et al, 2009), oxygenated monoterpene: 1 ,8-Cineole (69.53%) and the monoterpene hydrocarbon: [alpha]-pinene (11.94%) from Tunisia (Bendaoud et al, 2009).
1,8-cineole (85.5%) was reported to be the major constituents in E.
The interaction of a potent percutaneous penetration enhancer, 1,8-cineole, with the stratum corneum (SC) and DPPC membranes was investigated by electron paramagnetic resonance spectroscopy (EPR) of spin-labeled analogs of stearic acid (5DSA) and androstanol (ASL).
The chief components of oil include menthol (30(35)-55%), menthone (14-20(32)%), 1,8-cineole (6-8(14)%), isomenthone (2-3(10)%), menthyl acetate (3-5%), neomenthol (2.5-3.5%), menthofurane (1(2)-7(9)%), limonene (1-5%), etc.
Approximately 12% of 1,8-cineole, 5% linalool, and 4% [alpha]-terpineol have also been reported in fennel oil (Mansour et al., 2011).
