“…All other components were found to be in low quantities (B2%; Table 1). Our findings are parallel to earlier findings depicting presence of a-pinene and 1,8-cineole as major constituents of essential oils from E. tereticornis (Pino et al 2001;Cimanga et al 2002;Ogunwande et al 2003;Singh et al 2009). …”

The present study investigated the chemical composition and allelopathic potential of volatile oil from Eucalyptus tereticornis on growth and establishment of Amaranthus viridis, a wasteland weed. The volatile oil was rich in monoterpenoids and a total of 34 components were identified by gas chromatography/gas chromatographyÁmass spectroscopy analyses, constituting 98.52%. a-Pinene (32.5%) and 1,8-cineole (22.4%) were the two major constituents. The volatile oil and two major components were evaluated for their allelopathic potential against A. viridis. A significant reduction in early seedling growth and seedling vigor of A. viridis was observed in response to volatile oil or its major monoterpenes. Further, the contents of photosynthetic pigments, i.e. chlorophylls a and b, and carotenoids, and cellular respiration in oil-/monoterpene-treated seedlings were significantly reduced thereby indicating adverse effects of the oil on photosynthetic machinery and energy metabolism. Based on the study, it can be concluded volatile oil of E. tereticornis possess allelopathic potential and could be explored as bioherbicide for future weed management programs.

“…Elassi et al (7) showed that the major compounds present in the essential oils of 10 Eucalyptus species had expected similarities because they were obtained from plants belonging to the same genus, followed by a-pinene, p-cymene, borneol, cryptone, spathulenol, viridifl orol and limonene. Ogunwande et al (22) showed that β-pinene (39.4%) and α-pinene (30.4%) were the dominant constituents in oil samples obtained from E. tereticornis Smith and Eucalyptus grandis W. Hill, respectively, with no detectable 1.8-cineole. 1,8-cineole, the predominant compound observed in the present study, has relatively strong antimicrobial properties against many important pathogens (5) (8) (30) , besides low toxicity observed in in vitro tests (13) .…”

“…The Marocco oil was found to contain p-cymene (23%, 2%), 1,8-cineole (20%, 43%) and α-pinene (14%, 74%) [13]. The Nigerian E. grandis oil contained a-pinene (30%, 4%), terpinen-4-ol (10%, 7%), E-β-ocimene (9%, 4%), borneol (8%, 4%) and α-terpineol (8.0%) [1]. The major components of E. grandis and E. urophylla oils from Ethiopia were respectively α-pinene (44%, 7%), α-pinene (30%, 5%) and, limonene (9%, 8%), β-pinene (9%, 1%) [19].…”

The chemical composition of the essential oils obtained from the dried leaves of five species of the genus Eucalyptus (E. camaldulensis, E. deglupta, E. grandis, E. torelliana, E. urophylla) growing in Côte d'Ivoire, was analyzed by means of GC and GC/MS. The density and the refractive index were measured. The major components of all these oils are: α-pinene, β-pinene, α-phellandrene, limonene, γ-terpinene, p-cymene and β-caryophyllene. The particularity of these oils is their monoterpene hydrocarbons major components.
