    1,8-Cineole: An attractant for the banana weevil, Cosmopolites sordidus
    (Elsevier, 1996-07) Hassanali, Ahmed; Ndiege, I. O.; Budenberg, W. J.; Otieno, D. O.
    1,8-Cineole was identified as one of the electrophysiologically active components of the volatiles from banana cultivars susceptible to the banana weevil. It was also shown to be an attractant for the banana weevil Comopolites sordidus in laboratory behavioural bioassays. The resistant cultivar did not contain 1,8-cineole. β-Phellandrene, which exhibited electrophysiological activity, but did not show any attraction to the banana weevil, was found only in the resistant banana cultivar.

    Analysis of Essential Oil from Kenyan Eucalyptus Globulus Labill.
    (Faculty of Science Kenyatta University, 1998) Akeng'a, T. A. R.; Chhabra, S. C.
    The essential oil of fresh leaves of Eucalyptus globulus Labill. (Myrtaceae) obtained from Muguga Arboretum, Kiambu District, Kenya, was extracted by steam distillation for varying times and analysed using GC and GC-MS. The optimum time was found to be 5 hours with the yield of the oil being 2.48% while the content of 1,8-cineole was found to be 55.87%. Other constituents in this medical oil include eudesmol, (±)-linalool, B-pinene,trans-citral, carvone and a-terpineol

    Volatile Constituents of Essential Oil of Tarconanthus camphoratus L.
    (Taylor & Francis, 1994) Hassanali, Ahmed; Mwangi, J. W.; Achola, K. J.; Lwande, W.; Laurent, R.
    The leaf oil of Tarconanthus camphoratus (Compositae) was analyzed by GC and GC/MS. Sixty compounds representing ca. 95% of the oil were identified. The major components were α-fencyl alcohol (29.1%), 1,8-cineole (16.5%) and α-terpineol (8.5%).
