Hydrodistilled leaves and fruits of Hoslundia opposita yielded 0.54% and 0.65%v/w of essentials oils. Investigation by GC and GC-MS revealed that the bulk of the oils were constituted by oxygenated monoterpenes (81.3 and 81.4% for the leaves and fruits, respectively). The principal constituents of the leaf oil were 1, 8-cineole (72.3%), terpineol (7.2%), sabinene (4.5%), thymol (4.2%) and car-3...
