Drimys Winteri

The chemical composition of the essential oils obtained by hydrodistillation of stem bark and leaves of Drimys winteri J.R. et G. Foster var. chilensis /DC A. Gray ( Winteraceae) from Chiloe Island (ID) and Continental Chile (Santiago) (CD) were studied by GC and GC/MS. Sesquiterpene hydrocarbons constituted the main chemical groups in the stem bark oils, with α-santalene, trans-β-bergamotene and curcumenes as the major components. Monoterpenes constituted the main chemical groups in the leaves of Island plants with α-pinene (23.1%) β-pinene (43.6%) and linalool (10.5%) as the main components whereas sesquiterpenes (germacrene D 17.6%) and phenylpropanoids (safrole 20.8%) are the most abundant in the leaves of Continental plants.

The essential oils from the leaf, stem-bark and twig of Terminalia mantaly were isolated by hydrodistillation. The volatile oils analysed on Gas Chromatography (GC) and Gas Chromatography – Mass Spectrometer (GC - MS). The identified constituents were twelve, twenty-three and seventeen for the leaf, stem-bark and twig and accounted for 89.57%, 95.77%, 95.92% respectively. Hexahydrofarnesylacetone (30.05%) and Z-pinane (16.71%) were the main constituents in the leaf oil and nonanal (21.16%) and heptanal (10.57%) were principal component in the stem-bark volatile oil. Xylene isomers namely, meta and para (21.98%-23.56%) were the major components of the twig with substantial amount of nonanal (13.64%).
