Comparative GC analyses of ripe fruits, leaves and floral buds essential oils of Tunisian Myrtus communis L.
Abstract
The chemical composition of essential oils obtained by hydrodistillation from Tunisian wild growing myrtle ripe fruits, leaves and floral buds was examined by GC and GC-MS. The yields of hydrodistilled oils obtained from different plant parts were: leaves 0.5%, floral buds 0.2% and ripe fruits 0.02%. Significant differences were found in the concentration of main constituents of the oils: α-pinene [48.9% (floral buds), 34.3% (fruits), 23.7% (leaves)], 1,8-cineole [15.3% (floral buds), 26.6% (fruits), 61.0% (leaves)]. The leaves oil contained less linalool than floral buds and ripe fruits oils. Tunisian myrtle is characterized by the absence of myrtenyl acetate.
