Abstract
The essential oils (EOs) obtained by hydro-distillation of stem and aerial parts of Origanum majorana Linn. (Lamiaceae) were respectively characterized by physical means and analysed using gas chromatography-mass spectroscopy (GC-MS). The components were identified by comparison of their retention indices (RI) relative to C8-C23, n-alkanes sample. A total of 78 compounds were identified in the stem oil of which linalool and estragole were found as main components (41.31 % and 14.14 %, respectively). Whereas 87 compounds were found in oil from aerial part with also linalool and estragole as main components but at different percentages (45.05 % and 25.62 %, respectively). The comparative study showed that out of 87 compounds identified from aerial parts, 50 were found to be similar to that of stem oil but differ in percentage of constituents. The essential oil composition of O. majorana varies according to the different parts of the plant, its growth stage and also with respect to the geographical origin of the plant. This difference in chemical composition and in percentage of constituents between the two parts of the plant is (or could be) attributed to the difference in the anatomical features.
