| Abstract | ||||
| Pure essential oils are extracted from various parts of plants and are widely used in various fields of industries, such as perfumery and pharmaceutical industries. These essential oils have a high commercial value because of their therapeutic properties. The objective of this study is to study the behavior of rosemary oil extraction by using both steam distillation and hydro distillation method including quantity, components and ratios of distilled oil analysis and oil analysis. Gas chromatography for the effect of extraction time (5, 10, 15, 30, 60, 90 and 120 min) on yield and composition of essential oil obtained by water distillation method and steam distillation method at three different levels of water vapor flow (3 l / min, 6 l / min and 9 l / min) was also investigted. This research revealed different behaviors of the main components of rosemary oil. α-pinene and 1.8-cineole and camphor in the treatment with the amount of vapor flow rate. Experience has shown that steam distillation method is better than water distillation based on the ratio of oil and its components. | ||||
