The aim of this project is to extract the essential oil from different plants which are Thyme, Lavender, Sage, Rosemary, Mint, Jasmine, Lemon leaves and Lemon peels and from different seeds which are aniseeds, pumpkin seeds, lemon seeds and grape seed. These oils are used in different fields of industry such as pharmaceutical, cosmetics, food and soap.
The oils from the seeds are extracted by solvent extraction method by ethanol and n-hexane with solid liquid ratio of 1:3; the seeds are cleaned, grinded, mixed with solvent, filtered, and the solvent was separated by rotary evaporator. The oils from plants are extracted by steam distillation method; the process is operated at 1 bar, the steam is operated at low flow rate and three condensers were used.
The amount of oil which was achieved from lemon seeds, aniseeds, pumpkin seeds and grape seeds by using ethanol is (10 ml / 150 g), (7 ml / 100 g), (14 ml / 100 g) and (10 ml / 150 g) respectively. And by using n-hexane is (28 ml / 150 g), (13 ml / 100 g), (34 ml / 100 g) and (12 ml / 150 g) respectively.
The amount of oil which was achieved from Sage is (3.5 ml / 1500 g), Thyme oil is (2 ml / 1600 g), and Rosemary oil is (4.5 ml / 1400), Mint oil is (1.5 ml / 1200 g), Lavender oil is (3.2 ml / 1600 g), Jasmine oil is (1.8 ml / 200 ml), Lemon leaves oil is (3 ml / 1300 g) and Lemon peels oil is (2.5 ml / 1100 g).
