Author: Salih, Abd Elmoez Salih Mahfouz
Abstract: A large number of herbal materials contain Essential Oils with extensive bioactivities. It is important to acknowledge plants and their medicinal value. There are a variety of methods for obtaining volatile oils from plants, Such as extraction by organic solvent and steam distillation. In this study steam distillation was used to extract oil from spearmint because this method is recommended for oil extracted for medical purposes. In addition ,reputable distiller will preserve the original qualities of the plant oil. Analysis of Essential oil was done using Gas Chromatography-Mass Spectrometery (GC-MS), in order to evaluate the essential Oil qualitatively and quantitatively. The GC-MS analysis showed twenty nine peaks each contained several components. The major components were: Carvomenthone (4.47%), myrcene (4.49%), piperitone (5.24%), limonene (19.99%) and carvone (42.26%) of the total component . Physico-chemical properties of the extracted oil were determined according to the British Standards Institute (BSI) . Results were as follows : Acid value (6.45 mg), saponification value (42.08 mg), Peroxide value (6.6 mg), Iodine value (130.28 mg), Refractive index (at 25.1°C) (1.488) and Density was 0.93 at room temperature.
