Extraction and Analysis of Washington tree seed oil and Kulgan (Silybum marianum) seed oil

In this study, the process of separating and analyzing oils from some plant seeds such as Washingtonia tree Silybum marianum(kulgan) Soxhlat apparatus was used in extraction process, where performed using organic solvents (Hexane Petroleum ether). Then appreciation percentage oil these plants. It found that marianum contain a higher than tree. Then, active functional groups were identified (FT-IR) spectrum. The composition fatty acids plants also studied technique gas chromatography (GC). This analysis showed five saturated three unsaturated acids, ranged between 1.2-42.7%, while kulgan 3.4-54.5%. Also, physical chemical properties extracted (density, acid value, refractive index, flash point) measured.
