Popis: Recently, there has been renewed interest in researching valuable seed oils because of their economic importance. The aim of this study was to evaluate the effects of different extraction solvents on the quality of extract oils. Tecoma stans var. velutina seed oil (TSSO) was extracted using hexane, petroleum ether, chloroform, and ethanol as solvents. The results showed that TSSO contained a high content of monounsaturated fatty acids (MUFAs), including palmitoleic and petroselinic acids. The content of palmitoleic and petroselinic acids were significantly affected by the solvent type. Moreover, the total tocopherol and tocotrienol content were significantly higher in oil extracted with ethanol. The oxidative stability index (OSI) values were higher in oil extracted with hexane at different temperatures. The results were compared with findings based on T. stans var. stans seed oil cultivated in Saudi Arabia to evaluate the effect the plant variety and of location and climatic conditions on TSSO composition.
