Microelement contents and fatty acid compositions of Rhus coriaria L. and Pistacia terebinthus L. fruits spread commonly in the south eastern Anatolia region of Turkey

Sumac (Rhus coriaria L.) and terebinth (Pistacia terebinthus L.) are two important spice plants of south eastern Anatolia, Turkey. Nutrients, physical properties including moisture, ash, dry matter, protein, fatty oil and essential oil content, along with Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Na, Ni, Pb, Zn and characteristics of fruit sizes and fatty acid compositions of both plants were determined from ripe fruits. The free fatty acid content was determined in the fruit oil, and the main fatty acids of sumac and terebinth were identified by gas chromatography/mass spectrometry. They included oleic, linoleic, palmitic and stearic acids in a ratio of 37.7% and 34.8%, 27.4% and 17.3%, 21.1% and 21.7% and, 4.7% and 2.5%, respectively. The fruits of both plants were rich in oil, fatty acids and minerals, suggesting that they are valuable for using in food. The data may also be useful for the evaluation of nutritional information.
