Chemical Contents of Some Species of Teucrium Genus Distributed in Van Flora

Abstract

Lamiaceae family, including the Teucrium genus, is Turkey's third richest family. Albeit Teucrium's gene center is the Mediterranean Territory, they grow in almost every habitat and altitude of the world. In this study, objective of this study was to determine the nutrient and mineral contents of two species (Teucrium polium L. and Teucrium chamaedrys L. subsp. chamaedrys) belonging to Teucrium genus distributed naturally in Van province in Eastern Anatolia Region. In the plant samples, total ash, crude protein, pH, crude fiber and some mineral including N, Na, Mg, K, Ca, P, S, Fe, Zn, Mn, Cu, Cr, Cd, Co, Pb contents were observed. When the data obtained were examined, it was determined that the chemical composition differs based on species. Teucrium polium and T. chamaedrys species sustained a content ratio of 1.76-0.77%, 11.0-4.81%, 6.33-5.03%, 6.07-6.07%, and 36.83-37.15% for total nitrogen, protein, pH, total ash, and fiber, respectively. In addition, it was determined that Teucrium species sustained different potassium (7.51-4.34 g kg(-1)), phosphorus (4.41-1.37 g kg(-1)), magnesium (3.57-1.81 g kg(-1)), sulfur (2.22-1.27 g kg(-1)), manganese (34.71-50.78 mg kg(-1)), zinc (28.41-26.22 mg kg(-1)) and iron (255.35-221.22 mg kg(-1)) ratios, respectively. In terms of heavy metal content, the highest values were obtained from T. chamaedrys subsp. chamaedrys.
