STUDY ON CHEMICAL COMPOSITION OF Centaurea karduchorum Boiss. SPECIES FROM ENDEMIC PLANTS OF EASTERN ANATOLIA/TURKEY

Abstract

ABSTRACT: Centaurea karduchorum Boiss. belonged to the Asteraceae ( Compositae ) which is represented by 1100 genera and about 25000 species in the world. It has a total 1209 species in the flora of Turkey. In terms of the number of species, Asteracea family is the richest family in our country. The genetic origin of Centaurea genus is turkey which this genus is quite common. This plant used as digestion, diuretic, antipyretic, antidiabetic, anti-inflammatory and antibacterial. Centaurea karduchorum Boiss species spread naturally in the Van lake in the Eastern Anatolia Region of Turkey and is a perennial endemic species. The leaves are consumed as herbal tea by the local people for the treatment of diabetes. In this study, the nutritional values and mineral compositions of Centaurea karduchorum Boiss which grown as wild plants in the Van region of Eastern Anatolia, Turkey were examined. The chemical characters estimated included as N, Na, Mg, K, Ca, P, S, Mn, Fe, Cu, Zn, Cr, Cd, Co as well as total ash, crude protein, crude fiber and pH. A a result of the research, ash content, nitrogen content, crude protein content, pH and crude fiber were obtained as 5.93 %, 1.75 %, 10.93 %, 6.66 and 32.58 %, respectively. Also, the detected some chemical components values were as follows: Potassium content 5.57 g/ phosphorus 1.18 g/kg, magnesium 5.71 g/kg, sulphur 1.12 g/kg, manganese 79.56 mg/kg, zinc 15.18 mg/kg and iron 583.56 mg/kg.
