Abstract

The genus Stachys (Lamiaceae) is represented by about 300 species found in the world. Turkey is one of the richest countries in Stachys diversity being represented by 83 species with a level of 48% endemism. In this study, Stachys lavandulifolia Vahl. was collected from Alacabük mountain of Tatvan in Eastern Anatolia. S. lavandulifolia Vahl. subsp. lavandulifolia, known as “dağ çayı, tüylü çay”, is widely consumed in Anatolia as herbal tea. Stachys species belong to one of the oldest medicinal plants that are used both for pharmaceutical purposes and in folk medicine; It is used for the treatment of gastrointestinal and respiratory disorders and is known as an appetizer, carminative, stimulant, digestive, diuretic, and throat pain reliever. Wild plants gathered from nature are cheaper food and important for human health. Thus, in the present study, nutritional value and mineral composition of used parts of selected S. lavandulifolia Vahl. var. lavandulifolia was investigated.
In laboratory analysis, total ash, % N, crude protein, crude ?ber, and pH were examined as nutritional value. Useful minerals (Ca, Cu, Fe, K, Mg, Mn, Na, P, S, and Zn) and some heavy metals (Cd, Co, Cr, and Pb) that are hazardous elements for livings were also determined. The total ash, total nitrogen and crude protein, pH and crude ?ber content of the plants were identi?ed as 7.00%, 1.31%, 8.03%, 6.53% and 38.40%, and respectively. The mineral analysis showed that the wild plants' samples contained considerably high amounts of potassium (17.46g/kg), phosphorus (4.70g/kg), calcium (17.25g/kg), magnesium (2.47g/kg), iron (241.37mg/kg), manganese (22.95mg/kg) and zinc (18.56mg/kg). This work contributed to the nutritional properties of some wild plants, and the results may be useful for the evaluation of dietary information.
