Abstract: Dorystoechas hastata Boiss. and Heldr. Ex Benthamis a monotypic plant endemic to Antalya province of Turkey. The chemical compositions of the water distilled essential oil of D. hastata different parts were investigated by GC/MS, which cultivated in Konya, Turkey. Three major compounds were identified from the aerial parts of D. hastata. Guaiol was the main component with 26.5 % of the branch essential oil. The leaf essential oil contained20.6 % 1,8-cineole, and the aerial parts contained15.0% borneol, respectively. Additionally, D. hastatacultivated samples were investigated for their macro (P, K, Ca, Mg, Na), micro (Fe, B, Mn, Zn, Cu) and heavy metal (Pb, Cd, Ni, Cr, Co) contents. The phosphorus (P) contents of D. hastata leaf, branch and the aerial parts were found as 3164, 2441 and 1852 ppm, respectively. Also, the amino acid compositions of different parts of D. hastata were investigated by HPLC. Major component of proteins in three different part of the plant was identified as proline. The highest proline content of D. hastata was found, however in the branch as 47.1 mg/100 g. As a conclusion, wihin this present study detailed chemical content of the cultivated D. hastata was investigated for the first time respective to its various parts.
