There are 445 species in the Flora of Turkey. Plenty of species of Astragalus are used in traditional medicine in many countries such as European Countries, Turkey, China, India etc. They are used for treatment of diabetes, nephritis, leukaemia, and uterine cancer. In addition, they are used as an antiperspirant, diuretic, and tonic drug. Astragalus sibthorpianus is endemic to Uludağ mountain in Turkey. In this study for the first time, the chemical composition of n-hexane extract of plant material was investigated using GC-MS. The whole plant material was dried and powdered and macerated with MeOH at room temperature. The concentrated MeOH layer was extracted with n-hexane for the apolar constituents. The crude n-hexane extract was derivatized and identification of each component was exhibited by Wiley library data search.eninfo:eu-repo/semantics/openAccessEngineeringMühendislikArticle10.38088/jise.570007313237
