The chemical composition of Scorzonera kotschyi Boiss., belonging to the genus Scorzonera, has not been intensively analysed based on its volatile secondary metabolite and phenolic composition in Türkiye. In different plant parts of S. kotschyi, their volatile secondary metabolites were determined using GC–MS, and their phenolic composition was determined using HPLC. This work revealed that fractions of Scorzonera kotschyi were clearly different from each other based on chemical composition. Fifty-eight different volatile secondary metabolites were determined in separate plant fractions of S. kotschyi. β-caryophyllene was detected in the highest amounts, with 57.74% in root, 58.13% in stem, 3.48% in flower, 22.22% in seed, and heneicosane was detected with 56.62% in flower parts. Aromadendrene was detected with a high amount of 72.85% only in leaf parts. β-Caryophyllene was the predominant volatile secondary metabolite in root, stem, flower, and seed parts of S. kotschyi. Biplot Analysis was used to distinguish different fractions of this investigated plant based on their chemical composition, which revealed high variability. Various constituents of medicinal significance could be assessed in S. kotschyi. These constituents could be extracted and used for fundamental research.
