This study presents a pharmacognostic characterization of the rhizomes of Iris scariosa L. from Central Kazakhstan, including determination of total extractives, mineral composition, and quantitative content of major groups of bioactive compounds. Materials and Methods: The study material consisted of rhizomes of I. scariosa collected during the flowering phase in the Karaagash Forestry (Zhanaarkinsky District, Ulytau Region, Kazakhstan). Bioactive compounds were analyzed using pharmacopoeial and standard methods: spectrophotometry, titration, and gravimetric analysis. Mineral composition was assessed by atomic absorption spectroscopy. All experiments were performed in three independent replicates, and results are expressed as mean ± standard deviation. Results: The rhizomes were dominated by total extractives (17.81 %) and polysaccharides (3.43 %), with moderate levels of coumarins, tannins, and alkaloids, and minimal levels of flavonoids, saponins, and free organic acids. Among macroelements, potassium (51.608 ± 0.051 mg/g), calcium (41.170 ± 0.121 mg/g), and magnesium (8.305 ± 0.028 mg/g) predominated. Microelements Fe, Zn, Mn, Cu, and Ni were present in trace, physiologically relevant amounts, while toxic elements Pb and Cd were not detected. Conclusions: I. scariosa is characterized by the dominance of total extractives and polysaccharides, moderate levels of coumarins, tannins, and alkaloids, and minimal amounts of saponins and organic acids, confirming its pharmacological potential and supporting its prospects for standardization as medicinal plant material.
