The trypsin inhibitor activity (TIA) in fresh leaves in Hedysarum alpinum L., H. flavescens Regel & Schmalh. and H. theinum Krasnob. in Central Siberian Botanical Garden Siberian Branch Russian Academy Science (CSBG SB RAS, in the foreststeppe of Western Siberia) was investigated in the vegetative phase of seasonal development. Trypsin inhibitors (PR-6 proteins) play the role of immunity factors, since under various influences on plants, the genes encoding the production of this group of substances are activated. They are synthesized in different plant organs, and are necessary for plant control with biotic and abiotic stresses. TIA in the species was characterized by low (< 20 mg/g dry weight) and medium (≥ 20 mg/g dry weight) values, as we identified. It was found that the TIA values vary at a high and very high degree when determining in fresh leaves, and in the study in dry leaf flour - to medium degree. The preservation of TIA values in the species in the dried leaves is shown. On the basis of this fact, the possibility of studying TIA in these species in dried leaves is justified.
