The paper presents the results of studies devoted to the study of the rare for Dagestan species Nectaroscordum tripedale Trautv., Included in the Red Data Books of Russia and Dagestan, as endangered (rarity category 1). The aim of this work was to assess the content of phenolic compounds and the antioxidant activity of the aerial part of N. tripedale. Plant raw materials were collected in the vegetation and flowering phase, and the content of phenolic compounds was studied, both in fresh raw materials and in frozen ones. Determination of the content of phenolic compounds and antioxidant activity was carried out in water - ethanol extracts (70% ethanol solution) according to standard methods. The content of phenolic compounds is higher in fresh raw materials than in dried ones. The analysis showed that the leaves contain more flavonoids and anthocyanins than the rest, and the least of them is in the flower arrows. Evaluation of the total content of antioxidants in water - ethanol extracts from the aboveground part of the Dagestan N. tripedale samples. The data of phytochemical studies are of great importance and contribute to supplementing the available information on the dynamics of the accumulation of primary and secondary metabolites in herbaceous plants on the territory of Dagestan.
