    For many diseases, medicinal plants have been used in treatment since ancient times. The relevance of research on medicinal plants is growing day by day. This is due to the fact that the effect of medicinal plants is higher and the effect of chemical drugs is stronger. Currently, there are numerious studies on the effects of medicinal plants and it is proven that they act more sparingly than chemical drugs. In this regard, genetic taxonomic determination will be more effective than morphological identification of medicinal plants. Thanks to the bioinformatics, it is increasingly possible to identify genes isolated from plants, align them with genes in a database, and perform phylogenetic analysis. In our work, DNA was isolated from the leaves of Aegopodium alpestre Ledeb., and the rbcL gene was sequenced, then a phylogenetic analysis was carried out to determine the relationship with Aegopodium L., as well as with representatives of the Umbelliferae family. The study showed that the plant Aegopodium alpestre Ledeb. according to the sequences of the rbcL gene, it is closer to the genus Aegopodium L, in contrast to other representatives of the Apiaceae family. However, between them were not found strong similarities.

    The study investigates the current state, floristic composition, and ecological characteristics of Gentiana tianschanica populations in the Ile-Alatau region, part of the Ile-Alatau National Park, Kazakhstan.Gentiana L., an ancient boreal genus, includes 31 species in Kazakhstan, such as the endemic Gentiana dschungarica.Known for medicinal uses, especially for gastrointestinal and urogenital disorders, interest in gentians has risen for ornamental and pharmacological applications.Nine natural populations of G. tianschanica were studied in diverse ecological and phytocoenotic conditions of the Ile-Alatau mountains.Soil analyses revealed significant differences in the physicochemical properties of the species' habitats.In the Kimasar Gorge, mountain-meadow chestnut soils with a light loamy texture were observed, while the Big Almaty Gorge featured dark chestnut soils rich in humus (7.36-18.78%)and nutrients such as nitrogen (120.4-140.0mg/kg), phosphorus (58-98 mg/kg), and potassium (470-1000 mg/kg).These findings emphasize the species 'adaptation to varying altitudinal and climatic zones.Phytochemical analysis showed G. tianschanica is rich in bioactive compounds, including phenolics, bitter glycosides, flavonoids, and alkaloids.Total phenol content reached 1567.17-9008.20mg of gallic acid/100 g, with the highest levels in leaves.Flavonoids (up to 1358.25 mg catechin/100 g) and vitamin C (up to 244.7 mg/100 g) were significant.Syringic acid (1685.8mg/100 g), quercetin (317.4 mg/100 g), and chlorogenic acid (237.5 mg/100 g) highlighted antioxidant and antiinflammatory potential.The antioxidant activity, particularly in leaves, reached 530.30 mg Trolox/100 g.Anthropogenic threats, including overgrazing and habitat disturbance, have led to declining populations, necessitating conservation strategies like habitat monitoring, protective regimes, and sustainable medicinal plant use.This study underscores the ecological and phytochemical significance of G. tianschanica, which is vital for biodiversity conservation and pharmaceutical development.
