[Phytotherapeutic aspects of diseases of the circulatory system. 6. Leuzea carthamoides (WILLD.) DC: the status of research and possible use of the taxon].

Leuzea carthamoides (WILLD.) DC., Asteraceae, has become an important taxon usable in human practice and animal production in recent years. Originally an endemic plant of southern Siberia, now it is widely grown not only in the Union of Independent States, once the original region of introduction, but also in central and eastern Europe. The principal constituents of the whole plant are ecdysteroids (5 beta-cholest-6-on-7-ene derivatives) and flavonoids. In addition, the aerial part contains sesquiterpenic lactones of the guajanolide type, and the roots contain polyines (on the thiophene base). The present paper comprehensively discusses the occurrence, content and biological activity of these substances, the preparations manufactured from the plant, their use in therapeutic practice, food manufacture and animal production in the world and the Czech Republic. The plant has certainly become a taxon with prospects in the Czech Republic, particularly as the source of 20-hydroxyecdysone, which is getting into the limelight in the world.
