Factors affecting the content of 20-hydroxyecdisone in leuzea carthamoides (review)

Abstract

Data are presented, published in the period from 2005 to 2019, devoted to the study of the influence of factors of the abiotic environment (temperature, humidity, illumination, soil), anthropogenic impact (growing conditions, fertilizers, growth regulators, harvesting, drying and storage conditions), as well as vegetation, ontogenesis and other conditions for the content of 20-hydroxyecdysone in the safflower leuzea. Safflower Leuzea (Rhaponticum carthamoides (Willd.) IIjin) is a promising fodder plant that has immunostimulating and immunomodulatory properties and has a positive effect on metabolic processes. It is important to study the factors and conditions that contribute to both natural biosynthesis and the accumulation of physiologically active substances in fodder plants, and the preservation of their original content in raw materials during the harvesting and storage process. Natural and climatic conditions of Perm Krai are favorable for the growth of Safflower Leuzea. It is assumed that it is possible to regulate the 20E content in plant material through the creation of an optimal technological regime and a set of agrotechnical methods during cultivation. Stressful situations of short duration can lead to an increase in the content of secondary metabolites in plants in response to environmental influences.
