Abstract

The ecdysteroid profile was investigated by HPLC, and it has been found that 2-deoxyecdysone, 2-deoxy-20-hydroxyecdysone, polypodine B, 20-hydroxyecdysone, and integristerone A are synthesized in the aerial part. The composition of biologically active substances (BAS) has been investigated, and the presence of triterpene glycosides, alkaloids and flavonoids has been confirmed; tannins have been detected for the first time. It has been shown that the ecological conditions, such as altitude above sea level and humidity, influence the ecdysteroid composition and BAS levels.
