Abstract
20-Hydroxyecdysone (ecdysterone) (2β, 3β, 14α, 20R, 22R, 25-hexahydroxy-5β-cholest-7-en-6-one) and 5β,20-dihydroxyecdysone (Polypodine B) present in extracts of species of Helleborus were detected as their trimethylsilylimidazole (TSIM) derivatives by GLC analysis. The MS analysis of 5β,20-dihydroxyecdysone in the purified extract and the GLC characteristics of the sily-lated ecdysteroids are described and discussed as a means of their identification.
