Abstract

A quantitative method has been developed for determination of the 20-hydroxyecdysone content of Serratula tinctoria (L.). Thin-layer chromatography on silica was performed in two consecutive steps; the first was with chloroform - ethanol and the separation was completed with chloroform - methanol - benzene. Plant samples of different phenophases were collected in 1994, ecdysteroids were extracted, and, after a clean-up procedure, the 20-hydroxyecdysone content was determined by TLC - densitometry.
