Notes: Summary Thin-layer chromatographic investigations of ecdysteroids have been carried out to monitor their isolation by column chromatography and droplet countercurrent chromatography as well as to control the homogeneity of the pure products. Isolation scheme and chemical structure of the 20-hydroxyecdysone-22-benzoate and that of three new ecdysteroid compounds, 2-deoxy-1,20-dihydroxyecdysone, 2-deoxyecdysone-22-acetate and 2-deoxy-20-hydroxyecdysone-22-acetate are also presented.
