Abstract
48 Silene species (Caryophyllaceae family) were tested by TLC/densitometry for ecdysteroids.
It turned out that 50 % of the species contained 20-hydroxyecdysone (
-ecdysone) justifying that this compound is of widespread occurrence in this genus. Silene italica, S. nutans, S. otites contain, beside 20-hydroxyecdysone, integristeron A, both in varying quantities. Silene otiotes produced the highest ecdysteroid concentration in June and July, when S. nutans contained the least ecdysteroids.
If the organs were compared with each other, in the case of both species, there is a decrease in the yield in the order inflorescence, leaf, root and stem.
