In the course of studying the occurrence of phytoecdysteroids 26 of 105 species of the family Caryophyllaceae and 19 of 38 chenopodiaceous species were found to contain ecdysteroids. On the basis of isolations and chromatographic examinations carried out so far 20-hydroxyecdysone (β-ecdysone) proved to be the main ecdysteroid component in each case. Of the associate compounds 2-deoxy derivatives seem to occur regularly in Silene species of the family Caryophyllaceae. Studies of several species belonging to further 5 families of the Centrospermac suggest that the occurrence of ecdysteroids is characteristic of certain genera of the family Amaranthaceae in addition to the two families above. The frequent occurrence of ecdysteroids is remarkable in the species Silene, Alelandrium and Lychnis which belong to the subfamily Silenoideae of the family Caryophyllaceae.
