Abstract
Eight Silene species include S. brachuica , S. guntensis, S. linicola , S. oreina, S. praemixta , S. pseudotites, S. viridiflora and S. wallichiana were screened for the main ecdysteroid 20-hydroxyecdysone by HPLC using the UV spectroscopy. HPLC analyses have shown all Silene plants except S. oreina contain 20-hydroxyecdysone, but in different concentration. Studies have shown that S. praemixta and S. viridiflora are rich phytoecdysteroids containing plants and the yields of total ecdysteroids are 2.0% and 1.6%, respectively. The results of investigation species of Silene : S. brachuica, S. praemixta, S. viridiflora, S. guntensis, S. linicola, S. pseudotites and S. wallichiana showed that the yields of 20E of these plants are 0.03, 0.27, 0.35, 0.082, 0.367, 0.071 and 0.08% respectively. The plants of S. linicola, S. praemixta and S. viridiflora suggested to be used for production of ecdysteroids containing preparations.

Summary
Phytoecdysteroids are contentedly widespread in the plant world. The application of phytoecdysteroids is a promising alternative to the use of anabolic-androgenic steroids because of the apparent lack of adverse effects. The tonic and anabolic preparations are produced from the plants Rhaponticum carthamoides (Asteraceae), Pfaffia irisinodes (Amaranthaceae), Ajuga turkestanica. The limited availability of the natural resources and relatively low content of 20E in these plants leads to a high cost of these preparations. More than 170 Silene species (family Caryophyllaceae) have been analyzed for their phytoecdysteroid content, and 140 of them were found to be positive and 93 different ecdysteroids have been detected from these plants. In this study we screened content of 20E from aerial parts 8 Silene species plants: S. brachuica Boiss., S. guntensis B.
