[The results of experimental study of phytoecdysteroids as erythropoiesis stimulators in laboratory animals].

Phytoecdysteroids alpha-ecdysone, 2-desoxyecdysterone, ecdysterone, sileneoside A, and turkesterone isolated from Rhaponticum carthamoides (Willd.) IIjin, Silene brahuica Boiss and Ajuga turkestanica (Rgl.) Repeated administration of brig increased the content of erythrocytes and hemoglobin in the blood of intact rats. The most active of them--ecdysterone, sileneoside A, and, particularly turkesterone, cause also a marked effect on red blood regeneration in hemotoxic phenylhydrazine anemia. In its capacity for simulating erythropoiesis turkesterone resembles the well-known steroidal anabolic drug nerobol.
