[A new ecdysone hormone rhaponticum from Rhaponticum uniflorum (L.) DC].
OBJECTIVE
To study the chemical constituents of Rhaponticum uniflorum.


METHODS
Solvent extraction, separation by silica gel column chromatography and identification by physico-chemical properties and spectral data.


RESULTS
A new ecdysone hormone, rhaponticum (1) was isolated from the root of R. uniflorum together with a known compound ecdysterone(2).


CONCLUSIONS
The two compounds were obtained from the plant for the first time.
