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.
OBJECTIVE
To study the chemical constituents of the root of Rhaponticum uniflorum.
METHODS
Separation and purification were performed on silica gel and Sephadex LH-20 column chromatography. Their structure were elucidated on the basis of physicochemical and spectral analysis.
