OBJECTIVE
To study the chemical constituents from the roots of Rehmannia glutinosa.
METHODS
The compounds were isolated by various chromatographic methods and identified by spectroscopic analysis.
RESULTS
Twelve compounds were isolated and their structures were identified as
Separation of the immunosuppressive principles from Rehmanniae radix was done by monitoring hemolytic plaque-forming cells (HPFC) inhibitory activity to give two new phenethyl alcohol glycosides: jionosides A1 (4) and B1 (5), along with six known compounds: acetoside, isoacteoside, purpureaside C,
