[Preparation of forsythiaside from Forsythia suspensa by high-performance liquid chromato- graphy].
OBJECTIVE
To prepare forsythiaside from Forsythia suspensa by high-performance liquid chromatography (HPLC).


METHODS
A crude extract of Forsythia suspensa was prepared by water extraction and alcohol precipitation prior to polyamide column chromatography. Forsythiaside was prepared from the crude extract by RP-HPLC.


RESULTS
Analysis with HPLC showed that the purity of the prepared forsythiaside reached 98%.


CONCLUSIONS
HPLC is simple and effective for the preparation of forsythiaside from Forsythia suspensa.
