[Quality evaluation of prepared slices of Paeonia lactiflon--determination of paeoniflorin by HPLC].
OBJECTIVE
To establish the quality criteria of the prepared slices of Paeonia lactiflon.


METHODS
RP-HPLC was used for the determination of paeoniflorin in 10 lots of samples by ultrasound-assisted extraction.


RESULTS
The samples were extracted with 50% methanol. Seperation of the solution was performed on an ODS column with a mobile phase of acetonitrile-water (18:82), detected at 230 nm.


CONCLUSIONS
The method is simple, repeatable, accurate and applicable.
