[HPLC determination of caffeic acid in herba Lycopi].
OBJECTIVE
To provide experimental data for the quality control of processed Paeonia lactiflora, a Chinese herbal medicine.


METHODS
Traditional processing of P. lactiflora was simulated, content of paeoniflorin and water extracts among different preparations were assayed by HPLC; The quantitative correlations among different processing conditions were analyzed, the effects of processing parameters on the contents of paeoniflorin and water extracts were assayed and analysed.


CONCLUSIONS
The controlled processing parameters were correlated with covariables which showed that processing procedures was controllable, and the heating temperature was a factor impacting the content of paeoniflorin.
