[Studies on quality standard of Peucedanum praeruptorum].
OBJECTIVE
To establish a quality standard of Peucedanum praeruptorum for Chinese Pharmacopoeia (2005).


METHODS
The presence of (+/-)-praeruptorin A were identified and assayed by TLC and HPLC, respectively.


RESULTS
Linearity of marker was obtained over the range of 0.17696-0.88480 microg (r=0.9999). The average recovery rate was 99.72% (RSD=0.40%).


CONCLUSIONS
TLC is specific. The method of quantity is accurate, reappearance, simple, rapid, and suitable for the quality control of P. praeruptorum.
