[Qualitative and quantitative studies on qianliebeixi capsules].
OBJECTIVE
To establish a method of quality control on qianliebeixi capsules.


METHODS
To clarify semen vaccarine by TLC, to determinate the contents of quertin and kaempferol in prepations, by HPLC. Chromatographic conditions: C18 column with METH-0.2%H3PO4(47:53) as mobile phase; the temperature of column was 40 degrees C, and quercetin was detected at 370 nm with flowing rate 1 ml/min.


RESULTS
The spots of semen vaccarine were clear in TLC, no interference in negative contrast. The average recovery rate of quertin was 98.9% and the RSD was 2.2%; the average recovery rate in kaempferol was 100.4% and the RSD was 1.7%.


CONCLUSIONS
The resolution of spots were perfect in TLC, the spots were easy to distinguish, The method is simple, rapid as well as reproducible and can control the quality of qianliebeixi capsules effectively.
