Establishment of the chromatography fingerprint of Compound Danshen Dripping Pills by HPCE / 中成药

ABSTRACT

AIM: To establish an HPCE method for determining the fingerprint of Compound Danshen Dropping Pill.(Radix et Rhizoma salviae miltiorrhizae,Radix et Rhizoma notoginseng,Borneolum Syntheticum) METHODS: A standard fingerprint was set up under following conditions capillary,50 ?m (id)?50.0(eff.41.5) cm,uncoated;detector,UV 203 nm;injection,50 mbar(10 s);running voltage,20 kV;buffer,50 mmol/L sodium tetraborate and 50 mmol/L boric acid(pH 9.0,containing 30 mmol/L SDS) and acetonitrile(4∶1,v/v). RESULTS: Based on the fingerprints of 10 batches Compound Danshen Dripping Pills,an average electropherogram was used as the standard fingerprint,among which there were 14 characteristic peaks. CONCLUSION: The fingerprint analysis can be used for assessing the quality consistency of Compound Danshen Dropping Pill from batch to batch.
