Digitized HPLC fingerprints of Compound Danshen Dropping Pills / 中成药

ABSTRACT

AIM:To establish a digitized HPLC fingerprint of Compound Danshen Dropping PilLs (CDDP). METHODS:The RP-HPLC condition was optimized by the chromatographic fingerprint relative index (Fr). The chromatographic fingerprints were characteristically digitized and evaluated by the software of the digitized evaluation system of Traditional Chinese Medicine (TCM) with the super information characteristics. RESULTS:15 co-possessing peaks were selected as the fingerprint peaks of CDDP by taking protocatechualdehyde peak as the referential peak to establish the digitized fingerprint and the important digitized information for its quality control was obtained. The stabilities among different lots of samples were evaluated by the dual qualitative and dual quantitative similarity method. CONCLUSION:The fingerprints can perfectly reflect the authentical quality of CDDP.
