[Comparison of pharmaceutical chemistry difference of effective parts from yin teng gu bi kang prescription in normal rats and rats with acute blood stasis].

[Article in Chinese]

Abstract

OBJECTIVE:

To elucidate the material basis of Yin Teng Gu Bi Kang Prescription (YTGBKP) for efficacy of promoting blood circulation by means of comparing the pharmaceutical chemistry difference of effective parts in normal rats and rats with acute blood stasis.

METHODS:

The pharmaceutical chemistry fingerprints of effective parts under physiological and pathological status (acute blood stasis) were established by HPLC,and the in vitro and in vivo chromatographic peaks were compared and analyzed.

RESULTS:

Five batches of drug-containing plasma samples had 14 chromatographic peaks under normal physiological status,among which 3 rooted in plasma, 9 existed originally in YTGBKP,2 were metabolites. The compound with retention lime at 12 min was identified as ferulic acid by comparing with reference standard; While under pathological status (acute blood stasis), five batches of the drug-containing plasma samples had 14 chromatographic peaks, among which 3 rooted in plasma, 9 existed originally in YTGBKP, 2 were metabolites. The compounds with retention time at 12 min and 32 min were identified as ferulic acid and icariin respectively by comparing with reference standards. There were 10 common peaks under normal physiological and pathological status (acute bloodl stasis) excluding peaks in blank plasma. The intensity of the common peaks produced under pathological status was stronger than that under normal physiological status significantly; Variance analysis showed that there were significant differences (P < 0.05) in peak areas of 3 peaks.

CONCLUSION:

Blood stasis has influence on the absorption and metabolism of most ingredients from YTGBKPi; Prototypes and metabolites may be the effective substance on promoting blood circulation.
