title: [Spectrum-Effect Relationship of GualouXiebai Dropping Pills on Myocardial Ischemia].
abstract: OBJECTIVE
  To study the relationship between HPLC characteristic spectrum and pharmacodynamics on anti-myocardial ischemia of GualouXiebai dropping pills.
  
  
  METHODS
  HPLC characteristic spectrum of GualouXiebai dropping pills was established, dropping pills were divided into five dose groups (3.75, 11.25, 22.5, 33.75 and 45 g/kg, equivalent to the crude herb g/kg), the mice were orally administered dropping pills once daily for 7 d, 90 min after the mice were given by intraperitoneal injection of isoprenaline to establish myocardial ischemia models, the level of CK in blood plasma were detected; Then, the correlation between characteristic spectrum and biochemical index CK was studied by grey relational analysis method.
  
  
  RESULTS
  The correlation between each common peak and CK had gradually increased with the dose increased from 3.73 g/kg to 33.75 g/kg, but when the dose reached to 45 g/kg, the correlation between each common peak and CK had decreased. The variation trends of correlation of spectrum-effect relationship for different dose were similar,but the correlation variation trend of the efficacy on the No. 8 peak in 33.75 g/kg group with the other four groups in the opposite, the change trends of the No. 11 peak in 22.5 g/kg group, the No. 24 peak in 33. 75 g/kg group and the No. 37 peak in 45 g/ kg group with 3.75 g/kg group and 11.25 g/kg group on the contrary. The relational orders of spectrum-effect relationship were not consistent, respectively( the first 15 peaks) :11 > 37 > 24 > 30 > 8 > 21 > 2 > 16 > 1 > 3 > 20 > 15 > 12 > 19 > 7;11 > 37 > 30 > 8 > 21 > 24 > 2 > 1 > 16 > 3 > 27 > 12 > 22 > 20 >10; 8 > 30 > 1 > 2 > 21 > 27 > 31 > 22 > 16 > 12 > 3 > 10 > 9 > 20 > 4; 1 > 2 > 27 > 21 > 31 > 22 > 12 > 16 > 9 > 3 > 10 > 4 > 17 > 30 > 20; 8 > 30 > 1 > 2 > 2 > 2 > 7 > 31 > 22 > 16 > 12 > 3 > 9 > 10 > 20 > 17.
  
  
  CONCLUSIONS
  Anti-myocardial ischemia effect of GualouXiebai dropping pills comes from the synergistic or antagonistic effect among various active ingredients related to the dose. With the difference of the dosage, the relational orders of chemical components to play the role is not the same, but the main components to play a pharmacodynamic of five dose groups are consistent,the existence of the component groups lay a foundation for further study of GualouXiebai dropping pills.
