Abstract:
By preparing 10 batches of substance benchmarks freeze-drying powder( lyophilized powder),the methodology of the characteristic spectrum and the content of index component for substance benchmarks of Qingwei San was established. The characteristic peaks and the similarity range of the characteristic spectrum,the contents and the transfer rate range of isoferulic acid,palmatine and paeonol,and the paste-forming rate range were determined to define key quality attributes of substance benchmarks of Qingwei San. In the10 batches of substance benchmarks of Qingwei San,the similarity of characteristic spectrum was higher than 0. 90. In further comparison of the characteristic peak information,a total of 16 characteristic peaks were identified,including 5 characteristic peaks from Cimicifugae Rhizoma,5 characteristic peaks from Coptidis Rhizoma,2 characteristic peaks from Angelicae Sinensis Radix and 4 characteristic peaks from Moutan Cortex. The content of isoferulic acid was 0. 10%-0. 18%,with the average transfer rate of 49. 82%±4. 02%. The content of palmatine was 0. 17%-0. 31%,with the average transfer rate of 15. 84% ±2. 39%. The content of paeonol was 0. 41%-0. 75%,with the average transfer rate of 23. 41%±3. 23%. The paste-forming rate of the 10 batches of substance benchmarks were controlled at 27%-33%,with the transfer rate between the theoretical paste-forming rate and the actual paste-forming rate was 86. 59%±3. 39%. In this study,the quality value transfer of substance benchmarks of Qingwei San was analyzed by the combination of characteristic spectrum,the content of index component and the paste-forming rate. A scientific and stable evaluation method was preliminarily established,so as to provide the basis for subsequent development and quality control of relevant preparations of Qingwei San.
