Abstract:
Taking guizhi fuling capsule (GZFL) for instance, a new method about reference Chinese medicine preparation which was used as standard substance for the quality evaluation of complex Chinese medicine preparation by the fingerprint of reference preparation instead of standard fingerprint was proposed. It could eliminate the errors from different instruments, chromatographic columns and solve the problem of similarity matching in the absence of standard fingerprint. The qualification of reference GZFL was evaluated according to the quality control method of GZFL from Chinese Pharmacopoeia. Then multiple batches of GZFL were estimated, taking fingerprint of reference preparation and standard fingerprint as references, respectively, at different instruments and chromatographic columns. Finally, the packaging and expiration date for reference GZFL were confirmed according to the results of stability investigation. The results indicated that the fingerprint of reference GZFL could be used to assess the quality of GZFL better than standard fingerprint. The data of accelerated stability and long-term stability test demonstrated that reference GZFL was stable in the conditions of double blister package. Therefore, reference GZFL can be used as standard substance in quality control of GZFL.
