| Objective: To evaluate the technical capability of relevant laboratories to perform the identification of Fritillariae Cirrhosae Bulbus by the method of PCR-RFLP method according to Chinese Pharmacopia 2015 edition and to promote the application of molecular biological technology in the field of TCM identification, a proficiency test of the identification of Fritillariae Cirrhosae Bulbus by the method of PCR-RFLP was organized by National Institutes for Food and Drug Control. Methods: Samples for testing were in the form of powder and the homogeneity and stability of the samples were examined. The samples were classified into two types, positive and negative, which was randomly and single blindly distributed to the laboratories participating in the proficiency test. The laboratories carried out the tests according to the instruction book as designed and records were made in the specific forms. The satisfied judgment was only made when the testing result was in accord with the nature of the sample (positive or negative). Finally, Results from different laboratories were collected and analyzed. Results: A total of 50 laboratories participated in the proficiency test, 26 laboratories were satisfied, accounting for 52%, 24 laboratories were unsatisfied, accounting for 48%. 3 laboratories failed to return the results as required and were considered to be unsatisfied. The laboratories affiliated to cities got the highest rate of the satisfaction, 70.6%. Conclusion: The overall ratio of the satisfied is low. The technical level of the identification of Fritillariae Cirrhosae Bulbus by the method of PCR-RFLP needs to be improved. |
