Abstract:
Objective: To investigate the positioning based on the relative retention time of fingerprinting and to establish a new quality evaluation method for traditional Chinese medicine preparations, using one chemical reference substance to calcutate multi- components simultaneously. Methods: Employed icariin as the maker component, icariin relative correction factors (RCF) of epimedin C to icariin, asperosaponin VI to icariin, psoralen to icariin and angelicin to icariin were ealeatated in the chromatographic conditions for determination of the four components in Xianling Gubao Capsule (XGC). The contents of icariin were determined by external standard method, and those of epimedin C, asperosaponin VI, psoralen and angelicin were calculated by icariin and their RCF. The accuracy of the new method was evaluated by comparing the relative retention times and calculating the content which using different brands columns for determination. Results: The analysis methods were established,the linearity was good when sample volume was in the range of at 8.2—328.0 ng for icariine(r = 0.999 5), 0.055 6—2.224 μg for epimedin C (r = 0.999 6), 0.144 1—5.764 μg for asperosaponin VI (r = 0.999 6), 5.4—215.2 ng (r = 0.998 0) for psoralen, 6.6—265.6 ng (r = 0.998 5) for angelicin. The average recoveries of asperosaponin VI, psoralen and psoralen were 97.59%, 98.58%, 98.11%, 97.86%, 98.22%, respectively. The RSDs of recovery were all less than 2.0%; There has been no significant difference between the calculated contents and the determined contents, according to the angle cosine value. Conclusion: The method can control the components without providing epimedin C, asperosaponin VI, psoralen, and angelicin reference. The method is not only save reference substance and medicine resources, but also suitable quality evaluation pattern for TCM preparation. This new method made fingerprinting more meaningful in TCM quality control.
