Abstract: Compound Liangmianzhen buccal tablet is a drug that exhibits notable effect on cough and diphtheria. Since the accessory has been changed, along with the difficulties in traditional Chinese drug-evaluation, it is imperative to set up a reliable method to evaluate the drug and ensure the quality consistency. First, the content of the Compound Liangmianzhen buccal tablets reflected by fingerprints were evaluated by the comprehensive linearly quantified fingerprint method and systematic quantified fingerprint method, in which thirteen fingerprint peaks was selected and gallic acid was chosen as the reference peak. The results of the two methods showed all batches in grades 1–3 of above good level with the qualitative similarities of Sl and Sm above 0.90, and the quantitative ones of Pl% and Pm% from 80%–120%, indicating all samples far qualified. Second, the measurement of antioxidant effect based on DPPH free radical clearance test has demonstrated the consistency between the old prescription group and the new ones and further dug up the major antioxidant compositions. Third, dissolution profiles at 190 to 400 nm that evaluate the curative effect consistency were evaluated by f2 and the correlation of the dissolution curve. In conclusion, the combination of 3 kinds of analysis methods can comprehensively assess the quality of the traditional Chinese drug and be served as a routine procedure to evaluate the herbal medicine consistency.
