A reliable quality control system is essential for ensuring the clinical efficacy and safety of medicines. However, past work on quality control of natural medicines has been focused mainly on the quantification of indicator components and the characteristic chemical fingerprint which provide qualitative information only and rarely provide quantitative information. Herein, a fusion of the Comprehensive Euclidean quantitative fingerprinting method (CEQFM) and multi-component quantification, on-line UV total dissolution methods based on the Dissolution-systematically quantitative fingerprint method (DSQFM) were developed for quality control of Gegen Qinlian tablets (GQTs). Furthermore, DPPH• was used to evaluate the antioxidant activity of GQTs and construct the spectrum-effect relationship. Based on these strategies, the 22 batches of GQTs were classified into six grades by CEQFM (0.898 ≤ Sm ≤ 0.986, 74.4 % ≤ PE ≤ 149.7 %) and seven grades by DSQFM (0.978 ≤ Sm ≤ 1.000, 50.64 % ≤ Pm ≤ 142.3 %), and 8 active ingredients were quantified simultaneously, with the total contents of all the 8 components spanned from 66.47 to 120.40 mg/g. In the in vitro dissolution test, the dissolution curves of 10 batches of GQTs were very similar (Sm > 0.9, 70 %< Pm<130 %, f2>50). Furthermore, the spectrum-effect relationship was applied to screen out the potential antioxidant active components, such as puerarin, baicalein, baicalin, berberine hydrochloride, palmatine chloride, etc. This method can quickly evaluate the quality of GQTs from the aspects of quantitative fingerprinting, dissolution, multi-component, and antioxidant efficacy. The study provides a new approach to quality control and quality consistency evaluation of natural medicines.
