The activity-integrated fingerprints of Danshen injections have been established by high-performance liquid chromatography coupled with chemiluminescence detection (HPLC-CL) according to their antioxidants activity scavenging hydrogen peroxide. The authentication and validation of the activity-integrated fingerprints were performed. Then, a data-level information fusion method was employed to capture the chemical and antioxidant information encoded in HPLC-CL fingerprints. Finally, based on the fusion results, the quality of different batches of Danshen injections samples were further evaluated by similarity measure. In comparison with conventional fingerprints, the activity-integrated fingerprints, which simultaneously contained the chemical characteristics and antioxidant activities of constitutions could comprehensively and properly reveal the quality characteristics of the Danshen injections. In conclusion, the antioxidant-activity-integrated fingerprints were suitable for quality control of Danshen injections. This study could clearly demonstrate that the activity-integrated fingerprint was a powerful and meaningful tool to comprehensively improve the quality control of complex herbal medicines.
