However, its potential anticoagulant active ingredients have been unexplored. OBJECTIVES: The study aims to establish an affinity ultrafiltration mass spectrometry (AUF-MS) method for rapid screening of anti-thrombin active components of chuanxiong and to verify it in vitro. METHOD: In this study, the chemical constituents of different parts of chuanxiong were determined. A method for rapid screening of...
