Objective To identify the chemical components of Angelicae Sinensis Radix-Chuanxiong Rhizoma herb pairs and their prototype components into blood and metabolites after oral administration in rats. Methods Based on the ultra-performance liquid chromatography coupled with Orbitrap high-resolution mass spectrometry technology (UPLC-Orbitrap-HRMS), the chemical components of Angelicae Sinensis Radix-Chuanxiong Rhizoma herb pairs were analyzed and identified in combination with reference substance, self-established database, relevant literature information, Compound Discoverer 3.3, and Xcalibur qual browser 4.3 software; Drug-containing serum were prepared from normal rats by intragastric administration. The prototype components and metabolites were identified by comparing drug-containing serum with blank serum. Results A total of 69 chemical components were identified in the Angelicae Sinensis Radix-Chuanxiong Rhizoma herb pairs, including 24 phthalides, 24 organic acids, eight amino acids, seven nitrogen-containings, four coumarins, one lignan and one flavonoid. A total of 30 prototype components were identified in the drug-containing serum, including 15 phthalides, 13 organic acids, and two coumarins; 45 metabolites were identified in vivo, including 32 phthalides and 13 organic acids. Conclusion The chemical components, prototype components, and metabolites of Angelicae Sinensis Radix-Chuanxiong Rhizoma herb pairs were clarified.
