Peimine, one of the major quality markers in Fritillaria Cirrhosae Bulbus, was expected to become a new anti‐asthma drug. However, its metabolic profiles and anti‐asthma mechanism have not been clarified previously. In this study, a method was developed for the detection of peimine metabolites in vitro by ultra‐high‐performance liquid chromatography coupled with hybrid triple quadrupole time‐of‐flight mass spectrometry. The potential anti‐asthma mechanism was predicted by an integrated analysis of network pharmacology and molecular docking. A total of 19 metabolites were identified with the aid of software and molecular networking. The metabolic profiles of peimine elucidated that the metabolism was a multi‐pathway process with characteristics of species difference. The network pharmacology results showed that peimine and its metabolites could regulate multiple asthma‐related targets. The above targets were involved in various regulatory pathways linked to asthma. Moreover, the results of molecular docking showed that both peimine and its metabolites had a certain affinity with the β₂ adrenergic receptor. The results provided not only important references to understand the metabolism and pharmacodynamic changes of peimine in vitro, but also supporting data for further pharmacological evaluation. It also provided a new perspective for clarifying the functional changes of traditional Chinese medicine in vitro.
