Despite its widespread use, its dynamic metabolism involved remains unclear. Based on the sequential metabolism strategy, blood samples from different metabolic sites were obtained via in situ closed intestine ring integrated with a jugular venous continuous blood supply technique. An ultra\u2010high\u2010performance liquid chromatography\u2010linear triple quadruple\u2010Orbitrap\u2010tandem mass spectrometry method was developed for the identification of prototypes and metabolites in rat plasma. The dynamic absorption and metabolic landscape of flavonoids, saponins, and phthalides were characterized. Flavonoids could be deglycosylated, deacetylated, demethylated, dehydroxylated, and glucuronicated in the gut and then absorbed for further metabolism. Jejunum is an important metabolic site for saponins biotransformation. Saponins that are substituted by Acetyl groups tend to lose their acetyl groups and convert to Astragaloside IV in the jejunum. Phthalides could be hydroxylated and glucuronidated in the gut and then absorbed for further metabolism. Seven components serve as crucial joints in the metabolic network and are potential candidates for the quality control of Danggui Buxue Decoction. The sequential metabolism strategy described in this study could be useful for characterizing the metabolic pathways of Chinese medicine and natural products in the digestive system.<\/jats:p>","DOI":"10.1002\/jssc.202200941","type":"journal-article","created":{"date-parts":[[2023,6,15]],"date-time":"2023-06-15T23:04:35Z","timestamp":1686870275000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Study on the dynamic metabolic characteristic of main active ingredients in Danggui Buxue Decoction by liquid chromatography\u2010tandem mass spectrometry based on in situ sequential metabolism strategy"],"prefix":"10.1002","volume":"46","author":[{"given":"Yanmin","family":"Wang","sequence":"first","affiliation":[{"name":"School of Chinese Materia Medica Beijing University of Chinese Medicine Beijing P.
