[Determination of 30 bile acids in the bile of and using ultra-high performance liquid chromatography-triple quadrupole mass spectrometry].

Bile acids (BAs), the primary components of bile, play significant roles in sugar, lipid, and cholesterol metabolism. Normal BA metabolism maintains a dynamic equilibrium by regulating gut microbiota to effectively protect the liver and intestines, thereby sustaining overall health. Conversely, abnormal BA metabolism can cause intestinal tissue and liver damage, disruption of enterohepatic circulation homeostasis, dysbiosis of gut microbiota, and gastrointestinal and hepatic diseases.
