Deciphering the chemical constituents of Shengjiang Xiexin decoction by ultrahigh‐performance liquid chromatography‐quadrupole/orbitrap high‐resolution mass spectrometry and the impact of 20 characteristic components on multidrug resistance‐associated protein 2 in the vesicular transport assay

H]-estradiol 17-β-glucuronide in the vesicles. This was the first systematic investigation of the chemical constituents from Shengjiang Xiexin decoction and the effect of its characteristic components on the transporter. The results offered a basis for further exploring the detoxification mechanisms of this formula and its interactions with other drugs.
