The effect of anti-alcoholic gastric ulcer before and after vinegar-processed Yuanhu Zhitong prescription based on spectral-effect relationship.

Abstract

The aim of this study was to screen out the active ingredients of Yuanhu Zhitong prescription (YZP) before and after vinegar processing to play an anti-alcoholic gastric ulcer role through spectrum-effect relationship. First, the fingerprint of 16 batches of YZP was studied using the ultra-high-performance liquid chromatography-quadrupole mass spectrometry detector analysis (UPLC-QDA) method. Second, gastric lesion was induced by anhydrous ethanol. The degree of gastric mucosa injury was evaluated by hematoxylin and eosin staining, and the contents of malondialdehyde and tumor necrosis factor α and superoxide dismutase were detected using the enzyme-linked immunosorbent assay kit. Sixteen batches of YZP were analyzed using the spectrum-effect relationship method. Finally, absorption, distribution, metabolism, and excretion (ADME) was used to evaluate the bioavailability of potential compounds. The results showed that the UPLC-QDA method could successfully establish the fingerprint of YZP. Hematoxylin and eosin staining and biochemical indicators showed that YZP had obvious anti-alcoholic gastric ulcer action. Coptisine chloride, corydaline, berberine chloride, palmatine, imperatorin, and phellopterin were screened out using the spectrum-effect method, and all of them possessed good bioavailability. The results of this study suggest that YZP plays an anti-ulcer role by exerting antioxidant and anti-inflammatory effects through six main active components.
