The present study aims to investigate the therapeutic actions of Jinlingzi powder and its extracted components and theirs treatment mechanism on the acetic acid induced-gastric ulcer in rats.

The gastric ulcer model was induced by the administration of acetic acid in rats (84 male).

Jinlingzi powder water decoction, its polysaccharide, and nonalkaloid and alkaloid components were used to investigate the therapeutic actions on the acetic acid induced-gastric ulcer by measuring the related pharmacy and pharmacodynamic factors, including ulcer index, ulcer area, ulcer healing rate, interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), neurotensin (NT), platelet activating factor (PAF), thromboxane B2 (TXB2), and vascular endothelial growth factor (VEGF) in rat serum, acetylcholinesterase (AChE) in brain tissue, prostaglandin E2 (PGE2), and basic fibroblast growth factor (bFGF) in gastric tissue.

Among the various groups, Jinlingzi powder and the nonalkaloid components caused significant changes in IL-8, TNF-α, NT, PAF TXB2, and VEGF values in the serum.

The AChE content in the rats’ brain tissue was also reduced after using Jinlingzi powder and the nonalkaloid components.

Additionally, Jinlingzi powder and the nonalkaloid components considerably affect the amount of PGE2 and bFGF in a rat’s stomach tissue.

Therefore, Jinlingzi powder and the nonalkaloid components can effectively inhibit neutral neutrophil activation, prevent capillaries thrombosis, and protect gastric mucosa.

Thus, the nonalkaloid components of the Jinlingzi powder play a key role in the treatment of gastric ulcer.
