The therapeutic effect on HCl/ethanol induced gastric injury of Gardenia jasminoides (JXGJ-1 and JXGJ-2) were determined by a animal model. JXGJ-2 group reduced area of its gastric injury as compared to the control group, JXGJ-2 also helped in decreasing the gastric secretion volume results raised in pH value. The NO contents in serum, heart, liver, kidney and stomach of JXGJ-2 group were more than JXGJ-1 and control groups. JXGJ-2 reduce cytokine levels as compared to JXGJ-1 and control group. The serum and gastric tissue SOD, GSH-Px, GSH levels in JXGJ-2 treated mice were higher than JXGJ-1 treated and control mice, but the MDA, PC levels showed the crosscurrents, these levels were close to normal mice. Gardenia jasminoides could increase the occludin, EGF, EGFR, VEGF, IκB-α, nNOS, eNOS, Cu/Zn-SOD, Mn-SOD, CAT, GSH-Px (GSH1) mRNA and protein expressions and decrease the p38MAPK (p38), NF-κB, Bcl-2, COX-2, iNOS expressions in gastric tissues unlike to the control mice, JXGJ-2 had much better effect than JXGJ-1. JXGJ-1contained the higher genipin gentiobioside and gardenoside, they might be the key components of gastric injury inhibition. Gardenia jasminoides had a remarkable effect on gastric injury, and they were derived from two important components of genipin gentiobioside and gardenoside.
