Ponciretin attenuates ethanol-induced gastric damage in mice by inhibiting inflammatory responses.
    International immunopharmacology, 2017, Volume: 43

    Poncirin (PO) and isosakuranetin (or ponciretin [PT]) are compounds found in fruits of the genus Citrus. They are frequently used in traditional Chinese medicine for the treatment of inflammation and asthma. Therefore, we examined their anti-gastritis effects in vitro and in vivo.. The anti-inflammatory effects of PO and PT were examined using ethanol- or LPS-stimulated KATO III cells. Gastritis was induced in ICR mice via intragastric injection of absolute ethanol. Levels of inflammatory markers were measured by enzyme-linked immunosorbent assay, immunoblotting, and quantitative polymerase chain reaction.. Treatment with PT or PO inhibited the secretion of interleukin (IL)-8 and tumor necrosis factor (TNF) in ethanol- or LPS-stimulated KATO III cells. They also reduced the activation of nuclear factor kappa B (NF-κB). Pre-treatment with PT or PO significantly protected against ethanol-induced hemorrhagic gastritis, characterized by edema, tissue erosions, and mucosal friability in mice. Treatment with PT or PO suppressed ethanol-induced NF-κB activation and the release of TNF, IL-8, and IFN-γ. The protective effect of PT was greater than that of PO and comparable to ranitidine, a positive control.. PT may attenuate ethanol-induced gastritis by inhibiting the infiltration of immune cells, including neutrophils, via the regulation of CXCL4 (or IL-8) secretion and the activation NF-κB.

Protective effects of neohesperidin and poncirin isolated from the fruits of Poncirus trifoliata on potential gastric disease.
    Phytotherapy research : PTR, 2009, Volume: 23, Issue:12

    The effects of Poncirus trifoliata (P. trifoliata) (Ponciri Fructus, PF) extract and its constituents such as neohesperidin and poncirin on gastritis in rats and human gastric cancer cells were investigated. The PF 70% ethanol extracts (1 g) showed approximately 11.38% of acid-neutralizing capacities and cytotoxicity (IC50=85.39 microg/mL) against human AGS gastric cancer cells. In addition, neohesperidin exhibited antioxidant activity (IC50=22.31 microg/mL) in the 1,1-diphenyl-2-picryldydrazyl (DPPH) radical-scavenging assay. Neohesperidin (50 mg/kg) and poncirin (100 mg/kg) significantly inhibited 55.0% and 60.0% of HCl/ethanol-induced gastric lesions, respectively, and increased the mucus content. In pylorus ligated rats, neohesperidin (50 mg/kg) significantly decreased the volume of gastric secretion and gastric acid output, and increased the pH. From these results, it could be suggested that neohesperidin and poncirin isolated from PF may be useful for the treatment and/or protection of gastritis.
