Abstract:
Objective To study the acute toxicity of total polymethoxyflavones from Bauhinia championii (PMFBC) in mice and its effect on experimental gastric ulcer. Methods The acute toxicity of PMFBC was investigated by Bliss method. Three kinds of gastric ulcer model including indomethacin, ethanol, and water immersion-restraint stress were used to observe the effect of PMFBC in mice. Results The LD50 value of ig administration PMFBC on mice was 1 252.319 mg/kg, which showed acute toxicity; PMFBC had protective effect on three gastric ulcer models, which could significantly reduce the ulcer area of the mice, and had a high inhibition rate. Conclusion PMFBC has obvious inhibition effect on the fomation of gastric ulcer in mice, which can be safty used in a certain dose range.
