The Anti-inflammatory and Analgesia Experiment Research of the Extract of Caesalpinia minax Hance

Objective To evaluate the effect of the extract of Caesalpinia minax Hance on mouse ear edema, rat paw swelling and analgesia activity. Methods The inflammatory reaction model of mouse ear edema engendered by overlaying the dimethylbenzene on the auricle and rat paw swelling induced by injecting carrageenin to the toes, pain produced by injecting the glacial acetic acid to abdomen in mouse and hot plate. Results The ethanol extract (8 g/kg) and the chloroform extract(4 g/kg and 8 g/kg) of C. minax depressed the mouse ear edema and inhibited the rat swelling extent obviously. The ethanol extract (4 g/kg and 8 g/kg) and the chloroform extract(4 g/kg and 8 g/kg) of C. minax reduced the stretching times significantly and improved pain threshold. Conclusion The extract of C. minax has notable effect of anti-inflammation and analgesia.
