A Pharmacodynamic Research on Chromone Glucosides of Fangfeng

OBJECTIVE: To investigate the pharmacological activity of prim-O-glucosylcimifugin and 4'-O-beta-D-glucosyl-5-O-methylvisamminol con tained in Fangfeng. METHODS: Analgesic, antipyretic and antiinflammatory effects were assessed using the models of yeast-induced rat fever, acetic acidinduced peritoneal pain thermalpain, and dimethylbenzol-induced mouse ear edema. RESULTS: Prim-O-glucosylcimifugin and 4'-O-beta-D-glucosyl-5-O-methylvisamminol could reduce the body temperature of rats in a model of yeast-induced fever. Both components could decrease the spasm action induced by peritoneal injection of acetic acid, increase the pain-threshold in a thermal-pain model, relieve the mouse ear edema caused by dimethybenzol and significantly inhibit ADP-induced platelet aggregation. CONCLUSION: Prim-O-glucosylcimifugin and 4'-O-beta-D-glucosyl-5-O-methylvisamminol have significant analgesic, antipyretic, anti-inflammatory and anti-platelet aggregation actions.
