OBJECTIVE: To investigate composition principles of Gegen Qin Lian decoction through anti-pyretic experiment. METHOD: Pharmacological effects of different compounds of Gegen Qin Lian decoction according to six hours temperature response index (TRI6) and average top temperature response height (deltaT) after the decoction was given to feverish animal model by inactived bacteria suspension. RESULT: As for reducing six hour temperature response index, Scutellaria baicalensis root was the main effective drug. Pueraria lobata root could enforce the effect while Coptis chinensis rhizome and Glycyrrhiza uralensis root counteracted it. As for reducing average top temperature response height, the Effects of four herbal drugs were the same as for TRI6. CONCLUSION: Of the compounds of Gegen Qin Lian decoction, as to the pharmcological anti-pyretic effects, the best one is the compound of Scutellaria baicalensis and Pueraria lobata roots.
