OBJECTIVE: Chemical composition of precipitate was researched when Huanglian-Huangqin was decocted. METHOD: Ployamide column chromatography, TLC and TOF-MS were used. RESULT: The precipitate contains berberine, palmatine, jalrorrhizing, epiberberine, copticine, baicaling and wogonoside. CONCLUSION: The precipitate is effective composition in Chinese medical decoction. The research provides new data on medical effects of Huanglian-Huangqin couples.
