Figure 1

High-performance liquid chromatogram of the watery extract from Coptis chinensis (Franch). Blue line represents the HPLC chromatogram of mixed standard compounds (MSC); 1: coptisine, 2: palmatine, 3: berberine. Note that coptisine, berberine, and palmatine are the main components of the CRE. ACD/ChemSketch (http://www.acdlabs.com/resources/freeware/chemsketch/) was used to design chemical structures.
