The Analyses of Soluble Protein in Rhizoma Coptidis by SDS-PAGE Electrophoresis

ObjectiveThe soluble protein of Coptis deltoidea C.Y.Cheng et Hsiao.、Coptis 0meiensis.、 Coptis teeta Wall.and Coptis chinensis Franch.which come from different region were identified.MethodsProtein electrophoresis technology SDS-PAGE was applied.ResultsThe experiment shows that there were obvious differences between Coptis deltoidea C.Y.Cheng et Hsiao.and Coptis chinensis Franch.、little difference between Coptis omeiensis.and Coptis chinensis Franch.、a little difference between Coptis chinensis Franch.from different region.There was only one weak band in Coptis teeta Wall.ConclusionSDS-PAGE electrophoresis method can identify quality stability of Rhizoma Coptidis.
