Research Advances of Coptis

YANG Jun-bao et al (School of Life Science, China West Normal University, Nanchong, Sichuan 637002)  
Research development of Coptis resources was reviewed in the aspects of species resource, geographic distribution, biological characters, cell and tissue culture, molecular research and protective measure. Extending in applied scope, increasing in demands, especially excessive gathering medicine herbs had brought serious damage to the species of Coptis and some of the species of Coptis became nearly extinct. Up to now, no effective conservation steps had been taken, thus much more basic studies should be done and some protective measures were proposed.
