Abstract
This invention provides a procedure for authentication of plant and animal materials used as traditional Chinese medicine is described. This method amplifies and detects the discrete and species-specific RFLP patterns in the region of rDNA. The present invention offers a reliable and definite way to identify morphologically similar Chinese medicine, using a minute amount of biological samples. Its application in the authentication of American and Oriental ginsengs is illustrated in detail.
