Abstract: Chinese medicine is a precious resource and plays an important role in disease treatment and health care in our daily life. However,in recent years,the safety incidents from using traditional Chinese medicines due to inappropriate identification methods have repeatedly occurred,which has brought huge challenges to the clinical application of traditional Chinese medicines. The traditional identification method is that traditional Chinese medicine pharmacists identify Chinese medicinal materials via applying their long-term accumulated experiences. Although the method is getting more and more perfect,it is still subjective and undeniably has its limitations. With the development of science and technology,new technologies and new methods promote the development of the identification of traditional Chinese medicines;the traditional identification methods can be reasonably combined with modern identification methods,and more accurate and scientific identification of Chinese herbal medicines can be achieved. The recent development of high-throughput sequencing technology has provided a favorable platform for the development of molecular marker technology and a more accurate and reliable means for the identification of Chinese herbal medicines. Currently,RAPD,AFLP,RFLP,and SSR are the several molecular markers most widely used,each of them has its own advantages and disadvantages. SSR refers to a piece of DNA consisting of multiple repeated units of 1-6 nucleotides in the genome. The SSR marker characterizes of high specificity,fine repeatability,reliable results,simple operation,and low DNA requirements,and thus plays an increasingly important role in the variety identification of Chinese medicinal materials,plant germplasm identification,genetic map construction,and genetic diversity analysis. The application of SSR marker technique in the identification of traditional Chinese medicine in recent years is briefly summarized here,aiming at providing a reference for the further application of this technique in the identification of traditional Chinese medicine.
