Use of DNA barcoding to identify Chinese medicinal materials
基于DNA barcoding（条形码）技术的中药材鉴定

To identify biological species, DNA barcoding as a new technique is developed. DNA barcoding sequences from a standardized and agreed-upon position in the genome are very short relative to the entire genome and they can be obtained reasonably quickly and cheaply, which attracted more than 130 organizations from 40 countries in the globe. This paper reviews the appearance and development of DNA barcoding. Simultaneously, we study the methods, stepwise technique map and key questions of DNA barcoding which was used to identify Chinese medicinal materials. In conclusion, DNA barcoding has a good prospect in authentication of Chinese medicinal materials.
