Identification System and Perspective for DNA Barcoding Traditional Chinese Materia Medica
中药DNA条形码鉴定体系及研究方向

DNA barcoding in Traditional Chinese Materia Medica has developed rapidly in recent years,which accelerates the progress of standardization in identifying Traditional Chinese Materia Medica.Chen et al.first proposed that ITS2 locus can be used as the standard barcode for identifying medicinal plant species based on an extensive study on DNA barcoding in Traditional Chinese Materia Medica.Meanwhile,the systems for barcoding medicinal plants based on a two-locus combination of ITS2+psbA-trnH and for authenticating medicinal animals based on COI+ITS2 have been established,providing a basis for the development of DNA barcoding in Traditional Chinese Materia Medica.In this review,we summarize the establishment of the system for barcoding Traditional Chinese Materia Medica,including the selection and determination of DNA barcodes,the identification process of DNA barcoding in Traditional Chinese Materia Medica and building the database system of DNA barcoding in Traditional Chinese Materia Medica.Moreover,we describe the perspective for further research on DNA barcoding in Traditional Chinese Materia Medica.
