ITS sequence analysis used for molecular identification of the Bupleurum species from northwestern China.
Radix Bupleuri (Chaihu), a famous Traditional Chinese Medicine, is derived from the dried roots of Bupleurum chinense DC. and B. scorzonerifolium Willd. But nowadays, other nine species and varieties from genus Bupleurum are also used as Radix Bupleuri in northwestern China. The authentic identification of dried roots of B. chinense and B. scorzonerifolium, however, is difficult to just base on the appearance and morphology. A molecular genetic method was developed to help discriminate the original species of Radix Bupleuri. The ITS sequences ( approximately 600 bp) were amplified by the PCR technique from genomic DNA isolated from all the collected samples. According to analyzing the information given by ITS sequences, the conclusion can be made that ITS sequence could serve as markers for authentication of Radix Bupleuri.
