Identification of Bupleuri Radix and its adulterants by DNA barcoding
【Abstract】Objective To identify the authenticity of Bupleuri Radix in the market of Hebei province. Methods In this research, the ITS2 sequence of 28 samples of Bupleuri Radix that were bought from the market in Hebei province was amplified by PCR, and the sequence of seven samples was downloaded from Gen Bank. Aligner Codon Code software was used for sequence alignment, the MEGA6. 0 analysis was used to calculate the K2P distance, and the mutation sites of each sequence was analyzed. Results Among the 28 Bupleuri Radix samples, there were 21 samples for Bupleurum chinese, 3 for Bupleurum smithii, and 4 for the false. Conclusion ITS2 sequence can be used as an effective method to identify the authenticity of BupleuriRadix, it is great value to the medicine market standard and the clinical medication safety.
