In order to accurately identify ginseng species (Panax spp.) that grow naturally in some Northern provinces of Vietnam, we collected 30 natural ginseng samples and used nuclear genetic region (ITS-rDNA) for current analysis. The success rate for nuclear genomic region PCR (ITS-rDNA) amplification is 100%. The bidirectional sequence read success rate obtained from the PCR product was 100%, with a nucleotide sequence length of 588 bp. Based on the analysis of ITS-rDNA region results, the samples of ginseng species from Tuyen Quang and Cao Bang provinces have a close relationship with Panax notoginseng (MLBS = 100%), while the samples of ginseng species from Ha Giang and Yen Bai provinces have a close relationship with P. stipuleanatus (MLBS = 99%).
