    Polygonatum is a genus placed in the family Liliaceae, distributed throughout the Northern Hemisphere and16 of the species are grown naturally in Korea. In oriental medicine, the rhizomes of Polygonatum have been used as two differentmedicines, Okjuk (Polygonati odorati Rhizoma) and Hwangjeong (Polygonati Rhizoma). However, it is difficult toidentify the morphological and chemical differences between the medicinal groups and thus easy to confuse the one with theother. Therefore, a clear classification standard needs to be established so as to be able to discriminate between them. In thestudy, the morphological characteristics of the plants, Polygonatum spp., were examined. Then, the differences in SNPsamong the DNA sequences of 7 of the Polygonatum spp. and 1 of the Disporum spp. were analyzed by DNA barcoding withrpoC1, rpoB2, matK, and psbA-trnH of the cpDNA region. In the results, three regions, rpoC1, rpoB2, and matK were usefulfor discriminating the species, P. stenophyllum and P. sibiricum. Furthermore, it was possible to discriminate the individualgermplasm within the species by using the combination of the results obtained from rpoB2, rpoC1, and matK.
