The establishment of a DNA barcode database at the regional scale and assessments of the utility of DNA barcodes are crucial for conservation biology and for the sustainable utilization of biological resources. Schisandraceae is a small family consisting of ca. 45 species. It contains many economically important species, such as Schisandra chinensis, which is widely used as a source in tonic beverages and in oriental medicine. In Korea, three species, S. chinensis, S. repanda, and Kadsura japonica, are distributed. We evaluated the level of variation of the DNA sequences of rbcL, matK, and the ITS regions from 13 accessions representing the distributional range of the three species. The three DNA barcode regions were easily amplified and sequenced. The minimum values of the interspecific genetic distances among S. chinensis, S. repanda, and K. japonica either separately or in combination are 4- to 23-fold higher than the maximum value of the intraspecific distance, showing that there is a clear DNA barcoding gap in the regions for Korean Schisandraceae. Phylogenetic analyses of the three DNA barcode regions, separately and simultaneously, indicate that all of the DNA barcode regions are useful for identifying a species of Schisandraceae in Korea. The distinctiveness of the three species of Schisandraceae was also supported at the species level when Chinese and Japanese populations were added. The results of this study indicate that three concatenated regions constitute the best option for DNA barcoding in Schisandraceae in Korea.

한국산 나문재속 식물에 대한 계통학적 유연관계를 밝히고, 분자계통학적 연구를 통해 나문재속 종간 유연관계를 확인할 수 있는 분자마커를 찾아내기 위해 연구를 수행하였다. 핵 리보솜 DNA ITS와 엽록체 DNA matK, psbA-trnH 그리고 trnL-trnF를 분자마커로 사용하였다. ITS 영역은 칠면초와 해홍나물 그리고 해홍나물과 방석나물을 구분하지 못하였다. psbA-trnH와 trnL-trnF 영역의 염기서열은 칠면초와 방석나물을 구분하지 못하였다. 그러나 4종의 분자마커 영역을 조합하여 분석한 결과 나문재속 식물 5종이 각각 독립적인 계통을 형성하는 것을 확인하였다. 따라서 나문재속 계통관계 분석을 위해서 여러 개의 분자마커 조합이 유용할 것으로 판단된다. 나문재속 내 분류군 간의 계통관계를 명확히 밝히기 위해 차후에 좀 더 많은 생태학적, 형태학적 자료를 조사해야 할 것으로 보인다.

Objectives : Official Arisaematis Rhizoma is described only three species, Arisaema amurnse, Arisaema erubescens, and Arisaema heterophyllum, in national Pharmacopoeia. However, other Arisaema species, Arisaema ringens, Arisaema takesimense and Arisaema serratum, also have been distributed as an inauthentic Arisaematis Rhizoma in the herbal market. To develop a reliable molecular authentication method for Arisaematis Rhizoma in species level, we analyzed DNA barcode regions using six Arisaema species. Methods : Thirty-eight samples of six Arisaema plants species (A. amurense, A. amurense f. serratum, A. heterophyllum, A. takesimense, and A. serratum) were collected from different habitate and nucleotide sequences of DNA barcode regions (rDNA-ITS, matK, and rbcL gene) were analyzed after PCR amplification. The species-specific sequences and phylogenetic relations were estimated using entire sequences of three DNA barcodes based on the analysis of ClastalW and UPGMA, respectively. Results : The comparative analysis of DNA barcode sequences were revealed inter-species specific nucleotides to distinguish the medicinal plant of Arisaema Rhizoma in species levels excluding between A. amurense and its subspecies (A. amurense f. serratum) and A. takesimense and A. serratum, respectively. However, we obtained sequence differences enough to discriminate authentic and inauthentic Arisaematis Rhizoma. Therefore, we suggest that these SNP type molecular genetic markers were an reliable method avaliable to identify official herbal medicines. Conclusions : These marker nucleotides could be useful to identify the official herbal medicines by providing definitive information that can identify original medicinal plant and distinguish from inauthentic adulterants and substitutes.

Objectives : The origin of Breeae Herba (So-gye) and Cirsii Herba (Dae-gye) is differently prescribed in Korean and Chinese modern pharmacopoeia. Since the similar morphological characteristics and chaotic plant names, moreover, the aerial part of Carduus crispus have been used as the Cirsii Herba. To develop a reliable method for correct identification of these herbal medicines and to evaluate the genetic relationship of these closely related plant species, we analyzed sequences of DNA barcode regions. Methods : Thirty-one samples of 6 medicinal plants (B. segeta, B. setosa, C. japonicum var. maackii, C. setidens, C. chanroenicum, and C. crispus) were collected from different habitate and nucleotide sequences of DNA barcode regions (rDNA-ITS, matK, and rbcL) were analyzed after amplification using appropriate primers reported in previous studies. The nucleotides of species-specific authentic marker and phylogenetic relations were estimated based on the entire sequences of DNA barcodes by the analysis of ClastalW and UPGMA, respectively. Results : In comparative analysis of DNA barcode sequences, we obtained specific nucleotides to discriminate the medicinal plant of Breeae/Cirsii Herba in species level and evaluated the phylogenetic relationship of these species. Futhermore, we identified distinct marker nucleotides enough to authenticate respective species. These sequence differences at corresponding positions were avaliable genetic markers to determine the botanical origins of Breeae Herbal as well as Cirsii Herba. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by providing of definitive information that can identify each plant species and distinguish from unauthentic adulterants and substitutes.

Objectives : Pinelliae Tuber has been used as a typical unauthentic herbal medicines. Due to the morphological similarity between Pinelliae Tuber and adulterants, the correct authentication is very difficult. Therefore, we introduced DNA barcode to establish a powerful tool for the authentication of Pinelliae Tuner from adulterants. Methods : To obtain DNA barcode regions, genomic DNA was extracted from nineteen specimens of Pinellia ternata, Pinellia pedatisecta, Pinellia tripartita, and Typhonium flagelliforme, and matK and rbcL genes were amplified. For identification of species specific sequences and analysis phylogenetic relationship, a comparative analysis were performed by the ClastalW and UPGMA based on entire sequences of matK and rbcL genes, respectively. Results : In comparison of two DNA barcode sequences, we elucidated the phylogenetic relationship showing distinct four groups depending on species and identified 40 and 20 species specific nucleotides enough to distinguish each species from matK and rbcL gene, respectively. The sequence differences at the corresponding positions were avaliable genetic marker nulceotides to discriminate the correct species among analyzed four species. These results indicated that phylogentic and comparative analysis of matK and rbcL genes are useful genetic markers to authenticate Pinelliae Tubers. Conclusions : The marker nucleotides enough to distinguish P. ternata, P. tripatrita, P. peditisecta, and T. flagelliform, were observed at 40 positions in matK gene and 20 positions in rbcL gene sequence, respectively. These differences can be used to authenticate Pinelliae Tuber from adulterants as well as discriminate each four species.

Objectives : Araliae Continentalis Radix and Angelicae Pubescentis Radix have been used as the same medicinal name Korean and Chinese traditional medicines, respectively. The authentic Araliae Continentalis Radix is described only the root of Aralia continentalis in the Korean Pharmarcopoeia. However, the dried root of Angelica biserrata, Levisticum officinale, or Heracleum moellendorffii also has been distributed adulterants of Araliae Continentalis Radix. To develop a reliable method for identifying Araliae Continentalis Radix from adulterants, we carried out the analyses of universal DNA barcode sequences.Methods : Four plants species were collected from different habitate and nucleotide sequences of matK and rbcL were analyzed. The species-specific sequences and phylogenetic relationship were estimated using entire sequences of two DNA barcodes, respectively.Results : In comparative analysis of matK sequences, we were identified 104 positions of marker nucleotide for Ar. continentalis, 3 for An. biserrata, 4 for L. officinale and 8 for H. moellendorffii enough to distinguish individual species, respectively. Furthermore, we obtained marker nucleotides in rbcL at 42 positions for Ar. continentalis, 5 for An. biserrata and 2 for H. moellendorffii, but not for L. officinale. The phylogenetic tree of matK and rbcL were showed that all samples were clustered into four groups constituting homogeneous clades within the species.Conclusions : We confirmed that species-specific marker nucleotides of matK sequence provides distinct genetic information enough to identify four species. Therefore, we suggest that matK gene is useful DNA barcode for discriminating authentic Araliae Continentalis Radix from inauthentic adulterants.
