Jinsu Gil,Yi Lee,Yurry Um,Jae Kyung Byun,Chan Moon Chung 한국약용작물학회 2017 한국약용작물학술대회 발표집 Vol.2017 No.05
Background : Panax ginseng C.A. Meyer is a representative medicinal plants and it has been used in traditional medicine because the plant have many effective component such as saponins. To obtain a wild-cultivated ginseng (WCG) which is similar to wild ginseng (WG), this method usually performed in a mountain using seeds or seedlings of cultivated ginseng (CG) and WG. WCG is very expensive because it is difficult to cultivate. However, systematic cultivation method have not been developed compared to their high added value. Furthermore, very high price of WCG caused the problem that Panax notoginseng or Panax quinquefolium are sold as WCG in Korean market. This is concerned as a serious problem to consumers. In this study, we analyzed the agronomic and growth characteristics of the WCG cultivated in Korea. Methods and Results : We examined the WCG that was collected and sold by regional groups at the Korean market. The root age, growth conditions, and quality level of the cultivated WCG were confirmed. WCG samples were collected from five areas in Korea (Bucheon, Cheongju, Hoengseong, Judeok and Ulsan). The main root diameter, root shape index, rhizome length, and root weight showed high level of variation and they did not form annual rings. Conclusion : Agronomic and growth characteristics of WCG showed high variations according to cultivating regions.

Background : Wild-cultivated ginseng (WCG) prices are very different according to root ages. Generally, two methods are used to discriminate the root ages of Panax ginseng C.A. Meyer. The first method is the yearly determination method by the ring dyeing method, and the second method is the confirmation the number of stem vestiges in the rhizome. In this study, we analyzed the agronomic and growth characteristics of the WCG cultivated in Korea. In this study, to determine the appropriate root ages discrimination method for the determination of the root ages of WCG, the root ages of WCG and cultivated ginseng was examined. Methods and Results : We examined the cultivated ginseng (CG) and WCG that was collected and sold by regional groups at the Korean market. WCG does not form annual rings, which are clear and regular in wild ginseng. Therefore, it is impossible to identify the age of WCG by using the annual growth rings staining method. However, the age can be estimated by determining the number of stem vestiges in the rhizome. Conclusion : From the results of the Study on identification of root age for quality evealuation in WCG in Korea. Appropriate root ages discrimination method of WCG was confirmation the number of stem vestiges in the rhizome.
Analysis of Phylogenetic Relationship from Angelica gigas collected in Korea using RAPD Markers

Angelica gigas, also called Dang Gui or Korean Angelica, is a major medicinal herb used in Asian countries such as Korea, Japan and China. In Korea, we are using the roots of A. gigas., but, they are using Angelica sinensis in China and using Angelica acutiloba. in Japan to obtain many active constituents such as dercursin, decursinol angelate, nodakenetin, nodakenin, umbelliferone, β-sisterol, or α-pinene. The plants of the Angelica family are used to improve gynecological health. The biggest problem in the cultivation of A. gigas is bolting. If the bolting occurs, A. gigas can not be used as a medicinal component because the roots are lignified. In this study, 11 A. gigas genetic resources in Korea; 1. Hwangje variety, 2. Sungwoo Jongmyo company, 3. Bonghwa No. 1, 4. Bonghwa No. 2, 5. Bonghwa No. 3, 6. Bonghwa No. 4, 7. Jechun local variety, 8. Jirisan local variety, 9. Manchu variety in Eumseong, 10. Manchu variety in Bonghwa, 11. Jinbu local variety, were collected and performed phylogenetic analysis using RAPD molecular markers.
Analysis of Phylogenetic Relationship of Codonopsis lanceolata Cultivated in Korea using RAPD Makers
Jinsu Gil,Serim Kim,Yurry Um,Seon-Woo Cha,Yi Lee 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07
Codonopsis lanceolata is used as a natural medicine or vegetables. It originates in East Asia such as Korea, Japan and China. Similar to Panax ginseng, C. lanceolata contains saponins as effective components. C. lanceolata is cultivated in many regions of South Korea. But, no variety was developed yet and the origin discrimination in the distribution market of C. lanceolata became a problem. In this study, we collected 20 C. lanceolata regional groups; Hoengseong, Wonju, Samcheok, Chuncheon, Pyeongchang, Hongcheon, Yongin, Yangpyeong, Danyang, Chungju, Bonghwa, Ulleung, Yeongju, Sancheong, Muju, Gwangyang, Sinan, Hwasun, Jeju-si and Seogwipo-si, and tested the genetic relationship using RAPD molecular markers. The genomic DNA was extracted using CTAB and the RAPD analysis was performed using 32 primers of Operon Technologies. NTsys-PC program was used for the phylogenetic analysis of the data.
