Background: In Korea, 6-year-old ginseng root is economically more important than 4 or 5-year-old roots. In general, the root age is determined by counting the number of stem vestiges. However, this method does not accurately estimate ginseng root age. Methods and Results: In this study, the stem vestige counting method was used to survey a total of 18,395 fresh ginsengs cultured in 2014, and 2015, to determine the accuracy of this method. The proportion of 6-year-old roots, with more than four stem vestiges, was 46.1% in 2014. For the cultivar Chunpoong cultivated in Eumseong and Goesan countries in 2015, the proportion of more than four stem vestiges was 55.9%, and 43.5%, respectively. The proportion of more than four stem vestiges for the Gumpoong cultivated in Eumseong and Yangpyeong countries was 67.0%, and 35.1%, respectively, whereas that for the cultivar Yunpoong was 36.0% and 61.0%, respectively. Moreover, it was confirmed that differences in the levels of Rg1 will enable root age determination. Conclusions: Root age determination by the stem vestige test was found to differ depending on the environmental and cultivation conditions. To determine the age of ginseng roots, a comprehensive method, such as counting stem vestiges and evaluating differences in ginsenoside levels, should be applied.

문제 정의
Moreover, the existing methods have focused on the root age identification of rhizomes while lacking results for red ginseng. Therefore, this study sought to verify whether the stem vestige method was suitable for root age identification of red ginseng. Furthermore, this study analyzed whether the contained volume of specific ginsenoside in particular varieties enabled the root age identification.
제안 방법
4, 5 and 6-year-old ginsengs grown in the Biology Resource Research Center of KGC were cultivated. For the samples used in the analysis, the number of stem vestige according to the root age was clear and 60 g, 80 g, and 100 g were used for the 4, 5, and 6-year-old ginseng weights, respectively.
Therefore, this study sought to verify whether the stem vestige method was suitable for root age identification of red ginseng. Furthermore, this study analyzed whether the contained volume of specific ginsenoside in particular varieties enabled the root age identification.
The UPLC test was conducted using a ACQUITY UPLC system (Waters, Millford, MA, USA). The chromatographic separation was carried out on ACQUITY BEH C18 column (2.
This study compared ginseng plants by region, cultivar and the changes in the number of stem vestiges before and after the manufacture of red ginseng, in order to confirm the accuracy of age determination test of the current stem vestige.
대상 데이터
9,979 fresh ginseng (Panax ginseng C. A. Meyer) roots used in this study were collected from different geographical regions in South Korea from 2014 to 2015 (Table 1). In 2014, stem vestige number was surveyed in 7,597 violet-stem Landrace of 6-year-old fresh ginseng and was again surveyed on these plants after their manufacture into red ginseng.
In the same year, the Rural Development Administration (RDA) surveyed 220 Chunpoong, 100 Yunpoong, and 100 Gumpoong cultivars. All the materials used in this study are 6-year-old fresh ginseng.
데이터처리
The results were analyzed via Student’s t-test using the SAS sofware package (SAS v9.2, SAS Institute Inc., Cary, NC, USA), and the difference was proven to be statistically significant when the p-value was under 0.05.
이론/모형
The root age of ginseng was measured by adding 2 to the stem vestige in a root according to the Lee et al. (2007) method.
성능/효과
5%. The proportion of root with 4 or more stem vestiges after their manufacture into red ginseng was 70.8%, and the proportion of root with 3 or less stem vestiges was 29.2% (Table 2).
However, the content of 5-year-old was lower than that of 4-year-old. While it was difficult to ascertain the identity of ginseng based on the ginsenoside content by root age, this study revealed that root age could be identified using Rg1 content.
후속연구
Future research should further verify the possibility of root age identification using ginsenoside content based on the region of origin or root age. However, root age identification inferred from the total Rg1 content was not consistent these results were in line with those reported by Han et al.
