  • Korean wild and forest cultivated ginseng has long been accepted as high medicinal values compared to field cultivated ginseng. Owing to the high price of Korean wild ginseng, Chinese wild and forest cultivated ginseng were smuggled and sold as Korean wild and forest cultivated ginseng. Therefore, an efficient method is required to distinguish Korean ginseng from Chinese ginseng. Microsatellites, simple sequence repeats (SSRs), are highly polymorphic loci present in DNA that consist of repeating units of base pairs. Thus SSR markers are highly advantageous for detection of small genetic variances of intra-species. In the present study, we constructed a microsatellite-enriched genomic library from South Korean wild Panax ginseng. After sequence analysis of 992 randomly picked positive colonies, 126 (12.7%) of the colonies were found to contain microsatellite sequences, and 38 primer pairs were designed. By polymorphism assessment using 36 primer pairs, 4 primers (PG409, PG450, PG491, and PG582) were shown to be polymorphic to distinguish the South Korean ginseng from the Chinese ginseng. These 4 microsatellite markers will provide powerful tools to authenticate South Korean ginseng from Chinese ginseng.

  • The objective of this study was to assess genetic diversity among 6 different wild ginseng populations from New York, Kentucky, North Carolina, Pennsylvania, Tennessee and Virginia, and to compare these wild populations to one cultivated population. RAPD markers were used to estimate the genetic difference among samples from the 7 populations. The 64 random primers were screened, and 15 primers were selected which exhibited the 124 highly reproducible polymorphic markers. The ratio of discordant bands to total bands scored was used to estimate the genetic distance within and among populations. Multidimensional scaling (MDS) of the relation matrix showed distinctive separation between wild and cultivated populations. The MDS result was confirmed using pooled chi-square tests for fragment homogeneity. This study suggests that RAPD markers can be used as population-specific markers for American ginseng.

  • Background: Ginsenosides are the major effective ingredients responsible for the pharmacological effects of ginseng. Malonyl ginsenosides are natural ginsenosides that contain a malonyl group attached to a glucose unit of the corresponding neutral ginsenosides. Methods: Medium-pressure liquid chromatography and semipreparative high-performance liquid chromatography were used to isolate purified compounds and their structures determined by extensive one-dimensional- and two-dimensional nuclear magnetic resonance (NMR) experiments. Results: A new saponin, namely malonyl-ginsenoside Re, was isolated from the fresh flower buds of Panax ginseng, along with malonyl-ginsenosides Rb1, Rb2, Rc, Rd. Some assignments for previously published $^1H$- and $^{13}C$-NMR spectra were found to be inaccurate. Conclusion: This study reports the complete NMR assignment of malonyl-ginsenoside Re, $Rb_1$, $Rb_2$, Rc, and Rd for the first time.

  • Background: Panax ginseng has a wide range of biological activities including anti-inflammatory, antioxidant, and immunomodulatory functions. Wild ginseng cambial meristematic cells (CMCs) were obtained from P. ginseng cambium. This study examined the protective mechanism of wild ginseng CMCs against $\small{D}$-galactosamine (GalN)-induced liver injury. GalN, a well-known hepatotoxicant, causes severe hepatocellular inflammatory damage and clinical features similar to those of human viral hepatitis in experimental animals. Methods: Hepatotoxicity was induced in rats using GalN (700 mg/kg, i.p.). Wild ginseng CMCs was administered orally once a day for 2 wks, and then 2 h prior to and 6 h after GalN injection. Results: Wild ginseng CMCs attenuated the increase in serum aminotransferase activity that occurs 24 h after GalN injection. Wild ginseng CMCs also attenuated the GalN-induced increase in serum tumor necrosis factor-${\alpha}$, interleukin-6 level, and hepatic cyclooxygenase-2 protein and mRNA expression. Wild ginseng CMCs augmented the increase in serum interleukin -10 and hepatic heme oxygenase-1 protein and mRNA expression that was induced by GalN, inhibited the increase in the nuclear level of nuclear factor-kappa B, and enhanced the increase in NF-E2-related factor 2. Conclusion: Our findings suggest that wild ginseng CMCs protects liver against GalN-induced inflammation by suppressing proinflammatory mediators and enhancing production of anti-inflammatory mediators.

  • 산삼과 인삼의 세포주를 확립하고, 배양을 통하여 세포성장 및 탄소원 소모 경향과 이들이 생산하는 생리활성물질의(ginsenoside) 생성 특성을 비교 분석하였다. 세포주는 직접 산삼(KM2, KM3, KM5의 뿌리) 및 재배인삼(포천, 홍천, 영주, 무주와 금산에서 재배된 시료)으로부터 callus를 유도하고 장기간 배양하여 확립하였다. 산삼과 재배인삼 세포배양 결과 나타난 특성을 비교해 보면, specific growth rate($\mu$, day-1)는 각각 0.067과 0.035로서 산삼유래의 KM5 세포가 약 2배 정도 빨랐고, 반면에 ginsenoside 생성속도는 각각 0.53과 2.53 mg/L day로 재배인삼 세포에서 약 5배 더 높게 나타났다. 그런데 sugar consumption rate는 각각 1.51과 1.54 g/L any로 비슷한 수준으로 나타났는데, 이러한 결과들을 고찰해 볼 때, 기초 세포배양 조건에서는 KM5 보다 재배인삼인 KE세포에서 ginsenoside 생합성 대사가 더욱 활발하게 이루어지고 있음을 알 수 있었다.

  • Wild Korean ginseng has been recognized as highly precious medicine since ancient times. Nowadays, the population of wild ginseng in the forest of Korean peninsula is very rare due to indiscreet harvest. In this work, we investigated the plant regeneration via somatic embryogenesis from embryogenic callus of old wild ginseng (more than 50 years-old) and compared the features of plants regenerated from 5-years old and 50 years-old ginseng. Induction of embryogenic callus from adventitious roots of 50 year-old wild ginseng required 83 weeks of culture, but only 10 weeks were sufficient for 5 year-old ginseng. Height and width of plants derived from the old wild ginseng was smaller and slender compared to the plantlets derived from 5 year-old ginseng. Total chlorophyll contents was 2-6 time lower in plantlets regenerated from 50 year-old wild ginseng than those from 5 year-old ginseng, but anthocyanin content was higher in 50 year-old ginseng. Our results revealed that plants regenerated from old wild ginseng have different morphological and physiological characters probably due to age-dependent phenomenon.

  • Background: The aim of this study was done to identify whether mass produced wild ginseng culture broth prepared from cultivated wild ginseng roots could have an application in enhancing the agricultural utility value of leafy vegetables. Methods and Results: Leafy vegetables Lactuca sativa and Brassica juncea were treated with wild ginseng culture broth. Plants were examined and treatment (100 ㎖) applied twice a week over an eight week period. Total phenolic and flavonoid content of treated plants was then measured. Wild ginseng culture broth treatment resulted in phenolic and flavonoid content of 0.40 mg·GAE/㎖ and 0.36 mg·QE/㎖, respectively in L. sativa. When treated with wild ginseng culture broth, free radical scavenging ability was found to be higher in both L. sativa and B. juncea whereas antimicrobial activity was found to be higher in B. juncea (625 ㎍/㎖) than in L. sativa. Inorganic element analysis of L. sativa and B. juncea showed that Ca and Mg were higher in the wild ginseng broth treatment group, whereas harmful elements such as As were reduced. Conclusions: Rather than discarding the wild ginseng culture broth, it can be used as a fresh biomaterial by reprocessing it as agricultural products that can promote growth and improve functionality in plants.

  • This study was aimed (i) to develop an effective method for the purification of ginsenosides for industrial use and (ii) to compare the distribution of ginsenosides in cultured wild ginseng roots (adventitious root culture of Panax ginseng) with those of red ginseng (steamed ginseng) and white ginseng (air-dried ginseng). The crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng were obtained by using a 75% ethanol extraction combined with ultrasonication. This was followed sequentially by AB-8 macroporous adsorption chromatography, Amberlite IRA 900 Cl anion-exchange chromatography, and Amberlite XAD16 adsorption chromatography for further purification. The contents of total ginsenosides were increased from 4.1%, 12.1%, and 11.3% in the crude extracts of cultured wild ginseng roots, red ginseng, and white ginseng to 79.4%, 71.7%, and 72.5% in the final products, respectively. HPLC analysis demonstrated that ginsenosides in cultured wild ginseng roots were distributed in a different ratio compared with red ginseng and white ginseng.
