  • Vesicular-arbuscular mycorrhizae (VAM) fungi naturally colonise American ginseng roots and this relationship is highly beneficial to enhance plant productivity. Our goal was to determine the effect of adding two Glomus species (Glomus etuticatum, G. intraradices) on survival, photosynthetic capacity, growth, morphology and root ginsenoside content of one-year-old American ginseng plants grown in a broadleaf forest. While our study revealed that VAM inoculations significantly affected root morphology and Re ginsenoside content, the survival, photosynthetic capacity and root growth of American ginseng plants were not significantly influenced by VAM inoculations. Surface area and volume of rootlets were 16-25% higher for ginseng grown in VAM-inoculated soil compared to those grown in the control plots. Also, Re ginsenoside content was 18 % higher in YAM-inoculated roots compared to controls.

  • The red ginseng is very popular as a health food. It has been manufactured with raw ginseng by the conventional method. But, the yield of the heaven grade ginseng (the best quality red ginseng) among the whole products is around 5-7%, Therefore, the yield should be improved in order to increase economic returns. In this study, a new model of drying system was developed to improve the yield of heaven grade ginseng from 7% to 15% or more. For this system, temperature and relative humidity were controlled by the feedback control system, and a solenoid valve for steam supply and other variables were controlled by the PC. The special features of this system developed are an image processing system for monitoring the red ginseng during the drying process in the drying chamber, and a cylindrical porous tray for holding ginseng that is rotating with the speed of 0-10rpm in the drying chamber and makes uniform drying of red ginseng possible.

  • Ginseng cultivated and grown naturally under mountainous forest is formally called "Lin-Xia-Shan-Shen" (LXSS) and grown in manual condition is called garden ginseng (GG) according to Chinese pharmacopoeia (2010 edition). Usually the growing condition of LXSS is similar to wild ginseng and mostly used in Chinese folks in ancient times. The antioxidant properties of LXSS with different growing years were evaluated by their inhibitions of thiobarbituric acid-reactive substance (TBA-RS) formation in liver homogenate and 2, 2-diphenyl-1-picrylhydrazyl (DPPH)-radical scavenging activity comparing with those of GG. The inhibitions of different polar extracts (n-butanol and water) of LXSS and GG on TBA-RS formation were also evaluated. The results showed that the antioxidant effects of LXSS were higher than those of GG and the TBA-RS formation inhibition of LXSS with longer growing years were stronger than those with shorter growing years, while the DPPH-radical scavenging activity of LXSS did not show significant difference with the change of the growing year. The results indicated that the inhibitory effect of TBA-RS formation and the DPPH-radical scavenging of LXSS were correlated with the contents of ginsenosides. In adddition, the starch contents of LXSS and GG were determined by micro-amount method with spectrophotometer. It showed that the starch content in GG was higher than that of LXSS whose starch decreased gradually with the growing year.

  • This work was carried out to establish adventitious root culture system in three Panax species (wild-grown P. ginseng, P. quinquefolium, and P. japonicum) to analyze their ginsenoside productivity. Adventitious roots were induced directly from segments of seedlings after cultured on MS(Murashige andSkoog 1962) solid medium containing 3.0 mg/l IBA. Omission of $NH_4NO_3$ from the medium greatly enhanced both the frequency of adventitious root formation and number of roots per explants in all the three Panax species. However, elongation of post-induced adventitious roots was enhanced on medium with $NH_4NO_3$. Two-step culture protocol: $NH_4NO_3$-free medium for first two weeks of culture, followed by $NH_4NO_3$ containing medium for further 4 weeks, greatly enhanced the fresh weight increase of adventitious roots in all the three ginseng species. The fresh weight of adventitious roots was high in P. quinquefolium and low in P. ginseng, followed by P. japonioum regardless of the composition of medium. Pattern and content of ginsenosides in adventitious roots differed among the three Panax species. Total ginsenoside content of adventitious roots in P. quinquefolium, P. ginseng, and p. japonicum was 8.03, 15.7 and 1.2 mg/g dry weight, respectively. Among the three speices, adventitious roots in P. quinquefolium produced hig-hamount of ginsenosides. The pattern of ginsenoside fractions between P. ginseng and P. quinquefolium was similar but the amount of ginsenoside differed between the two, While, in P japonicum, total ginsenoside content was very low and some ginsenosides such as ginsenoside Rb2 and Rf were not detected. Conclusively, we demonstrate that same culture condition was required for induction and elongation of adventitious roots of three ginseng species but growth of adventitious roots and their ginsenoside production were different among them.

  • 고령사회에서 노년기 건강의 큰 문제로 대두되고 있는 골다공증은 특히 폐경 후 여성들에게서 가장 그 발생빈도가 높게 나타났으며, 현재 골다공증 예방 및 치료에 사용되고 있는 약제는 대부분 골흡수 억제제로써 진행된 골소실을 회복 시킬 수는 없기 때문에 골형성 증가를 통한 골다공증 예방과 치료에 관한 연구가 활발히 이루어지고 있다. 산양삼(cultivated wild Panax ginseng, CWP)에 대한 연구는 다수가 원기회복, 자양강장 및 면역증강 효과 등에 대한 것이나 골대사에 미치는 영향에 대한 연구는 거의 없는 실정이다. 이에 본 연구에서는 산양삼 추출물이 조골세포에서 골관련 유전자 발현에 미치는 영향을 확인함으로써 골다공증 예방 및 치료 효과를 갖는 천연 소재로의 활용 가능성을 검토하고자 하였다. 산양삼 추출물 처리가 조골 세포의 증식에 미치는 영향을 알아보기 위해 MTT assay를 실시하였고, MC3T3-E1 세포생존률은 FBS가 첨가되지 않은 배양액만 처리한 대조군과 산양삼 추출물을 처리한 실험군 모두에서 동일한 수준으로 나타났으며 이로써 산양삼 추출물의 안전성을 확인할 수 있었다. 또한 산양삼 추출물을 처리한 실험군과 대조군과의 세포증식률을 비교하였을 때 산양삼 추출물 50 ㎍/mL 농도 처리군에서 유의적으로 세포증식이 촉진되었으며 25 ㎍/mL과 100 ㎍/mL 농도 처리군에서도 대조군보다 높은 경향을 나타내었다. 산양삼 추출물이 조골 세포의 활성에 미치는 영향을 알아보기 위해 조골세포의 분화초기 표지인자인 ALP활성을 측정하였으며 그 결과 모든 산양삼 추출물 처리군이 대조군과 비교하여 유의적으로 높은 활성을 나타내었으며 특히 산양삼 추출물 50 ㎍/mL 농도 처리군에서 가장 높은 활성을 나타내었다. 산양삼 추출물의 농도에 따른 석회화 형성도를 확인하기 위해 무기질화된 세포의 기질을 alizarin red로 염색하였고 산양삼 추출물을 처리한 실험군과 대조군과의 석회화 형성도를 비교하였을 때 산양삼 추출물 50 ㎍/mL 농도 처리군에서 유의적으로 석회화 형성이 촉진되었으며 25 ㎍/mL과 100 ㎍/mL 농도 처리군에서도 대조군보다 높은 경향을 나타내었다. 산양삼 추출물이 MC3T3-E1 조골세포에서 골 형성 관련 유전자 발현에 미치는 영향을 확인하기 위해 Runx2, ALP, OPN, OCN등의 유전자를 정량 real-time PCR을 통해 분석하였으며 대조군과 비교하여 모든 산양삼 추출물 처리군에서 농도 의존적이고 유의적으로 골 형성 관련 유전자발현이 증가되었다. 따라서 산양삼추출물이 골 형성 관련 유전자인 Runx2, ALP, OPN, OCN 발현을 증가시켜MC3T3-E1 조골세포의 분화를 촉진하고, 골 석회화 형성 촉진에 기여하였을 것으로 사료된다. 그러나 산양삼 추출물이 골형성과 관련하여 어떠한 기전으로 유전자의 발현을 조절하였는지에 대한 유전자 및 단백질 수준의 추가적인 연구와 산양삼 추출물의 분화 촉진과 석회화 형성능이 산양삼의 사포닌계 진세노사이드 성분의 영향인지에 대한 후속 연구가 필요할 것으로 사료된다.

  • 인삼은 외적 유해인자에 대한 비특이적 생체 저항력을 증진시켜주며 물리적, 화학적, 생물학적인 외적 변화에 대해 adaptogen으로서 작용한다. 인삼은 말초혈액 림파구에 의한 면역 인터페론 합성을 촉진시키며, 바이러스에 감염된 흰쥐에 대해 치료효과가 뚜렷하다. 인삼을 Semliki forest virus(SFV) 감염전후 계속 경구투여하면 $34{\~}40\%$의 보호 효과가 있었다. 인삼투여로 세포의 항체생성능이 증가되었으며, sheep의 적혈구 세포에 대한 혈행항체의 역가가 증진되었다. 또한 SFV 항원에 대한 면역성도 높아졌으며, N.K. 세포의 활성도도 크게 증가되었다. Aspergillus Ochraceus ATCC 28706 균주에서 추출한 6-MFA는 인터페론 유도물질 (inducer)로서 잘 알려져 있으며 두 종류의 인터페론, 즉 산성 용액에서 안정한 인터페론과 불안정한 인터페론을 유도시킨다. 인삼은 이들 두 종류의 인터페론 생성을 모두 증진시킨다. 동물실험 결과 6-MFA를 단독 처리하면 SFV 감염에 의해 낮은 보호작용을 보이나, 인삼투여를 병용하면 SFV 감염을 $100{\%}$ 완전히 방지할 수 있었다.

  • Recently, new ginseng cultivars having superior agricultural traits have been developed in Korea. For newly developed plant cultivars, the identification of distinctiveness is very important factors not only in plant cultivar management but also in breeding programs. Thus, eighty-five inter simple sequence repeat (ISSR) primers were applied to detect polymorphisms among six major Korean ginseng cultivars and two foreign ginsengs. A total of 197 polymorphic bands with an average 5.8 polymorphic bands and 2.9 banding patterns per assay unit across six Korean ginseng cultivars and foreign ginsengs from 236 amplified ISSR loci with an average 6.9 loci per assay unit were generated by 34 out of 85 ISSR primers. Three species of Panax ginseng including the Korean ginseng cultivars, P. quinquefolius, and P. notoginseng, could be readily discriminated using most tested primers. UBC-821, UBC-868, and UBC-878 generated polymorphic bands among the six Korean ginseng cultivars, and could distinguish them from foreign ginsengs. Sequence characterized amplified region (SCAR) marker system was introduced in order to increase the reproducibility of the polymorphism. One SCAR marker, PgI821C650, was successfully converted from the randomly amplified polymorphism by UBC-821. It showed the expected dominant polymorphism among ginseng samples. In addition, the specific polymorphism for Sunwon was generated by treating Taq I restriction enzyme to polymerase chain reaction products of PgI821C650. These results will serve as useful DNA markers for identification of Korean ginseng, especially Sunwon cultivar, seed management, and molecular breeding program supplemented with marker-assisted selection.
