Allergies are immediate hypersensitive responses to antigens and interleukin (IL)-4 is involved in the initiation and development of allergic responses. $Rb_1$ has been known to have a variety of biological activities including anti-inflammatory activity, but the effect of $Rb_1$ on allergic responses is not known yet. The present study was undertaken to examine whether $Rb_1$ has an inhibitory effect on allergic response in mouse model. In allergic mouse model, our results showed that topical application of $Rb_1$ on atopic dermatitis (AD)-like skin lesions improved skin condition and inhibited starching behaviors. In addition, $Rb_1$ application not only suppressed mRNA expression of IL-4 and IL-10, but also prevented the nuclear factor of activated T cells 1 transcription. Moreover, $Rb_1$ application suppressed IL-4's secretion. Taken together, these results suggest that $Rb_1$ has a potent inhibitory effect in AD-related T cell cytokine production and may be a candidate for therapeutic agent in allergy.

This study was conducted to compare the contents of ginsenoside according the water extract conditions of red ginseng. In method A, red ginseng extract was prepared at $75^{\circ}C$ for 18 hours by 1 time extraction, and method B, the preparation was done at $85^{\circ}C$ for 18 hours by 1 time extraction. In method C, the primary extract prepared at $75^{\circ}C$ for 9 hours was blended with the secondary extract prepared by re-extracting the red ginseng residue obtained after the primary extraction, at $85^{\circ}C$ for 9 hours. Method D was the same procedure as method C but the extraction temperature for the primary extraction was $85^{\circ}C$ and that for the secondary extraction was $95^{\circ}C$. The contents of total and $Rb_1$, $Rg_1$ and $Rg_3$ ginsenoside were highest in Method C. The content of prosapogenin (ginsenoside $Rg_2$, $Rg_3$, $Rb_1$ and $Rb_2$) was highest in Method B. There was no consistent tendency in Brix, pH, Hue value and absorbance among extraction methods.

Streptozotocin-유도 당뇨병 모델을 이용하여 흑삼의 혈당강하작용에 대한 효과를 연구하고 증포과정에 따른 ginsenoside의 조성 변화를 분석하였다. 증포별 ginsenoside의 정량분석 결과, 증포 횟수가 증가할수록 조사포닌의 총량과 대부분의 ginsenoside는 줄어든 반면 ginsenoside-$Rg_3$ 함량 및 PD/PT 비율은 증가하는 경향을 보였는데, 이러한 조성은 다른 인삼제품과는 차별성 있는 특징이다. 또한, streptozotocin-당뇨병 유발쥐를 이용한 모델실험에서 흑삼추출물의 투여는 고혈당 준위(300 mg/dL이상)를 정상 수준(102 mg/dL)으로 감소시켰으며, 혈당 수준의 감소는 glycolysis나 HMT shunt 및 지방산 합성에 관여하는 glucokinase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, acetyl CoA carboxylase 등의 효소의 활성증대에 기인하는 것으로 판단되었다. 이러한 결과는 흑삼추출물의 유의적인 혈당강하 효과를 입증하며 이에 따라 신약이나 식이보조제의 항당뇨물질로서의 이용가능성을 시사한다.

Background: This article aims to compare and analyze the contents of ginsenosides in ginseng of different plant ages from different localities in China. Methods: In this study, 77 fresh ginseng samples aged 2-4 years were collected from 13 different cultivation regions in China. The content of eight ginsenosides (Rg₃, Rc, Rg₁, Rf, Rb₂, Rb₁, Re, and Rd) was determined using rapid resolution liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry (RRLC-Q-TOF MS/MS) to comparatively evaluate the influences of cultivation region and age. Results: Ginsenoside contents differed significantly depending on age and cultivation region. The contents of ginsenosides Re, Rc, Rg₁, Rg₃, and Rf increased with cultivation age, whereas that of ginsenoside Rb₁ peaked in the third year of cultivation. Moreover, the highest ginsenoside content was obtained from Changbai (19.36 mg/g) whereas the lowest content was obtained from Jidong (12.05 mg/g). Ginseng from Jilin Province contained greater total ginsenosides and was richer in ginsenoside Re than ginseng of the same age group in Heilongjiang and Liaoning provinces, where Rb₁ and Rg₁ contents were relatively high. Conclusion: In this study, RRLC-Q-TOF MS/MS was used to analyze ginsenoside contents in 77 ginseng samples aged 2-4 years from different cultivation regions. These patterns of variation in ginsenoside content, which depend on harvesting location and age, could be useful for interested parties to choose ginseng products according to their needs.

The main aim of this study was to investigate stress related activities of ginsenosides and their action mechanism. Control group and ginsenoside supplemented groups were exposed to stress while no-stress group was not done. Animals of each group (n=$8\~10$) were orally administerd 100 mg red ginseng extract (R-G), or 10 mg ginsenosides/kg body weight once a day. Animals were given materials for 5 days without stress, and then were given supplements for 5 days with restraint and electroshock stress. Mice were given materials for 5 days for experiments on anti-fatigue effect. After loading final stress, stress-related behavioral changes of experimental animals were examined and plasma corticosterone levels were measured. R-G and ginsenoside $Rb_{1}$ supplementation partially blocked the stress effects on locomotion and elevated plus-maze test in rats and mice. They also partially blocked stress induced behavioral changes such as freezing, smelling, face-washing, rearing behavior in rats. R-G and $Rb_{1}$ decrease adrenal gland size and plasma corticosterone level, which were increased by stress in rats. R-G increased enduring time on the Rota rod, cold water and horizontal wire, but $Rb_{1}$ didn't. Effects of $Rb_{1}$ on plusmaze test were inhibited by administration of flumazenil. These results suggest that $Rb_{1}$ is the main antistress principle in ginseng and it's effect is modulated by GABAnergic nervous system.
