  • Background: Korean Red Ginseng has been used as a traditional oriental medicine to treat illness and to promote health for several thousand years in Eastern Asia. It is widely accepted that ginseng saponins, ginsenosides, are the major active ingredients responsible for Korean Red Ginseng's therapeutic activity against many kinds of illness. Although the crude saponin fraction (CSF) displayed antiplatelet activity, the molecular mechanism of its action remains to be elucidated. Methods: The platelet aggregation was induced by collagen, the ligand of integrin ${\alpha}_{II}{\beta}_I$ and glycoprotein VI. The crude saponin's effects on granule secretion [e.g., calcium ion mobilization and adenosine triphosphate (ATP) release] were determined. The activation of mitogen-activated protein kinases (MAPKs), including extracellular signal-regulated protein kinase 1/2 (ERK1/2), c-Jun N-terminal kinases (JNKs), and p38 MAPK, and phosphoinositide 3-kinase (PI3K)/Akt was analyzed by immunoblotting. In addition, the activation of integrin ${\alpha}_{II}b{\beta}_{III}$ was examined by fluorocytometry. Results: CSF strongly inhibited collagen-induced platelet aggregation and ATP release in a concentration-dependent manner. It also markedly suppressed $[Ca^{2+}]_i$ mobilization in collagen-stimulated platelets. Immunoblotting assay revealed that CSF significantly suppressed ERK1/2, p38, JNK, PI3K, Akt, and mitogen-activated protein kinase kinase 1/2 phosphorylation. In addition, our fraction strongly inhibited the fibrinogen binding to integrin ${\alpha}_{IIb}{\beta}_3$. Conclusion: Our present data suggest that CSF may have a strong antiplatelet property and it can be considered as a candidate with therapeutic potential for the treatment of cardiovascular disorders involving abnormal platelet function.

  • Background: Heat treatments are applied to ginseng products in order to improve physiological activities through the conversion of ginsenosides, which are key bioactive components. During heat treatment, organic acids can affect ginsenoside conversion. Therefore, the influence of organic acids during heat treatment should be considered. Methods: Raw ginseng, crude saponin, and ginsenoside $Rb_1$ standard with different organic acids were treated at $130^{\circ}C$, and the chemical components, including ginsenosides and organic acids, were analyzed. Results: The organic acid content in raw ginseng was 5.55%. Organic acids were not detected in crude saponin that was not subjected to heat treatment, whereas organic acids were found in crude saponin subjected to heat treatment. Major ginsenosides ($Rb_1$, Re, and $Rg_1$) in ginseng and crude saponin were converted to minor ginsenosides at $130^{\circ}C$; the ginsenoside $Rb_1$ standard was very stable in the absence of organic acids and was converted into minor ginsenosides in the presence of organic acids at high temperatures. Conclusion: The major factor affecting ginsenoside conversion was organic acids in ginseng. Therefore, the organic acid content as well as ginsenoside content and processing conditions should be considered important factors affecting the quality of ginseng products.

  • Antifungal activities of crude extractum of Nanshancha Seed Cake (NSC), to inactivate postharvest pathogens were investigated. Highest inhibitory rate was found against C. musae, C. gloeosporioides and C. papaya P.Henn, which was much stronger than that by tea saponin. Compared to tea saponin, effects of NSC extractum was relatively weak and similar on C. gloeosporioides Penzig and P. italicum. In an in vivo study, best controlling effects by NSC extractum was found with banana anthracnose disease development, which showed no inhibitory effects by tea saponin. NSC extractum controlled in vitro C. musae growth through directly inhibiting germination rate and germ tube elongation, and causing distortation, rupture and indentation of C. musae mycelium. In banana fruit subject to C. musae inoculation, higher PAL, POD, GLU and CHT activity was observed in banana fruit treated with crude NSC extractum than that of water control fruits. Current study proved the best controlling effects of crude NSC extractum in C. musae in vitro and in vivo development, which through direct inhibition of C. musae growth and increasing defense system of the banana fruit.

  • S. aureus, E. coli, C. albicans, A. niger 등 4종의 식중독균에 대해 agar diffusion법을 이용하여 홍삼(Panax ginseng C.A.Meyer)으로 부터 조제한 홍삼농축액, 조사포닌, 비수용성 분획에 대한 항균활성을 조사하였다. 그 결과, 홍삼농축액 및 비수용성분획은 E. coli, C. albicans, A. niger에 대해서는 항균활성을 나타내지 않았고 조사포닌도 고농도인 30%를 제외한 모든 농도에서 항균활성을 나타내지 않았다. S. aureus는 Gram positive 세균으로서 화농성 식중독의 원인균이면서 동시에 아토피성 피부염의 원인균으로 알려져 있는데, 홍삼농축액은 30% 농도에서 이 균에 대해 항균활성을 나타내었고 조사포닌도 7.5%에서 항균활성을 나타내었다. 홍삼으로부터 조제한 비수용성 분획도 10~200 mg/mL 농도로 실험한 결과 모든 분획에서 항균효과를 나타내었다. 조사포닌 및 홍삼농축액의 미생물 생육저해양상을 조사하기 위해 미리 S. aureus를 접종한 0.85% 생리식염수에 농축액 및 조사포닌을 농도별로 첨가하고 35℃, 12시간 배양한 후 생균수를 측정한 결과, 홍삼농축액은 10% 이상의 농도에서, 조사포닌은 2% 이상의 농도에서 각각 균의 생육을 억제하였다. 그러나 이러한 농도에서도 생균수는 완전히 사멸되지 않아서 홍삼농축액 및 조사포닌의 S. aureus에 대한 생육억제작용은 살균작용이 아닌 정균 작용으로 추정되었다. 사포닌의 항균활성 유무를 확인하기 위해 순수 분리된 ginsenoside 6종(PT saponin, PD saponin, ginsenoside-Rb2,-Rc,-Rd,-Rf,-Rg2)의 항균활성을 50~200 ㎍/mL의 농도에서 조사한 결과 모두 항균효과가 관찰되지 않아서 ginsenoside는 S. aureus에 대해서는 항균효과가 없는 것으로 사료된다. 한편 사포닌을 제외한 비사포닌 성분인 비수용성분획에 대해 상기의 4종 병원성미생물을 대상으로 항균활성을 조사한 결과 E. coli, C. albicans, A. niger에 대해서는 항균효과가 관찰되지 않았고 S. aureus에 대해서만 선택적인 항균활성을 나타내었다. 항균활성 발현 비수용성분획 중 15% methanol분획(MF-1)이 가장 높은 항균활성을 나타내어 이에 대한 최소생육저해농도를 조사한 결과 0.625 mg/mL 이었다. MF-1 분획을 질량분석기(HPLC-MS)로 조사한 결과 주요한 활성성분은 분자량 179.55 및 187.55를 가지는 물질로 추정되었다.

  • In this study, we isolated ginseng crude saponin (GCS) from Korean red ginseng (KRG) and determined the ginsenoside content in it to investigate the physiological and pathological effects of GCS on acute pulmonary inflammation induced by intratracheal instillation of cigarette smoke condensates (CSC) and lipopolysaccharide (LPS) solution in BALB/c mice. GCS was orally administered at doses of 10 mg/kg and 25 mg/kg for 3 weeks. The recovery rate of GCS from KRG was 6.5 % and total ginsenosides from GCS was 1.13 %, and the content of Rb1 was the highest among them. Total inflammatory cells in the lung homogenates and bronchoalveolar lavage fluid (BALF) increased following intratracheal administration of CSC and LPS. However, GCS administration impaired this increase. Furthermore, it inhibited the increase in leukocytes in the blood, considerably decreased neutrophils in BALF, and declined infiltration of inflammatory cells and deposition of collagen in the tracheal and alveolar tissue. In this study, GCS was found to have a protective effect against acute pulmonary inflammation and it may be beneficial in preventing various respiratory diseases.

  • The purpose of this study was to investigate the anti-obesity effects of crude saponin (CS) in Korean red ginseng (KRG) on rats fed a high fat (HF) diet. Methods: Male Sprague-Dawley (SD) rats were divided into a normal diet group and a high-fat (HF) diet group. The HF diet group became obese from being fed a HF diet over five weeks. The normal diet group were fed a normal diet. Each CS group of the normal diet group and HF diet group was administered CS (200 mg/kg, i.p.) for three weeks, the control group of both types was administered normal saline (1ml/kg, i.p.) instead of CS. Each group had 5 rats. Results: After administration of CS, the body weight, food consumption, adipose tissues, and expression of appetite peptides such as leptin and neuropeptide-Y (NPY) were investigated in the HF diet group as well as the normal diet group. Administration of CS reduced body weight, food intake, and fat content in the HF and normal diet groups. After CS administration, NPY expression and leptin were lower in the HF diet group. Conclusions: Our results suggest that CS may be useful in the treatment of obesity, especially of type qixu (氣虛).

  • To enhance the functionalities of ginseng, an acid impregnation pre-treatment was applied during red ginseng processing. Acetic, ascorbic, citric, malic, lactic, and oxalic acid were used for the acid impregnation treatment, and total and crude saponin concentrations and ginsenoside patterns were evaluated. Total and crude saponin contents of red ginseng pre-treated by acetic, ascorbic, and citric acid were similar to those of red ginseng without pre-treatment, whereas lactic, malic, and oxalic acid pre-treatment caused a reduction of total and crude saponin in red ginseng. From the high performance liquid chromatography analysis of ginsenosides, increased $Rg_3$ density was shown in red ginseng pre-treated by acetic, ascorbic, and citric acid impregnation. In the case of lactic, malic, and oxalic acid pre-treatment, increased $Rg_1$ density was observed in red ginseng. Increased $Rg_1$ and $Rg_3$ contents due to acid impregnation during red ginseng processing may contribute to improving bioactive functionalities of red ginseng.
