  • To compare and analyze the improvement effects of white ginseng extract, red ginseng extract, and black ginseng extract on cognitive dysfunction and memory impairment caused by scopolamine in rats. In the cognitive behavioral test, the tendency of the SCOP+B group to overcome the escape time delay induced by scopolamine administration was observed, unlike the SCOP group. The frequency on plat form was significantly increased in the group treated with ginseng extracts compared to the SCOP group. As a result of measuring the duration time on goal quadrant, the time spent in the quadrant was significantly increased in the SCOP+B group compared to the SCOP group. In the hippocampus, the SCOP-treated group significantly decreased the activity of AChE compared to the normal group, but the ginseng extract-treated groups significantly increased it compared to the SCOP group. After sacrificing the rats after the behavioral test, the expression of PSD95 protein in the excised brain was significantly decreased in the SCOP group compared to normal, but it was observed that the SCOP+R and SCOP+B groups were significantly increased compared to the SCOP group. CREB1 protein expression was significantly increased in the SCOP+R group, and the expression of Cdk5 was significantly increased in the SCOP+B group. Ginseng extracts significantly restored the memory damaged by scopolamine suggesting that red ginseng increased the expression of CREB1 and PSD95 proteins, and black ginseng increased the protein expression of Cdk5 and PSD95 to induce memory recovery.

  • Ginseng (Panax ginseng Meyer) has been used as traditional herbal drug in Asian countries. Ginsenosides are major components having pharmacological and biological efficacy like anti-inflammatory, anti-diabetic and anti-tumor effects. To control the quality of the components in diverse ginseng products, we developed a new quantitative method using LC-MS/MS for 13 ginsenosides; Rb1, Rb2, Rc, Rd, Re, Rf, 20(S)-Rh1, 20(S)-Rh2, Rg1, 20(S)-Rg3, F1, F2, and compound K. This method was successfully validated for linearity, precision, and accuracy. This quantification method applied in four representative ginseng products; fresh ginseng powder, white ginseng powder, red ginseng extract powder, and red ginseng extract. Here the amounts of the 13 ginsenosides in the various type of ginseng samples could be analyzed simultaneously and expected to be suitable for quality control of ginseng products.

  • The purpose of this study was to develop a new preparation process for chemical transformation of ginseng saponin glycosides to prosapogenins. Ginseng and ginseng extracts were processed under several treatment conditions using ascorbic acid solution. Treating with ascorbic acid at pH 2-3 and above $80^{\circ}C$ increased the ginsenoside $Rg_3$ content of samples to over 3% as compared to other pH levels and temperatures. In addition, ginseng and ginseng extracts that were processed under a high ascorbic acid solution treatment condition (pH 2.0, 5 hr) contained more ginsenoside $Rg_3$ (approximately 16 times) than those processed under a low ascorbic acid solution treatment condition (pH 3.0, 5 hr). The highest quantity of ginsenoside $Rg_3$ (3.434%) occurred when a sample of fine ginseng root extract (AG2-9) was processed with the ascorbic acid solution at pH 2.0 for 9 hr. However, there was no change in the amount of ginsenoside $Rg_3$ when fine ginseng root extracts were processed with ascorbic acid solution at pH 2.0 for over 9 hr. In conclusion, the results indicated that ascorbic acid treatment of ginseng extracts can produce a level of ginsenoside $Rg_3$ that is over 90-fold the amount found in commercial red ginseng.

  • 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.

  • 인삼의 메탄을 추출물을 몇 가지 유기용매를 사용하여 여러 분획으로 나누어서 이 분획들이 아미노아실-tRNA 합성효소의 활동성에 미치는 영향을 조사하였다. 백삼과 홍삼에 모두 아미노아실-합성효소의 활동성에 양성적인 효과를 나타내는 분획을 얻었다. 백삼의 경우에는 전체 메탄을 추출물에 그 성분이 있으며, 홍삼의 경우에는 메탄 올 추출물을 에테르로 추출한 분획에 그 성분이 있었다. 그러므로 이 효소에 양성적인 효과를 미치는 성분은 다소 무극성인 물질일 것으로 추측된다.

  • Background: Ginseng berries (GBs) show temporal metabolic variations among different maturation stages, determining their organoleptic and functional properties. Methods: We analyzed metabolic variations concomitant to five different maturation stages of GBs including immature green (IG), mature green (MG), partially red (PR), fully red (FR), and overmature red (OR) using mass spectrometry (MS)-based metabolomic profiling and multivariate analyses. Results: The partial least squares discriminant analysis score plot based on gas chromatography-MS datasets highlighted metabolic disparity between preharvest (IG and MG) and harvest/postharvest (PR, FR, and OR) GB extracts along PLS1 (34.9%) with MG distinctly segregated across PLS2 (18.2%). Forty-three significantly discriminant primary metabolites were identified encompassing five developmental stages (variable importance in projection > 1.0, p < 0.05). Among them, most amino acids, organic acids, 5-C sugars, ethanolamines, purines, and palmitic acid were detected in preharvest GB extracts, whereas 6-C sugars, phenolic acid, and oleamide levels were distinctly higher during later maturation stages. Similarly, the partial least squares discriminant analysis based on liquid chromatography-MS datasets displayed preharvest and harvest/postharvest stages clustered across PLS1 (11.1 %); however, MG and PR were separated from IG, FR, and OR along PLS2 (5.6 %). Overall, 24 secondary metabolites were observed significantly discriminant (variable importance in projection > 1.0, p < 0.05), with most displaying higher relative abundance during preharvest stages excluding ginsenosides Rg1 and Re. Furthermore, we observed strong positive correlations between total flavonoid and phenolic metabolite contents in GB extracts and antioxidant activity. Conclusion: Comprehending the dynamic metabolic variations associated with GB maturation stages rationalize their optimal harvest time per se the related agroeconomic traits.

  • 본 연구에서는 aeration 공정을 거친 홍삼 추출액의 유효성분 함량을 확인하고 항산화 활성에 미치는 영향을 알아보고자 하였다. Aeration 처리 유무에 따른 추출액의 색상 변화에서는 aeration 공정처리를 하지 않은 추출액과 aeration 공정처리 한 추출액 모두 추출시간이 경과함에 따라서 L값과 b값이 유의적으로 감소하였고, aeration 공정 처리 36시간 추출액에서 명도와 황색도가 가장 낮은 결과를 얻었다. a값은 non-aeration 처리에서는 추출시간이 경과함에 따라서 증가하였으나 aeration 처리할 경우에는 적색도가 감소되는 것을 확인할 수 있었다. 이와 같은 결과는 aeration 공정 처리를 할 경우에는 추출시간이 경과함에 따라 명도, 황색도, 적색도 모두가 감소되면서 갈색도가 증가하는 것을 의미하는 결과라고 할 수 있다. 총 폴리페놀 함량에서 non-aeration 홍삼추출액은 추출시간에 따라 0.62, 0.67, 0.72, 0.79 mg GAE/mL로 나타났으며 aeration 공정을 거친 추출액은 0.62, 0.70, 0.84, 0.96 mg GAE/mL로 추출시간에 따라 유의적으로 크게 증가하는 것을 확인하였다. 또한, 총 플라보노이드 함량은 aeration 공정을 거친 24, 36시간 추출액에서 21.77, 21.93 mg GAE/mL의 최고의 함량을 나타내었다. DPPH 라디칼 소거활성은 non-aeration 홍삼 추출액은 80.50-82.00% 범위에서 확인되었으며 aeration 공정을 거친 홍삼 추출액의 라디칼 소거능은 추출 시간에 따라 82.10, 81.90, 87.30, 87.10%로 나타났다. 이는 DPPH 라디칼 소거활성이 aeration 공정을 거침에 따라 활성이 증가한다는 것을 시사하는 결과이다. ABTS 라디칼 소거능은 24, 36시간에서 non-aeration 추출액이 96.80, 77.60%로 라디칼 소거활성이 떨어졌으나 aeration 공정을 거친 홍삼 추출액은 70.86, 98.60%로 추출 시간에 따라 유의적으로 소거활성이 증가하는 것으로 나타났다. 또한 10, 12, 24, 36시간 동안 aeration 공정을 거친 홍삼 추출액은 65.40, 65.03, 65.61, 63.26%의 hydrogen peroxidase 소거율을 보였고, 또한 0.87, 0.99, 1.04, 0.99로 환원력이 유의적으로 증가하는 것을 확인하였다. 이러한 결과들은 DPPH, ABTS의 경향과 유사하게 aeration 공정을 거침으로서 non-aeration보다 항산화능이 우수하다는 것을 나타냈다. Aeration 공정을 처리한 홍삼추출액으로부터 얻어진 진세노사이드의 함량은 non-aeration과 비교 했을 때 Rg3에서 현저히 차이가 나며, 저분자 진세노사이드 Rg3의 함량이 aeration 공정을 처리한 홍삼추출액에서 166.55, 219.71, 526.67, 581.13 ㎍/mL로 non-aeration 보다 많은 양이 생성되는 것을 확인 할 수 있었다. 이러한 결과들은 aeration 공정을 거친 홍삼추출액이 전반적으로 우수한 항산화 활성을 나타내었으며 향후 특정유효성분을 강화시킬 수 있는 새로운 공정방법으로 활용될 수 있을 것이라 사료된다.

  • 본 연구에서는 수삼을 식품에 쓰이는 산화 방지제인 ascorbic acid와 citric acid로 처리하여 홍삼을 제조한 후 활성성분인 페놀화합물과 진세노사이드의 추출물내 함량 변화를 HPLC를 이용하여 살펴보았다. 분석결과 citric acid 처리 홍삼에서 esculetin과 quercetin 함량이 무처리 홍삼에 비하여 각각 3.5 배, 2.0 배 증가하였고 ginsenoside 함량 역시 citric acid 처리시의 Rg$_3$, Rd, Rh$_2$ 증가량이 ascobic acid 처리시에 비하여 높았다. 따라서 인삼추출물의 이들 특정활성성분 강화를 위하여는 citric acid 처리가 효과적인 것으로 판단된다.
