The principal objective of this study was to evaluate the quality characteristics of black ginseng jelly prepared with different 5 levels(0, 0.5, 1.0, 1.5, and 2.0%) of black ginseng extract. We assessed the ginsenosides level of white and black ginseng for comparison between white and black ginseng. And we conducted the pH, sugar content, Hunter's color values, the mechanical characteristics and sensory evaluation of black ginseng jelly samples. The levels of ginsenoside $Rg_3,\;Rh_1$, and $Rh_2$ of black ginseng were higher than those of white ginseng. The more black ginseng extract was increased, the sugar contents of black ginseng jelly were significantly increased(p<0.05). We noted that the luminance and Hunter's b values of jelly samples were decreased according to black ginseng extract was increased, but in Hunter's a values 0.5% black ginseng jelly was the highest of the all. With regard to the mechanical properties of the black ginseng jelly samples, the score of hardness, gumminess and chewiness were significantly increased. In color, taste and overall quality, the score of jelly with 1.0% black ginseng extract was significantly increased than those of the all.

Black ginseng and white ginseng were extracted with 80% ethanol and evaluated for relative ginsenoside composition, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities, and antioxidant properties. As analyzed by HPLC, black ginseng contained a greater proportion of ginsenoside $Rg_3$ compared to white ginseng. White ginseng was characterized by undetectable ginsenoside $Rg_3$ but it contained more total ginsenosides than black ginseng. Black ginseng extract exhibited higher (p<0.05) free radical-scavenging activity, as well as higher antioxidant activities than white ginseng against 2,2-diphenyl-1-picryl-hydrazyl, superoxide dismutase, and xanthine oxidase, despite the fact that the total saponin content was higher in white ginseng than black ginseng. In addition, the black ginseng extract displayed greater AChE and BChE inhibitory activities. These results suggest that black ginseng has stronger effects on anti-oxidation and AChE and BChE inhibition than white ginseng.

The abolishment of the red ginseng monopoly act by the Korean government in 1996 resulted in a drastic change in the Korean ginseng industry, leading to a significant increase in the market size and consumption of ginseng products. Red ginseng is most popular type, with approximately 74% of harvested fresh ginseng being processed into various red ginseng products. Since 1997, there has been a substantial increase in the cultivation of ginseng for production of red ginseng, which, in turn, has contributed to the proliferation of ginseng processing companies. To investigate the products of ginseng manufacturing businesses, we select 200 companies primarily engaged in ginseng processing or specializing solely in ginseng. Our survey on the status of ginseng industry covered 8 different categories. 1) Root ginseng: There were 66 companies involved in manufacturing red ginseng root, accounting for 33.0% of all surveyed companies. This was followed by black ginseng root with 36 companies (18.0%) and red ginseng fine roots with 22 companies (11%). 2) Red ginseng products: A total of 144 companies were involved in manufacturing red ginseng pouches, making it the most common product category. This was closely followed by 142 companies producing pure(100%) red ginseng extract concentrate. 3) Fermented red ginseng products: Companies producing fermented red ginseng extract concentrate products were the most numerous, totaling 26. Following this, companies producing fermented red ginseng stick and pouch products were next in line. 4) Ginseng products: There were 15 companies involved in the production of ginseng products, with the majority focusing on ginseng tea. 5) Black ginseng products: Companies producing black ginseng extract concentrate were the most numerous, with 31 companies, followed by 26 companies producing black ginseng extract pouches. 6) Taegeuk ginseng products: Only 5 companies were involved in the production of taegeuk ginseng products. 7) Fermented black ginseng, and 8) Ginseng berry products: These categories are manufactured by less than 5 companies each. However, the variety in ginseng berry products suggests the potential for future growth. In the 2000s, a trend emerged with the development of new processed products aimed at enhancing the functional components of red ginseng, and these products have captured the attention of consumers. However, this study primarily focuses on black ginseng, fermented red ginseng/fermented black ginseng, and ginseng berry products as they have exerted a significant influence on the overall ginseng industry.

The objective of this study is to provide the basic information for developing a high-value ginseng product using ginseng saponin and prosapogenin. In order to achieve such aim, Ginsenoside compositions of black ginseng (BG) extracts with various solvent conditions were examined by HPLC. The total saponin and the prosapogenin content of 95$\%$ ethyl alcohol extract were higher than that of the either 50$\%$ ethyl alcohol extract or distilled water extract. As a result, the order of the total saponin and the prosapogenin content was 1) 95$\%$ ethyl alcohol,2) 50$\%$ ethyl alcohol,3) the first and second mixture of 95$\%$ ethyl alcohol, distilled water, and 4) distilled water extract. In the case of fine black ginseng (FBG), the first and second mixture extracts of 95$\%$ ethyl alcohol and distilled water were the highest. In addition, the ratio of the protopanaxadiol group and the protopanaxatriol group (PD/PT) showed that the ratio of BG ranged from 0.304 to 0.601, while the ratio of FBG ranged from 1.166 to 1.657.

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.

This study evaluated cholineresterase inhibitory activity of Korean white ginseng extract (WGE), red ginseng extract (RGE), and black ginseng extract (BGE) and the cholinergic effect on scopolamine (SCOP)-induced amnesic mice. WGE, RGE, and BGE inhibited acetylcholineserase (AChE), as well as butyrylcholineserase (BuChE) in a concentration-dependent manner. BGE presented strong inhibition of AChE with an $IC_{50}$ value of 1.72 mg/mL, followed by WGE (5.89 mg/mL), RGE (6.30 mg/mL), respectively. The inhibitory activity of the three ginseng extracts on BuChE showed similar values among the groups. To better understand the mechanisms of the possible effect of ginseng extract on the cholinergic function, this study assessed the expression of the cholinergic markers of choline acetyltransferase (ChAT) and AChE using western blot and RT-PCR analysis in the brains of amnesic mice. Treatment with ginseng extracts led to inhibition of AChE expression and, the activation of ChAT expression in the hippocampus and the cerebral cortex of amnesic mice as induced by SCOP. The results suggest that ginseng extracts including BGE, appear to modulate the metabolism of acetylchoine (ACh), which would greatly increase synaptic ACh levels and most potently revert SCOP-induced amnesia.

The purpose of this study is to prepare black ginseng and evaluate its antitumor activity. In order to achieve such aim, 5 year fresh ginsenges were steamed at 95'E for 3 hr in pottery apparatus and dried at $60^{\circ}C$ for 12-36 hr. This process was repeated again nine times in same condition. Among the ginseng saponins in black ginseng, the amount of Ginsenoside $Rg_3$ was examined by HPLC. 10.05 mE of Ginsenoside $Rg_3$ was obtained from 1 g of dried black ginseng prepared. The extract of black ginseng exhibited stronger cytotoxic activity against MCF-1, HT-1080 and Hepa 1C1C7 tumor cell lines in vitro than the extract of red ginseng. Also, the extract of black ginseng exhibited stronger antitumor activity(33%) in BDFl mice bearing Lewis lung carcinoma cells(LLC) than the extract of red ginseng(23%). From these results, it was concluded that Black ginseng had antitumor activity suggesting its application for the prevention and treatment of cancer.

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.
