This study was carried out to investigate spectral irradiance characteristics of blue, yellow, and blue-black colored polyethylene (PE) shading net and the effect on growth characteristics and yield in ginseng seedling. The spectral irradiance $({\mu}mol/m^2/s/nm)$ showed the peak at 498 nm in both of blue and blue-black PE shading net, and 606 nm under yellow PE one. The intensity of blue light in blue shading was more strong than that of blue-black shading, control. Blue shading was increased by 17% and 23% in accumulated quantum for daytime, $0.5^{\circ}C and $0.2^{\circ}C$ in maximum temperature on June 2 than that of yellow and blue-black shading, respectively, but heat injury ratio of the former was lower than that of the latter. Chlorophyll content and stem length in blue shading were decreased more significantly than those of yellow and blue-black shading. The specific leaf weight was higher under blue and yellow shading than that of blue-black shading. Ginseng seedling harvested in blue shading was increased by $13{\sim}17%$ in the number of root, and $17{\sim}20%$ in root weight per $m^ 2 compared to yellow and blue-black shading owing to the increase of survived plant, and the decrease of specific leaf weight, heat injury ratio, and stem length.

두뇌기능을 활성화시킬 수 있는 새로운 기능성 김치를 개발하기 위하여 다양한 농도의 흑삼추출물을 첨가한 배추김치를 제조한 후 $4^{\circ}C$에 30일간 저장하면서 경시적으로 김치의 물리화학적 생물학적 관능적 품질을 측정하였다. 0.5~5% 흑삼추출물을 첨가한 김치의 색도를 측정한 결과, 대조구보다 L 값은 감소하고 a 값과 b 값은 증가하여 김치의 색은 암갈색~흑색을 나타내었다. 1~5%의 흑삼추출물을 첨가한 김치는 대조구보다 pH 감소 및 산도 증가가 늦게 나타났고, 경도의 감소 경향도 낮았으며 젖산균 및 효모 증가도 더디게 나타났다. Acetylcholinesterase 활성 저해정도를 측정하였을 때, 흑삼처리구는 대조구보다 약 2배 정도 높은 저해도를 나타내었으며 흑삼의 첨가 농도가 높을수록 저해 정도가 높았다. 김치의 최적 숙성 적기를 전후하여 관능검사를 실시한 결과, 1~3% 흑삼처리구는 흑삼농도가 높을수록 관능특성이 높았으나, 5% 흑삼처리구는 김치에서 흑삼의 맛과 향이 강하여 관능특성이 대조구보다 낮았다. 김치를 제조할 때에 흑삼추출물을 첨가하면 처리농도에 비례하여 김치의 가식기간이 약 15일 정도 연장되었다. 따라서 두뇌기능활성화 효과가 있는 김치를 제조할 때에는 3%의 흑삼추출물을 첨가하는 것이 가장 효율적인 것으로 사료되었다.

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.

Black ginseng is produced by a repeated steaming process. The aim of this study was to investigate the anti-obesity effects of black ginseng ethanol extract (BG-EE) in high fat (HF) diet-fed mice. Two groups were fed either a normal control (NC) diet or a HF diet (45% kcal fat). The other three groups were given a HF diet supplemented with 1% BG-EE, 3% BG-EE, and 5% BG-EE for 12 wk. The anti-obesity effects of the BG-EE supplement on body weight, the development of fat mass, and lipid mechanisms were assessed in obese mice. HF-induced hyperlipidemia, fat accumulation in the liver, and white adipose tissues were reduced after BG-EE supplementation. Total fecal weight and the amount of fecal fat excretion also were increased after BG-EE supplementation. These results suggest that BG-EE may be useful to ameliorate HF-induced obesity through the strong inhibition of fat digestion.

A high performance liquid chromatography (HPLC) method has been developed for determination of 11 ginsenosides in black ginseng (BG, white ginseng that is subjected to 9 cycles of $95^{\circ}C$ for 3 hr). After eluted by gradient elution of water-acetonitrile without buffer in 70 min, 11 ginsenosides in BG were identified. The proposed method provided good linearity ($R^2$>0.9995), accuracy (92.2-106.6%), and intra- and interday precision (RSD<2.6%). In addition, ginsenosides compositions in white, red, and black ginsengs were investigated using this method, respectively. Interestingly, in BG, the content of ginsenoside $Rg_3$ which does not existed in white ginseng was 7.51 mg/g, approximately 20 times than that in red ginseng.

This study compared the contents of ginsenosides depending on steaming conditions of red ginsengs to provide basic information for developing functional foods using red ginsengs. The red ginseng steamed eight times at $98^{\circ}C$ ranked atop the amounts of prosapogenins ever detected in red ginsengs (ginsenoside $Rg_2$, $Rg_3$, $Rg_5$, $Rg_6$, $Rh_1$, $Rh_4$, $Rk_1$, $Rk_3$, $F_1$, $F_4$, 1.15%) among red ginsengs steamed more than twice. When steamed eight times at $98^{\circ}C$, 2.7 times as much prosapogenins such as ginsenosides $Rg_2$, $Rg_3$, $Rg_5$, $Rg_6$, $Rh_1$, $Rh_4$, $Rk_1$, $Rk_3$, $F_1$, and $F_4$ as those steamed just once at $98^{\circ}C$ was collected. In addition, the red ginsengs steamed eight times at $98^{\circ}C$ contained more amounting ginsenoside $Rg_3$ (0.28%) than that in the red ginseng steamed several times at random. Accordingly, it is recommendable that red ginsengs steamed 8 times, which proved to be the optimal steaming condition, be used rather than those steamed 9 times (black ginsengs), in order to develop red ginseng products of high prosapogenin concentration and high functions.

This study compared the contents of ginseng prosapogenin depending on the extracting conditions of Ginseng Radix palva(Panax ginseng) to provide basic information for developing Ginseng Radix palva-based functional foods. Our findings show that the content of crude saponin peaked at 18 hours of extraction and when extracted twice at $100^{\circ}C$ (GRP-18). However, the content of total saponin reached its height at 6 hours of extraction at $100^{\circ}C$ (GRP-6) and when extracted twice. On the other hand, the content of ginsenoside $Rg_3$, $Rg_5$ and $Rk_1$ from Red and Black ginseng reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction at $100^{\circ}C$. And at $100^{\circ}C$ the main prosapogenin of the content of Black ginseng ginsenoside $Rg_5$ and $Rk_1$ reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction.

The purpose of this study is to develop a new preparation process of Notoginseng root(Panax notoginseng) extracts having high concentrations of ginsenoside $Rg_3$, $Rg_5$, $Rk_1$ and $Rh_4$, a special component of Red and Black ginseng(Panax ginseng). Chemical transformation from ginseng saponin to prosapogenin was analyzed by the HPLC. Extracts of Notoginseng root was processed under several treatment conditions including microwave and vinegar(about 14% acidity) treatments. Results of those treatments showed that the quantity of ginsenoside $Rg_3$ increased by over 7.6% at 15 minutes of pH 2~4 vinegar and microwave treatments. The results of processing with MPN-15 indicate that the microwave and vinegar(about 14% acidity) processed Notoginseng root extracts that had gone through 15-minute treatments were found to contain the largest amount of ginsenoside $Rg_3$(7.639%), $Rg_5$(6.061%), $Rk_1$(1.516%) and $Rh_4$(1.599). It is thought that such results provide basic information in preparing Notoginseng root extracts with functionality enhanced.

Objectives : This study was performed to efficiently make Black Panax Ginseng (BPG) and evaluate its antitumor activity. Methods : Panax ginseng was steamed at $95^{\circ}C$ for 3 h, dried and steamed again at $115^{\circ}C$ for 6 h. The main ginsenosides of BPG were $Rg_{3}$, $Rk_{1}$ and $Rg_{5}$. Results : Among the saponins in BPG, the amount of ginsenoside $Rg_{3}$ was determined by HPLC method. The 11.48 mg of ginsenoside $Rg_{3}$ was obtained from lg of dried BPG. The crude saponin fraction (CSF) of BPG was tested in vitro for its cytotoxic activities against various human cancer cell lines, such as ACHN, NCI-H23, HCT-15 and PC-3. The CSF of BPG exhibited stronger cytotoxic activity than that of red Panax ginsneng. CSF of BPG exhibited good cytotoxic activities against ACFIN, HCT-15, and PC-3 cell lines with $IC_{50}$ values of 60.3-90.8 ${\mu}g$/ml. However, CSF of BPG did not show any cytotoxic activity against NCI-H23 cell line. Conclusions : BPG produced by new manufacturing is more effective than BPG produced by existing processing in anticancer activity. And new BPG has a possibility of investigation because of high contents of Rg3, Rk1 and Rg5 that have various phisological activities.
