We have conducted a comprehensive literature review regarding the chemical constituents and biological activities of Korean black ginseng(Panax ginseng C. A. Meyer), three to nine times-steamed and dried ginseng, which shows strong black color through Maillared browning reaction. It has been reported that some chemically deglycosylated and transformed saponins are obtained from black ginseng as artifacts produced during intensive steaming. They have been known to be ginsenosides Rg3, Rg4, Rg5, Rg6, Rh1, Rh2, Rh4, Rk1 and Rk3, quite different from those of red ginseng, among which ginsenosides Rg3, Rg5 and Rk1 are considered to be major components. And also, black ginseng has been recently found to demonstrate anticancer, recovery from learning and memory damages, hypontensive, antidiabetic, antiobesitic, tonic and antiatopic activities, together with antioxidative and exercise performance improving activities, exhibiting their effects to be a little bit stronger than those of red ginseng. These findings suggest that black ginsng might play an important role in the development of promising functional foods and drugs from the viewpoint of the chemical composition and biological activities of black ginseng with a distinction from those of white and red ginsengs. In this review, the authors will survey and evaluate further functions of black ginseng with a focus on its physicochemical properties and biological activities.

Korean ginseng(Panax Ginseng C.A. Meyer) known as a oriental miracle drug is an important medicinal plant. Ginseng has been used for geriatric, tonic, stomachic, and aphrodisiac treatments for thousands years. Also, it is an antibiotic and has therapeutic properties against stress and cancer. Ginseng is widely distributed all over the world. Among them, Korean mountain ginseng has the most valuable effect on pharmaceuticals. The roots of mountain ginseng contained several kinds of ginsenosides that have many active functions for the human body. However, the study of mountain ginseng has a limit because the mountain ginseng is very expensive and rare. So, we artificially cultured mountain ginseng adventitious roots using the bioreactor culture system. We induced callus from original mountain ginseng, directly dug up in mountain and aged about one hundred ten years. Separated adventitious roots were precultured in 500ml conical flasks and then, transferred in 20L bioreactors. The adventitious roots of mountain ginseng were harvested after culturing for 40days, dried and then, extracted with several solvents. In this study, we investigated the whitening effect, anti-wrinkle effect and the safety of tissue cultured adventitious roots extract of mountain ginseng in order to identify the merit as a cosmetic ingredient. Particularly, extract of mountain ginseng adventitious roots showed whitening and anti-wrinkle effects. The inhibitory effect of this extract on the melanogenesis was examined using B-16 melanoma cell. When B-16 melanoma cells were cultured with adventitious root extract, there was a dramatically decrease in melanin contents of 8-16 melanoma cell. And we identified this extract inhibited Dopa auto-oxidation significantly. Also, when transformed mouse fibroblast L929 cells were treated with this extract, there was a significant increase in collagen synthesis. The results show significant inhibited melanization and wrinkle without inhibiting cell viability.

The objective of this study was to investigate antioxidant activities of freeze-dried, main root, and fine root of ginseng (Panax ginseng CA. Meyer), which were extracted with various solvents including ethanol, methanol, and water. Ethanol extracts in both parts showed the most powerful scavenging activities against DPPH radicals. Especially, ethanol extract of fine root had higher reducing power and antioxidant capacity than that of main root. The highest antioxidant activity in linoleic acid emulsion system was also observed in fine root extracted with ethanol, followed by methanol and water. Both ferrous ion chelating activity and ferric reducing antioxidant power (FRAP) of extracts were increased with the increase of extracts concentration. These results suggest that ethanol extract of fine root of ginseng has the most effective antioxidant capacity compared to the methanol and water extracts tested in the present study. Thus it can be applied for the effective extraction of functional material from ginseng for the usage of pharmaceutical and/or food industries.

This study was conducted to develop a optimal composite recipe of a functional cookie including Red Ginseng powder and having the high preference to all age groups. Wheat flour was partially substituted by Red Ginseng powder to reduce the content of wheat flour. The sensory optimal composite recipe was produced by making iced cookies, with 5 levels of Red Ginseng $powder(X_1),\;sugar(X_2),\;butter(X_3)$, respectively, by C.C.D(Central Composite Design) and by conducting the sensory evaluation and the instrumental analysis by Response Surface Methodology(RSM). The results of sensory evaluation showed very significant values in color, appearance, texture, overall quality(p<0.05), flavor(p<0.01) and those of instrumental analysis showed significant values in lightness, redness(p<0.05), spread ratio, hardness(p<0.01). As a result, sensory optimal ratio of Red Ginseng cookie was calculated at Red Ginseng powder 25.4 g, sugar 147.1 g, butter 153.4 g.

This stuffy was carried to establish a new efficient method for the preparation of edible crude ginseng saponin. The conventional butanol extraction and resin adsorption methods were compared for the contents of total crude ginseng saponin and major ginsenosides. Seventy- percent methanol extract was applied to Diaion HP-20 column and the resin was washed with Hn and eluted with absolute methanol. The methanol elute was dried in vivo and analyzed for its ginsenosides. Use of ethanol instead of methanol to make edible crude ginseng saponin gave a similar result. Butanol extraction was performed by the conventional method. The final aqueous layer from butanol extraction was passed through Diaion HP-20 column followed by elution with methanol and Diaion HP-20 passed fraction was extracted with butanol to recover remaining components, respectively, in order to determine saponin loss. TLC and HPLC qualitatively and quantitatively monitored Ginsenosides, respectively. Loss of ginsenosides was higher in butanol extraction method than in Diction HP-20 adsorption method. In addition, saponin fractions prepared by Diction HP-20 adsorption method showed higher content of each ginsenoside, showing 8.2% higher purity than that of butanol extracted fraction. From these results, we propose the resin adsorption method as a new efficient measure for the preparation of crude ginseng saponin, which is edible by using spirit instead of methanol.

Fresh (raw roots), white (dried), and red (steamed-drid) ginseng samples were gamma-irradiated at 0 to 7 kGy. Electron spin resonance (ESR) technique was used to characterize the irradiation status of the samples, targeting the radiation-induced cellulose radicals after different sample pretreatments. All non-irradiated samples exhibited a single central signal (g=2.006), whose intensity showed significant increase upon irradiation. The ESR spectra from the radiation-induced cellulose radicals, with two side peaks (g=2.0201 and g=1.9851) equally spaced (${\pm}3mT$) from the central signal, were also observed in the irradiated samples. The core sample analyzed after alcoholic-extraction produced the best results for irradiated fresh ginseng samples. In the case of irradiated white and red ginseng samples, the central (natural) and radiation-induced (two-side peaks corresponding to cellulose radical) signal intensities showed little improvement on alcoholic-extraction. The water-washing step minimized the effect of $Mn^{2+}$, but reduced the intensity of side peaks making them difficult to indentify. The effect of different origins was negligible, however harvesting year showed a clear effect on radiation-induced ESR signals.

Background: The structural conversions in ginsenosides induced by steaming or heating or acidic condition could improve red ginseng bioactivities significantly. In this paper, the chemical transformations of red American ginseng from fresh Panax quinquefolium L. under steaming were investigated, and the possible mechanisms were discussed. Methods: A method with reversed-phase high-performance liquid chromatography coupled with linear ion trap mass spectrometry ($HPLC-MS^n$)-equipped electrospray ionization ion source was developed for structural analysis and quantitation of ginsenosides in dried and red American ginseng. Results: In total, 59 ginsenosides of protopanaxadiol, protopanaxatriol, oleanane, and ocotillol types were identified in American ginseng before and after steaming process by matching the molecular weight and/or comparing $MS^n$ fragmentation with that of standards and/or known published compounds, and some of them were determined to be disappeared or newly generated under different steaming time and temperature. The specific fragments of each aglycone-type ginsenosides were determined as well as aglycone hydrated and dehydrated ones. The mechanisms were deduced as hydrolysis, hydration, dehydration, and isomerization of neutral and acidic ginsenosides. Furthermore, the relative peak areas of detected compounds were calculated based on peak areas ratio. Conclusion: The multicomponent assessment of American ginseng was conducted by $HPLC-MS^n$. The result is expected to provide possibility for holistic evaluation of the processing procedures of red American ginseng and a scientific basis for the usage of American ginseng in prescription.
