Objectives: The aim of this experiment is to provide an objective differentiation of cultivated ginseng, mountain ginseng through component analysis, and to know the change of gin senoside components in the process of heating and fermentation Methods: Comparative analyses of ginsenoside $Rb_1$, $Rb_2$, Rc, Rd, Re, Rf, $Rg_1$, $Rg_3$, $Rh_1$, and $Rh_2$, from the cultivated ginseng 4 and 6 years, and mountain cultivated ginseng were conducted using HPLC (High Performance Liquid Chromatography, hereafter HPLC). And the same analyses were conducted in the process of heating and fermentation using mixed Lactobacillus rhamnosus, Lactobacillus plantarum, Bifidobacterium lactis for 7 days. Results: The change of ginsenosides to the process of red ginseng and fermentation, cultivated ginseng and mountain cultivated ginseng were showed another results. Mountain ginseng showed a lot of change compared with cultivated ginsengs. In the 7 days of fermentation, mountain ginseng showed that ginsenoside $Rg_1$, $Rb_1$, $Rb_2$, Rc, and Rd were decreased and increased ginsenoside Re, Rf, $Rg_3$ and $Rh_1$ were increased compared with cultivated ginseng Conclusions: It seemed that ginsenosides of mountain cultivated ginseng was better resolved than cultivated ginseng because the difference of structure or distribution of ginsenosides in the condition of fermentation.

Background: This article aims to compare and analyze the contents of ginsenosides in ginseng of different plant ages from different localities in China. Methods: In this study, 77 fresh ginseng samples aged 2-4 years were collected from 13 different cultivation regions in China. The content of eight ginsenosides (Rg₃, Rc, Rg₁, Rf, Rb₂, Rb₁, Re, and Rd) was determined using rapid resolution liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry (RRLC-Q-TOF MS/MS) to comparatively evaluate the influences of cultivation region and age. Results: Ginsenoside contents differed significantly depending on age and cultivation region. The contents of ginsenosides Re, Rc, Rg₁, Rg₃, and Rf increased with cultivation age, whereas that of ginsenoside Rb₁ peaked in the third year of cultivation. Moreover, the highest ginsenoside content was obtained from Changbai (19.36 mg/g) whereas the lowest content was obtained from Jidong (12.05 mg/g). Ginseng from Jilin Province contained greater total ginsenosides and was richer in ginsenoside Re than ginseng of the same age group in Heilongjiang and Liaoning provinces, where Rb₁ and Rg₁ contents were relatively high. Conclusion: In this study, RRLC-Q-TOF MS/MS was used to analyze ginsenoside contents in 77 ginseng samples aged 2-4 years from different cultivation regions. These patterns of variation in ginsenoside content, which depend on harvesting location and age, could be useful for interested parties to choose ginseng products according to their needs.

Aerobic cells are normally protected from the damage of free radicals by antioxidative on , zymes such as superoxide dismutase (SOD), catalase, glutathione (GSH) peroxidase, GSH S- transferase and GSH reductase which scavenge free radicals as well as nonenzymatic antioxidants such as ceruloplasmin, albumin and nonprotein-SH including GSH. The effects of each component (ginsenoside $Rb_1$, $Rb_2$, Rc, Rd, Re, $Rb_1$, Rf, $Rh_1$ and $Rh_2$) of red ginseng on the antioxidative enzyme activities were investigated in the liver in order to screen antioxidative components of red ginseng. Ginsenoside $Rb_1$ and Rc showed a tendency to increase GSH peroxidase activity, while ginsenoside Rc significantly decreased Cu,Zn-SOD activity. Especially, ginsenoside $Rh_2$ significantly increased catalase activity. These results suggest that ginsenoside $Rh_2$ is an important active component among total saponins of red ginseng.

North American ginseng (Panax quinquefolius L.) was analysed for total ginsenosides and ten major ginsenosides (R$_{0}$ , Rb$_1$, Rb$_2$, Rc, Rd, Re, Rf, Rg$_1$, pseudoginsenoside F$_{11}$ and gypenoside XVII), and variations in ginsenoside content with age of plant (over a four-year-period) and geographic location (Ontario versus British Columbia) were investigated. In the roots the total ginsenoside content increased with age up to 58-100 mgㆍg$^{-1}$ dry weights in the fourth year, but in leaves it remained constant over time. Roots and leaves, moreover, had different proportions of individual ginsenosides. The most abundant ginsenosides were Rb$_1$ (56mgㆍg$^{-1}$ for Ontario; 37mgㆍg$^{-1}$ for British Columbia) and Re (21mgㆍg$^{-1}$ for Ontario; 15 mgㆍg$^{-1}$ for British Columbia) in roots, and Rd (28-38 mgㆍg$^{-1}$ ), Re (20-25 mgㆍg$^{-1}$ ), and Rb$_2$ (13-19 mgㆍg$^{-1}$ ) in leaves. Measurable quantities of Rf were found in leaves (0.4-1.8 mgㆍg$^{-1}$ ) but not in roots or stems. Our results show that ginsenoside profiles in general, and Rf in particular, could be used for chemical fingerprinting to distinguish the different parts of the ginseng plant, and that ginseng leaves could be valuable sources of the ginsenosides Rd, Re, and Rb$_2$.

We demonstrated in previous study that protopanaxadiol and protopanxatriol saponins show antinociceptive activity in acetic acid induced writhing test and in the second phase (11-40 min) of formalin test but not tail-flick test. To identify further which ginsenoside has antinociceptive activity among various ginseng saponins, we have investigated antinociceptive effects of several ginsenosides using writhing and formalin test. Ginsenoside Rc, Rd, Re, and Rf induced antinociception in writhing test. These four ginsenosides also induced antinociception in the second phase of formalin (11-40 min) test but these ginsenosides showed a slight antinociception in the first phase (010 min) of formalin test except ginsenoside Rf. The antinociceptive effects induced by the ginsenosides were dose dependent and were not blocked by an opioid receptor antagonist, naloxone. The order of antinociceptive potency was Rd > Rc > Re > Rf in the formalin test. However, these ginsenosides did not show any significant analgesic effects in a tail-flick test. These results suggest that ginsenosides such as Rc, Rd, Re, and Rf inhibit tonic pain rather than acute pain induced by noxious heat. These results also indicate that the antinociceptive activity. Induced by ginsenosides may be one of the actions for pharmacological effects of Panax ginseng.

This study was compared the quality of red ginseng and characteristic changes of physicochemical properties according to the storage period (non storage, two days, six days, eight days, ten days) and store temperature $20^{\circ}C, \;34^{\circ}C,\;-10^{\circ}C)$. The water content of the fresh ginseng has a tendency to decrease as storage time increases. When we store the fresh ginseng for 10 days, the ideal storage temperature is considered to be $34^{\circ}C$ degrees. The amount of total nitrogen has a tendency to increase more than that of no storage as storage period approaches to 10 days. In the storage temperature, the amount of total nitrogen has a tendency to increase in the order of 1) room temperature, 2) freezing storage, 3) cold storage more than no storage. Cold storage has larger contents of total phenolic compounds than room temperature and freezing storage according to storage temperature. When we analyze the changes of a relative density of eight elements, ginsenoside $Rb_1,Rb_2,Rc,Rd,Re,Rg_3,Rg_1\;and\;Rg_2$ in red ginseng's saponin Rf according to storage condition, the relative density of $Rb_1\;and\;Rg_1$ against Rf diminishes in each storage condition as storage time increases. And it is also thought that density change of ginsenoside appears because of the materials, and change tendency according to storage condition is not clear. From functional nature on the evaluation of the quality, taste and fragrance of red ginseng according to storage district, it is evaluated that it is most recommendable for red ginseng to be transported and stored in $3{\sim}4$ degrees to keep its best condition.

Ginsenosides in epidermis·cortex(EC) and xylem-pith(XP) of main body of Panax ginseng(var. atropurpureacaulo) root were investigated in relation to dark purple area on stem. Pattern of ginsenosides, ratio of protopanaxatriol(PT) to diol(PD) and total ginsenoside content were significantly different between EC ana XP, and not related with stem color. The increasing trend of total ginsenosides with decreasing in purple area on stem needs to be tested with greater sample size. The order of ginsenoside content was $Rb_1>Rg_1>Re>Rc>Rg_2>Rb_2>Rf>Rd$ for EC, $Rg_1>Rb_1>Rg_2>Re>Rb_2>Rc>Rf>Rd$ for XP. PT/PD was 1.08 for EC,1.95 for XP. Since total ginsenoside content was 3 times higher in EC than in XP and weight of two parts was almost same, the content of ginsenosides of main body mostly depends on those of EC.

For the information on micellization at each ginsenoside level aqueous solution of purified saponin of Panax ginseng root was dialyzed through dialysis tubing (MW 12,000) or eluted through Bio-Gel P-2 (MW 200-2,000) and analysed for ginsenosides by high performance liquid chromatography. Ginsenosides can be classified into three groups depending upon molecular aggregation pattern and spatial arrangement of hydrophilic parts in molecule. Group I that is large micelle former(aggregation number: above 10) and one side hydrophilic part (HP) includes $ginsenoside\;Rb_1$, $Rb_2$, Rc and Rd (diols). Group II thai is small micelle former (aggregation number:>10-1) and semi-two sales HP includes $Rg_2$, Rf (triol) and $Rg_3$ (diol). Group III that is no micelle former (aggregation number: 1) and two sides HP includes Re and $Rg_1$ (triol).

Panax ginseng seedlings were grown in vermiculite with nutrient solution different in nitrogen, phosphorus ana potassium level. Ginsenoside contents of root were investigated by high performance liquid chromatogram. Elimination or increase of one of N.P.K. increased or decreased total saponin content. Nitrogen was most effective (15.5% for-N to 8.9% for 3N) and potassium least. Similar trend was shown in each ginsenoside. According to coefficient of variation in one nutrient treatment or among all nutrient treatments ginsenoside Re was most insensitive to nutrient change and also other environmental factors and Rd most sensitive. Diol content (PD) was more variable than triol (PT) and variation of PT/PD was about half of them. Variation of ginsenoside content by nutrient change had no relation with the ginsenoside content. Similarity of ginsenoside pattern slightly decreased with the difference of saponin content by nutrient change. Root weight was significantly small only in tap water plot.
