This study was performed to analyze aroma pattern of Panax species (Korean Panax ginseng C.A. Meyer, Chinese Panax ginseng C.A. Meyer, Panax quinquefolium L, and Panax notoginseng F.H. Chen) by the PHGC (potable handheld gas chromatograph). Ratios of several peak areas in chromatogram of derivative parrtern were as follows. If ratio of Korean Panax ginseng was 1, Panax notoginseng was $0.030{\sim}0.674$, Chinese Panax ginseng was $0.005{\sim}0.212$ and panax quinquefolium was $0.241{\sim}0.871$. Ratios of peak area at $Rt_{20.02}$ were that if Korean panax ginseng was 1, Chinese Panax ginseng was 0.212, Panax quinquefolium was 0.343 and Panax notoginseng was 0.065. Ratios also of peak area at $Rt_{21.70}\;and\;Rt_{24.90}$ showed clear difference among aroma patterns of Panax specie cultivars. Flavor component at $Rt_{26.15}$ was not detected in Panax quinquefolium and Panax notoginseng but in Korean Panax ginseng and Chinese Panax ginseng. Ratios of peak area at $Rt_{26.15}$ were that if Korean Panax ginseng was 1, Chinese Panax ginseng was 0.185. And so habitat of Panax species cultivars was discriminated. Cultivar and habitat of dried panax species was remarkably distinguised by the chromatogram of frequency pattern, derivative pattern and visual pattern using olfactory images known as Vapor $print^{TM}$.

Objectives : We have examined the relaxational response to the water extract of genus Panax in rat thoracic aorta and mesenteric artery. Methods : Segments of thoracic aorta and mesenteric artery obtained from rats immediately after delivery were mounted in organ baths superfused on a polygraph. Results : We found that the thoracic aorta segments responded to the water extract of genus Panax with a dose-dependent vasorelaxation. At $10^{-5}m$ 5-hydroxytrptamine (5-HT), the maximal contraction force were 94.9% of the maximum KCl-response. At $10^{-5}m$ 5-HT - induced contraction, The contractile response of thoracic aortic rings were inhibited by 54.7%, 36.3% and 31.3% after addition of the high concentration (100 mg/ml) of water extract of Panax ginseng, Panax japonicus and Panax quinquefolium. The contractile response of mesenteric arteries were inhibited by 88.3%, 87.7%, and 70.3% after addition of the high concentration (100 mg/ml) of water extract of Panax ginseng, Panax japonicus and Panax quinquefolium. Conclusions : In conclusion, water extract of genus Panax - induced relaxation in the isolated rat thoracic aorta and mesenteric artery were composed of endothelium - independent relaxation and dose - dependent relaxation.

One prominent characteristic of2,3,7,8-tetrachlorodibenzop-dioxin (TCDD) toxicity in rats is a reduction of body weight accompanied by an altered serum lipid profile such as hyperlipidemia. A single administration of TCDD (50 ug/kg) resulted in a decrease of body weight and increase of serum cholesterol in rats. TCDD-induced weight loss and serum cholesterol elevation was reduced in rats administered with water extract (100 mg/kg) or saponin fraction (40 mg/kg) of Panax ginseng C.A.Meyer. In contrast, the administration of Panax quinquefolium did not inhibit the TCDD-induced weight loss and serum cholesterol elevation. Histological examinations of liver and testis revealed the administration of saponin fraction of Panax ginseng attenuated the TCDD-induced hispathologicallesions whereas the administration of saponin fraction of Panax quinquefolium did not. High performance liquid chromatographic analysis demonstrated high percentiles of ginsenoside Rg and ginsenoside $Rh_1$ were evident in saponin fraction of Panax ginseng. Results indicate that the protective effects of Panax ginseng, not Panax quinquefolium, on the TCDD-induced toxicity might be resulted from different compositions of saponins in Panax ginseng.

This study was carried out to obtain the basic information for the development of new ginseng varieties. The two variants (violet-stem variant and yellow-berry variant) of Korean ginseng (Panax ginseng C.A. Meyer) and American ginseng (Panax quinquefolium L.) of one to four-year were used for this study. All of the characteristics, such as leaf length, leaf width, petiol length, number of leaves per plant, number of leaflets per plants, stem diameter, stem length, number of stems per plant, root length, primary root length, root diameter, root weight were determined and correlations among them were estimated. The results obtained were summarized as follows. 1. Leaf length, petiol length, number of leaves per plant, and number of leaflets per plant of Panax ginseng, violet-stem variant and yellow-berry variant, were larger than those of Panax quinquefolium at all of the plant ages, while leaf width was wider in Panax quinquefolium. 2. The length of stem of Panax quinquefolium was shorter than that of Panax ginseng, and the frequency of multi-stem plants at 4-year-old ginseng was larger in violet-stem variant than in Panax quinquefolium and yellow-berry variant. 3. In the characteristics of ginseng root, the primary root length of Panax ginseng, violet-stem variant and yellow-berry variant, were less than that of Panax quinquefolium, while root weight, root diameter, and umber of secondary root related to yield were larger in Panax ginseng. 4. The root weight per plant related to the yield had positive and highly significant correlations with stem diameter, leaf length, leaf length, leaf width, number of compound leaves and leaflets in Panax ginseng and Panax quinguefolium. 5. The root weight related to the wield of ginseng had been influenced to stem diameter, leaf length, and leaf width directly, and number of compound leaves and leaflets indirectly. 6. The number, total area and activity of stomate per mm2 of Panax quinquefolium were more, larger and stronger than those of Panax ginseng.

Background: Panax notoginseng is a highly valued medicinal herb used widely in China and many Asian countries. Its root and rhizome have long been used for the treatment of cardiovascular and hematological diseases. Imaging the spatial distributions and dynamics of metabolites in heterogeneous plant tissues is significant for characterizing the metabolic networks of Panax notoginseng, and this will also provide a highly informative approach to understand the complex molecular changes in the processing of Panax notoginseng. Methods: Here, a high-sensitive MALDI-MS imaging method was developed and adopted to visualize the spatial distributions and spatiotemporal changes of metabolites in different botanical parts of Panax notoginseng. Results: A wide spectrum of metabolites including notoginsenosides, ginsenosides, amino acids, dencichine, gluconic acid, and low-molecular-weight organic acids were imaged in Panax notoginseng rhizome and root tissues for the first time. Moreover, the spatiotemporal alterations of metabolites during the steaming of Panax notoginseng root were also characterized in this study. And, a series of metabolites such as dencichine, arginine and glutamine that changed with the steaming of Panax notoginseng were successfully screened out and imaged. Conclusion: These spatially-resolved metabolite data not only enhance our understanding of the Panax notoginseng metabolic networks, but also provide direct evidence that a serious of metabolic alterations occurred during the steaming of Panax notoginseng.

This study was carried out to ascertain the basic information on characteristics of Korean Ginseng(Panax ginseng) and American ginseng(Panax quinquefolius), F$_1$ hybrids. Interspecies hybrids between Panax ginseng and Panax quinquefolius were examined morphological characteristics, rusty root incidence, and contents of effective ingredients such as ginsenosides. The summarized results are as follows. In Panax ginseng, rusty root incidence tended to increase with age of ginseng, but there was no difference in the incidence among ginseng ages and cultivation years in Panax quinquefolius and F$_1$ hybrid. The interspecies hybrid of panax ginseng and Panax quinquefolius flowered later than the Panax ginseng, but earlier than the Panax quinquefolius. As for the characteristics of ginseng root, Panax quinquefolius seedling was better than cv. Panax ginseng, as the former had longer and heavier seedling root than the latter. Ginsenosides of the hybrid F$_1$ showed intermediate value in amounts of Rb$_1$, Rb$_2$, Rc and Rd which were detected as in Panax gineng and Panax quinquefolius. The amount of Re of the hybrid was higher, but that of Rg$_1$ and Rg$_2$ in main and branch roots was lower compared with its parents. Rf was 0.14% and 0.20% in main and branch roots of Panax ginseng, respectively; however, no Rf was detected in Panax quinquefolius and in the hybrid F$_1$. This suggests there may be remarkable difference in Rf content among the ginseng species.

This study was conducted to investigate the metallothionein (MT) induction by Panax ginseng C. A. Meyer in cadmium chloride intoxication. The results were as follows: Generally, detoxicatlon effects by Panax ginseng C. A. Meyer extract increased proportionally to the increase of cadmium concentrations. When a 8 mg/g dosage of cadmium was administered, formation of the cadmium and EDTA complex showed the highest antitoxic effect. Also, when a 4 mg/g dosage of cadmium was administered, Panax ginseng C. A. Meyer extract showed the highest antitoxic effect in metallothionein induction. According to the above results, Panax ginseng C. A. Meyer extract administered with cadmium increased metallothionein concentration and decreased the toxicity of cadmium in liver.
