This study was carried out to obtain the basic information on the development of flower bud and to clarify the characteristics of flower organ and flowering in Korean ginseng (Panax ginseng) and American ginseng (Panax quinquefolium). The formation of flower bud in the dormancy bud of Korean ginseng was initiated about the middle of June and completed late in September. The ovary, style and anther of Panax ginseng, violet-stem and yellow-berry variants, were formed earlier than those of Panax quinquefolium. Panax ginseng, therefore, flowered earlier by one month in comparison with Panax quinquefolium. As for the effect of temperature on the flowering of ginseng, both species, Panax ginseng and Panax quinquefolium, grown at 20 $^{\circ}C$ flowered earlier than those at 15 $^{\circ}C$ and field conditions, but did not flower at 30 $^{\circ}C$. Seed characters were better in Panax ginseng than in Panax quinquefolium and the amount of seeds showed the highly significant positive correlation coefficient with peduncle length in both Panax ginseng and Panax quinquefolium.

The amounts of ginseng acidic polysaccharide (GAP) in red ginseng (Panax ginseng) were higher than those of wild and cultured Panax quinquefolius, Panax notoginseng as well as white ginseng (Panax ginseng). In white ginseng, there is no difference in the GAP amount among root ages or sizes. Also, the GAP amount of red ginseng body was similar to that of ginseng rhizome, but was higher than that of leaf and epidermis.

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.

This study was carried out to compare the root yields, root characters, saponin and ginsenosides contents of 6-year-old p. ginseng and p. quinquefolium. These two ginseng species showed difference in the diameter and ten비h of mainroot. The main root length or p. quinquefolium was shorter than that of p. ginseng, whereas Jakyung-jong and Hwangsook-jong of P. ginseng showed similar root length. Proximate composition were similar between the two species, however, crude fibercontent was significantly higher in main and lateral root of Jakyung-jong and Hwang sook-jong of P ginseng than P quinquefolium. In regard to mineral contents of root, P ginseng contained more Ca and Mn and less Fe and Al than P. quinquefolium. P. quinquefolium contained more of Rbl and Rd of protopanaxadiol saponin, and less or Re, $Rg_1$ and $Rg_2$ of protopanaxatriol saponin than P ginseng. However, no Rf was detected in the p. quinquefolium. Key words Panax ginseng, Panax quinquefolium, ginseng character, ginsenoside.

The composition and concentration of ginsenosides and the free sugars in panax ginseng(Korea ginseng), panax quinquefolium (American ginseng) and panax pseudoginseng var. notoginseng (Sanchi ginseng), were investigated. The major ginsenosides and the order of their amount in panax ginseng are Rbl, Rc Rgl, Re, Rb2 Rd and these are about 90% of total ginsenosides, but major ginsenosides of American and Snachi ginseng art Rbl, Re, Rg1 (about 91% of total) ansi Rgl, Rbl, Re (about 93% of total) respectively. Sanchi ginseng was observed in higher concentration of panaxatriol than panaxadiol unlike panax and American ginseng. Free sugars in white ginseng are fructose, glucose, maltose and sucrose. Whereas, in red ginseng rhamnose and xylose were also detected as free sugar.

The content and composition of saponin compounds of Panax species were analyzed according to their species, region and processing type of red and white ginseng. The species employed were Korean-, Chinese-, Japanese red ginsengs, and Korean white ginseng of Panax ginseng, American- and Canadian ginsengs of Panax quinquefolium, and Panax notoinseng. Twelve main saponin components in the ginseng were identified and quantified using TLC and HPLC. All three species had remarkably different content and composition. However, within each species they were similar. Twelve major ginsenosides were determined in P. ginseng, eight in p. quinquefolium, and six in P. notoginseng. Of the components of P ginseng Rf, $Rh_1$, $Rh_2$ and Ra were not detected in P quinquefolium, and $Rb_2$, Rc, Rf, $Rh_2$, Ra and Ro not detected in P. notoinseam. Crude saponin content and protopanaxadiol/protopanaxatriol saponin ratio were compared. They were 4.81~5.24% and 1.27~ 1.45 in p. ginsengs, 7.01~7.25% and 2.12~ 2.15 in p. quinquefolium, 9.80% and 0.99 in P. notoineng. The prosapogenin and sapogenin content were different among the Panax species.

Discriminating between two herbal medicines (Panax ginseng and Panax quinquefolius), with similar chemical and physical properties but different therapeutic effects, is a very serious and difficult problem. Differentiation between two processed ginseng genera is even more difficult because the characteristics of their appearance are very similar. An ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF MS)-based metabolomic technique was applied for the metabolite profiling of 40 processed P. ginseng and processed P. quinquefolius. Currently known biomarkers such as ginsenoside Rf and F11 have been used for the analysis using the UPLC-photodiode array detector. However, this method was not able to fully discriminate between the two processed ginseng genera. Thus, an optimized UPLC-QTOF-based metabolic profiling method was adapted for the analysis and evaluation of two processed ginseng genera. As a result, all known biomarkers were identified by the proposed metabolomics, and additional potential biomarkers were extracted from the huge amounts of global analysis data. Therefore, it is expected that such metabolomics techniques would be widely applied to the ginseng research field.

Comparative cytotoxic activities of petroleum ether soluble fraction from various ginsengs of Panax species were evaluated using A549 (human lung adenocarcinoma) and SK-OV-3(human ovary carcinoma) cancer cell lines. Korean red ginseng, Korean white ginseng, American ginseng and Canadian ginseng were found to show more potent cytotoxicitles on A549 and SK-OV-3 cell lines than Chinese red ginseng, Japanese red ginseng and Sanchi ginseng. It is noteworthy that especially, red ginseng prepared from the root of Panax ginseng cultivated in Korea shows relatively stronger cytotoxic activities than those cultivated in China and Japan.
