  • A new rapid saponin extraction method was developed with using of organic solvent and waring blonder. There was a good correlation between previous distillation method and this method in f major ginsenosides ($Rb_1$, $Rb_2$, Rc, Rd, Re, Rg1) contents. When the ratio of methanol and chloroform was 7:3, this method showed similar saponin contents (total major. ginsenosides contents) comparing with distillation method. Contents of total major ginsenosides were 2.41% in this method and 2.54% in distillation method. However, crude saponin content of this method was higher than that of distillation method.

  • Ginsenosides (ginseng saponin) as the one of important pharmaceutical compounds of ginseng and is responsible for the pharmacological and biological activities. These ginsenoside produces diverse small molecules ginsenoside which have more pharmacological activities including anti-wrinkle, anti-cancer and anti-oxidant effects. In the present study, we isolated bacteria using esculin agar, to produce ${\beta}$-glucosidase, and we focused on the bio-transformation of ginsenoside. Phylogenetic tree analysis was performed by comparing the 16S rRNA sequences; we identified the strain as Stenotrophomonas rhizopilae strain GFC09. In order to determine the optimal conditions for enzyme activity, the crude enzyme was incubated with 1 mM ginsenoside $Rb_1$. Bioconversion of ginsenoside $Rb_1$ were analyzed using TLC and HPLC. The crude enzyme hydrolyzed the ginsenoside $Rb_1$ along the following pathway: LB: $Rb_1{\rightarrow}Rd{\rightarrow}F_2$ into compound K, TSB: $Rb_1{\rightarrow}Rd{\rightarrow}F_2$. The structure of the hydrolyzed metabolites were identified by NMR. The activity screening tests showed that the conversion product induced the production of type I procollagen in a dose-dependent manner. These results suggested that hydrolyzed ginseng product containing the ginsenoside $F_2$ and compound K could be useful as an active ingredient for wrinkle-care cosmetics.

  • To study of production of Panax ginseng leaf tea, after harvested the leaves in July, August, and September as ripening season, the content and composition of ginseng saponin were investigated. 1. Crude saponin contents in the leaves were a about 16.5%, and they were found to be lower in the leaf harvested in September than those harvested in July or August. 2. As similar patterns were observed with month to month in ginsenoside, sum of major ginsenosides of -Re, -Rd and -Rg1 was fixed about 70% of saponin at harvested in each month. And minor components were ginsenoside -Rb1, -Rb2 and -Rc as in order. 3. The ratio of protopanaxadiol(PD)/protopanaxatriol(PT) was revealed reduction of 1.13 of harvested in July to 0.85 of those in September gradually. The contents of protopanaxadiol were high in the leaves of August and protopanaxatriol was high in those September.

  • This study was conducted to investigate the changes in saponin content and antioxidant activity of crude ginseng and extruded ginseng by using different solvent extraction methods. Each of the fractions was first extracted by 80% ethanol followed by ether treatment to remove the lipid components. Water soluble components were separated by ethylacetate and water saturated butanol. Four fraction, including 80% ethanol, ethylacetate, butanol and water were obtained from crude and extruded ginsengs to analyze saponin content and antioxidant activity. Saponin content and antioxidant capacity of each of the four fractions were measured by LC/MS analysis and ORAC(Oxygen Radical Absorbance Capacity) assay, respectively. It was found that a major portion of saponin was present in ethyl acetate and water saturated butanol fractions. When extracted by 80% ethanol, ginsenoside Rb1 and Rg1 were mostly found in crude ginseng, while ginsenoside Re and Rb1 were detected in extruded ginseng. Even though Rh1 and Rg3 were found in a very small quantity in crude ginseng, there was a significant quantity of both in extruded ginseng when extracted by 80% ethanol. Similar tendency was also observed in extruded ginseng fraction when extracted with ethyl acetate and butanol. In crude ginseng, the level of Rg1 was the highest among other ginsenosides upon extraction by ethyl acetate, while Rh1 and Rg3 were predominantly found by employing similar solvent extraction in the extruded ginseng. Also, Rg1, Re and Rb1 were also found in the extruded ginseng with small quantity. Rg1, Re and Rb1 were found in crude ginseng by butanol extraction, while Rb1 and Re were extracted from the extruded ginseng. Overall, there was no difference in the saponin content between crude ginseng and extruded ginseng when extracted by butanol and water, but twice as much of saponin was obtained by 80% ethanol extraction and 6 times more saponin were obtained in ethyl acetate fraction in the extruded ginseng. Antioxidant capacity of crude ginseng as determined by ORAC assay was higher in 80% ethanol(high in many different kinds of biological compounds) and water saturated butanol(high in polar saponin) fractions than the ethyl acetate and water fractions. No difference in antioxidant capacity was observed between crude and extruded ginseng. However, antioxidant capacity of ethyl acetate and water fractions in extruded ginseng was significantly higher than crude ginseng($P$ >0.05). All the fractions in both, crude and extruded ginseng possessed antioxidant capacity and even water fractions that contained almost no saponin had some antioxidant capacity. While determining correlation coefficient between fractions in extruded ginseng by Pearson correlation, it was observed that 80% ethanol fraction was in correlation with ethyl acetate($P$ >0.01) and ethanol($P$ >0.001) and in the case of ethylacetate, correlation was observed only with butanol fraction($P$ >0.05).

  • Major saponins in ginseng were analysed using reverse phase high performance liquid chromatography with binary mobile phase gradient control system instead of normal phase column. The optimum condition were as following : reverse phase column; ${\mu}{\beta}ondapak\;C_{18}$ column (Waters, $3.9mm{\times}300\;mm,\;5{\mu}m$), methyl cyanaide/water binary mobile phase gradient control system, solvent flow rate; 1.5 ml/min, and UV($203{\mu}m$ ) detector. The complete separation of ginsenoside $Rb_1,\;Rb_2,\;Rc,\;Rd,\;Re,\;Rf\;and\;Rg_1$ was achieved within 55 min. The Regression coefficients of the calibration curves for seven ginsenosides were 0.99.

  • In order to obtain the basic information for the development of ginseng varieties with high saponin contents. saponin contents and ginsenosides of Panax ginseng (Korean ginseng) and Panax quinquefolium (American ginseng) grown under the same environmental conditions were analysed. Crude saponin contents of root and aerial parts were more in Panax quinquefolium than in Panax ginseng, and aerial parts had more saponin contents in comparison with a root. Protopanaxatriol saponin was greatly more in the aerial parts of ginseng while more amount of protopanaxadiol saponins were detected in the root. As for the ginsenosides, the patterns of ginsenosides detected in total saponin of the aerial parts were not different between two species, Panax ginseng and Panax quinquefolium, but the root ginsenoside patterns were quite different. Ginsenosides such as Rg$_2$, R$_{f}$. R$_{a}$ and R$_{o}$ were not detected in the root of Panax quinquefolium (American ginseng).).).).

  • Saponins of ginseng root, leaf and stem were identified by TLC. Eleven unknown spots were detected in ginseng leaf and ten unknown spots in ginseng stem on TLC besides seven ginsenosides such as $ginsenoside-Rg_1,\;-Rf,\;-Re,\;-Rd,\;-Rc,\;-Rb_2,\;and\;-Rb_1$ which are contained in ginseng root. $Ginsenoside-Rg_3\;and\;-Rg_2$ were identified on TLC from mild hydrolysates with 50% acetic acid of total saponins from ginseng root, leaf and stem. Meanwhile, panaxadiol, panaxatriol and oleanolic acid were identified from hydrolysates with 7% ethanolic sulfuric acid of total saponin of ginseng root, while panaxadiol and panaxatriol from those of total saponins of ginseng leaf and stem.
