  • The purpose of this study is to develop a new preparation process of American ginseng (Panax quinquefolium) extract featuring high concentration of ginsenoside $Rg_3$, $Rg_5$, and $Rk_1$, Red ginseng special components. Chemical transformation from ginseng saponin glycosides to prosapogenin was analyzed by the HPLC. Extracts of American ginseng were processed under several treatment conditions of microwave and vinegar (about 14% acidity). The results showed that the quantity of ginsenoside $Rg_3$ increased by over 0.9% at the 20 minutes of the pH 2~4 vinegar and microwave American ginseng ethanol extract compared with other process times. The result of MAG-20 indicates that the American ginseng microwave and vinegar-processed American ginseng extracts (about 14% acidity) treated for 20 minutes produced the highest amount of ginsenoside $Rg_3$ (0.969%), $Rg_5$ (1.071%), and $Rk_1$ (0.247%). Besides, MAG-15 indicates that the microwave - and vinegar-processed American ginseng extracts (about 14% acidity) treated for 15 minutes produced the highest amount of ginsenoside $Rg_3$ (0.772%), $Rg_5$ (1.330%), and $Rk_1$ (0.386%). This indicates that American ginseng treated with microwave and vinegar had the quantity of the ginsenoside $Rg_3$ over 32 times the amount of the ginsenoside $Rg_3$ (which was not found in raw and American ginsengs) in the average commercial Red ginseng.

  • It was reported that Red ginseng contains specific ginsenoside-Rg$_2$,-Rg$_3$,-Rh$_1$and -Rh$_2$, which show various pharmacological effects. However, production of these specific ginsenosides from Red ginseng is not commercially applicable because of high cost of the raw material, roots. This work was carried out to examine the production of Red ginseng specific ginsenosides from Agrobacterium-transformed hairy roots. Hairy roots were induced from 3 year-old root segment of Korean ginseng (Panax ginseng C.A. Meyer) after infection with Agrobacterium rhizogenes A4. Among many lines of hairybroots, KGHR-8A was selected. Steam heat treatment of hairy roots was resulted in the changes of ginsenoside composition. Eleven ginsenosides were detected in heat-treated hairy roots but eight in freeze dried hairy roots. In heat treated hairy root, content of ginsenoside-Rb$_1$,Rb$_2$,Rc, Rd, Re, Rf, and Rg$_1$were decreased compared to those of freeze dried hairy roots. However, heat treatment strongly enhanced the amount of Red ginseng specific ginsenogides (ginsenoside-Rg$_2$,-Rg$_3$,-Rh$_1$and -Rh$_2$). Amounts of ginsenoside-Rg$_3$,-Rh$_1$and -Rh$_2$ in heat-treated hairy roots were 2.58, 3.62 and 1.08 mg/g dry wt, respectively, but these were detected as trace amount in hairy roots without heat treatment. Optimum condition of heat treatment for the production of Red ginseng specific ginsenoside was 2 h at 105$^{\circ}C$. This result represents that Red ginseng specific ginsenoside can be producted from hairy roots by steam heat treatment.

  • Cooking basic information for indexing of fresh ginseng roots (Panax ginseng C. A. Meyer) was determined. Ginsenoside contents of various age fresh ginseng roots cultivated in Northeast Asia were quantitatively analyzed by HPLC. Average contents of total saponin and each ginsenoside of 4-year-old fresh ginseng root cultivated in Korea were higher than those cultivated fur longer periods (5- and 6-year-old). One-way analysis variance showed average contents of total saponin and each ginsenoside of 4-, 5-, and 6-year-old fresh ginseng roots were not statistically significant. Four-year-old fresh ginseng root cultivated at Geumsan, Korea contained the highest ginsenoside content among samples studied.

  • The purpose of this study was to develop a new preparation process of ginseng extract with the high concentration of prosapogenin, the specific component in Red ginseng. Chemical transformation from the ginseng saponin glycosides to the prosapogenin was analyzed by the HPLC. The extracts of ginseng leaf and stem were processed at the several treatment conditions of the microwave and vinegar(about 14% acidity). MGLS-20 findings show that the ginseng leaf and stem extracts that had been processed with microwave and vinegar for 20 minutes peaked in the level of ginsenoside $Rg_3$(0.906%). MGLS-25 peaked in the level of ginsenoside $Rg_5$(0.329%) in the ginseng leaf and stem extract processed with microwave and vinegar for 25 minute. And the other kinds of ginseng prosapogenin did not show a higher content.

  • This study was to obtain essential information that can be used to index Notoginseng Radix(Panax notoginseng, Sanchi) cultivated in Winnan, China. The ginsenoside contents in various Sanchi on various parts and ages were quantitatively analyzed by HPLC. The average of total saponin and the ginsenoside contents of each 3-year-old Sanchi cultivated in China were higher than those of the Sanchi for longer period. As a result, the order of the total saponin contents was 3-year-old (7.13%), 4-year-old (6.27%), 5-year-old (5.34%), and 6-year-old (4.06%) Sanchi. On the other hand, the total saponin average and the ginsenoside contents of each of the fine roots, lateral roots, and rhizomes of Sanchi cultivated in China were similar to the 6-year-old Sanchi.

  • This study was conducted to compare the contents of ginsenoside according the water extract conditions of red ginseng. In method A, red ginseng extract was prepared at $75^{\circ}C$ for 18 hours by 1 time extraction, and method B, the preparation was done at $85^{\circ}C$ for 18 hours by 1 time extraction. In method C, the primary extract prepared at $75^{\circ}C$ for 9 hours was blended with the secondary extract prepared by re-extracting the red ginseng residue obtained after the primary extraction, at $85^{\circ}C$ for 9 hours. Method D was the same procedure as method C but the extraction temperature for the primary extraction was $85^{\circ}C$ and that for the secondary extraction was $95^{\circ}C$. The contents of total and $Rb_1$, $Rg_1$ and $Rg_3$ ginsenoside were highest in Method C. The content of prosapogenin (ginsenoside $Rg_2$, $Rg_3$, $Rb_1$ and $Rb_2$) was highest in Method B. There was no consistent tendency in Brix, pH, Hue value and absorbance among extraction methods.

  • This study was carried out to investigate the difference of ginsenoside compositions in crude ginseng saponins prepared by five different methods including three new methods. Two known methods are hot methanol(MeOH) extraction/n-butanol(n-BuOH) fractionation and hot MeOH extraction/Diaion HP-20 adsorption/MeOH elution. Three new methods are hot MeOH extraction/cation AG 50W $absorption/H_2O$ elution/n-BuOH extraction, cool MeOH extraction/Diaion HP-20 adsorption/MeOH elution and direct extraction with ethyl acetate(EtOAc)/n-BuOH. Analysis of ginsenoside composition in the crude saponins by conventional HPLC/RI(Refractive Index) did not show great difference between methods except EtOAc/n-BuOH method. However, HPLC/ELSD (evaporative light scattering detector) employing gradient mobile phase afforded fine resolution of ginsenoside Rf, $Rg_1$ and $Rh_1$, and great difference of ginsenoside compositions between methods. LC/MS revealed that large amount of prosapogenins were produced during the pass through the cation exchange (AG 50W) column being strongly acidic. Six major ginsenosides such as $Rb_1,w;Rb_2,$ Rc, Rd, Re and $Rg_1$, 5 prosapogenins and one chikusetsusaponin were identified by LC/MS. A newly established HPLC method employing ODS column and gradient mobile phase of $KH_2PO_4/CH_3CN$ revealed that malonyl ginsenosides were detected only in the crude saponin obtained from cool MeOH extraction.

  • The purpose of this study was to develop a new preparation process for chemical transformation of ginseng saponin glycosides to prosapogenins. Ginseng and ginseng extracts were processed under several treatment conditions using ascorbic acid solution. Treating with ascorbic acid at pH 2-3 and above $80^{\circ}C$ increased the ginsenoside $Rg_3$ content of samples to over 3% as compared to other pH levels and temperatures. In addition, ginseng and ginseng extracts that were processed under a high ascorbic acid solution treatment condition (pH 2.0, 5 hr) contained more ginsenoside $Rg_3$ (approximately 16 times) than those processed under a low ascorbic acid solution treatment condition (pH 3.0, 5 hr). The highest quantity of ginsenoside $Rg_3$ (3.434%) occurred when a sample of fine ginseng root extract (AG2-9) was processed with the ascorbic acid solution at pH 2.0 for 9 hr. However, there was no change in the amount of ginsenoside $Rg_3$ when fine ginseng root extracts were processed with ascorbic acid solution at pH 2.0 for over 9 hr. In conclusion, the results indicated that ascorbic acid treatment of ginseng extracts can produce a level of ginsenoside $Rg_3$ that is over 90-fold the amount found in commercial red ginseng.
