The effective component Ginsenoside in Ginseng has been widely used to cure some hypochondriasis and be as supplementary medicines. There are many chemical analysis methods to measure the contents of Ginsenoside in Ginseng; however, all these methods have some shortcomings such as long time, environmental pollution and damaging the samples. In this paper, it is possible to use near infrared spectroscopy to measure the content of Ginsenoside in Ginseng without destruction. As the results, Rg1, Rb1, Re and T-Saponin of Ginsenoside can be measured with the accuracy of R(0.81) SEP (1.704 mg/g), R(0.74) SEP (1.211 mg/g), R (0.78) SEP (1.049 mg/g) and R(0.84), SEP(4.537 mg/g).

This study compared the contents of ginsenoside according to the extract conditions of red ginseng to provide basic information for developing functional food using red ginseng. According to the result, the content of crude saponin was highest in 72 hours of extraction at $82^{\circ}C$ (RG-823). The content of prosapogenin (ginsenoside $Rh_1,\;Rh_2,\;Rg_2,\;Rg_3$) was highest in 48 hours of extraction, and followed by 72 and 24 hours at $82^{\circ}C$. And at $93^{\circ}C$ the prosapogenin contents were highest in the order of 48 hours, and next in 24 and 72 hours. In addition, ginsenoside $Rb_1,\;Rb_2$ Rc and Re were not detected in 72 hours of extraction at $93^{\circ}C$ (RG-933) presumedly due to hydrolysis, but ginsenoside Rd, Rf and $Rg_1$ were detected as long as 72 hours of extraction. These results show that protopanaxatriol group is relatively more resistant to heat than protopanaxadiol group.

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 done for the determination of ginsenosides contents of Korean ginseng and ginseng products as well as the development of analytical method for ginsenosides. It is known that perfect segregation of ginsenoside Rg and Re is not easy, but in this study almost perfect segregation can be possible by the control of concentration between acetonitrile and water. Among Korean ginseng, ginseng powdered tea and red ginseng powdered tea, the highest ginsenosides content of sum of each 7 kind o ginsenoside was found in red ginseng powdered tae as 23,211${\mu}g$ per 1g/dw The ginsenoside content of ginseng powdered tea was lower than red ginseng powdered tea as 15,217${\mu}g$ per 1g/dw Total ginsenoside content in the root of ginseng was 29,268${\mu}g$ per 1/dw Each amount of ginsenoside contained in ginseng root was in the order of Rb1, Rg1, and Rc. It was shown that there was difference in constitutional element of ginsenosides in ginseng powdered tea and ginseng root.

With the purpose of improving ginsenoside content in adventitious root cultures of Korean wild ginseng (Panax ginseng Meyer), the roots were treated with different dosages of ${\gamma}$-ray (5, 10, 25, 50, 75, 100, and 200 Gy). The growth of adventitious roots was inhibited at over 100 Gy. The irradiated adventitious roots showed significant variation in the morphological parameters and crude saponin content at 50 to100 Gy. Therefore, four mutant cell lines out of the propagation of 35 cell lines treated with 50 Gy and 100 Gy were selected on the basis of phenotypic morphology and crude saponin contents relative to the wild type control. The contents of 7 major ginsenosides ($Rg_1$, Re, $Rb_1$, $Rb_2$, Rc, Rf, and Rd) were determined for cell lines 1 and 3 from 100 Gy and lines 2 and 4 from 50 Gy treatments. Cell line 2 showed more secondary roots, longer length and superior growth rate than the root controls in flasks and bioreactors. Cell line 1 showed larger average diameter and the growth rate in the bioreactor was comparable with that of the control but greater in the flask cultured roots. Cell lines 1 and 2, especially the former, showed much more ginsenoside contents than the control in flasks and bioreactors. Therefore, we chose cell line 1 for further study of ginsenoside contents. The crude saponin content of line 1 in flask and bioreactor cultures increased by 1.4 and 1.8-fold, respectively, compared to the control. Total contents of 7 ginsenoside types ($Rg_1$, Re, $Rb_1$, $Rb_2$, Rc, Rf, and Rd) increased by 1.8 and 2.3-fold, respectively compared to the control. Crude saponin and ginsenoside contents in the bioreactor culture increased by about 1.4-fold compared to that the flask culture.

인삼 (Panax ginseng C.A. Meyer)의 뿌리로부터 유도 인삼모상근을 이용한 무기이온 흡수과정의 상승 및 길항작용에서 phosphorus (P $O_{4}$$^{-}$)와 nitrogen source (N $H_{4}$$^{+}$, N $O_{3}$$^{-}$)의 증가는 조직 내에 $Mg^{2+}$ 및 F $e^{2+}$ 의 흡수를 증가시키는 원인으로 확인되었다 특히, ammonium의 농도를 4배 높일 경우 F $e^{2+}$의 흡수는 13 mg/L, C $u^{2+}$의 흡수는 0.32mg/L이 증가하여 각각 47.5%와 123.1%로 현저한 이온흡수의 상승효과를 초래하였다. 이러한 결과는 인삼포장에서 인산과 질소원의 과도한 시비는 생장을 다소 증가시키고 뿌리의 철이온과 2가 무기이온 흡수도 증가시킴을 알 수 있다 유리당의 함량은 유리당의 종류에 따라 인산과 질소원의 최적 농도가 다르게 나타났다. 반면에 ginsenoside함량은 인산과 질소원 모두 가장 낮은 농도에서 가장 높았다. 인산의 경우에는 1/2 MS배지의 농도 (0.62 mM)보다 낮은 0.31 mM에서 R $b_2$는 44.7%, Rc는 29.9%가 높았다. Ammonium은 1/2 MS 배지 (10.30 mM)보다 낮은 5.15 mM에서 R $b_2$와 Rc를 각각 21.7%와 31.9% 그리고 nitrate 역시 1/2 MS배지 (9.4mM)보다 낮은 4.70 mM 에서 각각 17.6%와 25.5%의 뚜렷한 함량증가를 나타냈다. 질소원에 따른 ginsenoside 함량 증가에서는 N $H_{4}$$^{+}$가 N $O_{3}$$^{-}$보다 다소 효과적이었다. 따라서 인삼모상근의 ginsenoside생산을 높이기 위해서는 인산과 질소원의 농도를 조절한 새로운 배지가 적합한 것으로 확인되었다.

Objectives This study was conducted to investigate the beta-glucan, ginsenoside content, antioxidant activity and safety of modified Kyungohkgo added to Sparassis crispa and Hericium erinaceum. Methods The marker compounds contents, antioxidant activity and safety of modified Kyungohkgo were tested. The contents of beta-glucan and ginsenoside Rb1, Rg1, and Rg3 marker compounds were measured, the antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, and a safety test was conducted via single dose toxicity assessment. Results Analyzing the contents of marker compounds showed 351.75 mg/g of beta-glucan, 0.0327 mg/g of ginsenoside Rb1 and 0.0802 mg/g of ginsenosai Rg3. In the DPPH free radical scavenging activity, the inhibition concentration 50% of modified Kyungohkgo was 0.2880%. The scavenging activity of modified Kyungohkgo was 5.49% activity at 0.05% concentration, 89.66% activity at 0.5% concentration, 94.68% activity at 1% concentration, and 96.06% activity at 5% concentration. In the single dose toxicity test of modified Kyungohkgo, a dose of 2,000 mg/kg B.W. was set at its highest capacity and observed after oral administration to female and male rats. No toxicological findings were recognized. It was observed that the resulting lethal dose can be set to 2,000 mg/kg B.W. or higher for both females and males. Conclusions The results of the experiment on modified Kyungohkgo showed that the marker compounds contents were beta-glucan and ginsenoside Rb1 and Rg3, that antioxidant activity was observed through the DPPH free radical scavenging activity, and safety was confirmed through the single dose toxicity assessment.
