  • Recent studies have indicated that $\beta$-cell dysfunction and insulin resistance are important factors in the development of type 2 diabetes. The present study investigated the effect of extracts from different parts of white, Taegeuk, and red ginseng root on insulin-stimulated glucose uptake in muscle cells and proliferation of $\beta$-cells. Extracts of the fine roots of Taegeuk ginseng significantly enhanced glucose uptake compared with the control. White ginseng lateral root extracts enhanced insulin-induced glucose uptake. Proliferation of $\beta$-cells was significantly increased by Taegeuk ginseng main and lateral root extracts and by red ginseng lateral and fine root extracts. In conclusion, different root parts of white, Taegeuk, and red ginseng differentially affect glucose uptake and pancreatic $\beta$-cell proliferation.

  • This study intended to measure the desorption and adsorption EMC of four years old Peeled ginseng, Unpeeled ginseng and Taegeuk ginseng under various conditions$20^{\circ}C$, $30^{\circ}C$, $40^{\circ}C$, $50^{\circ}C$) and five levels of relative humidity from 31% to 88%) by the static method. Four widely used EMC models were selected and evaluated. Also the empirical model was evaluated. The results are summarized as follows ; 1) EMC difference between ginseng size was not found but found between ginseng species. EMC difference between Peeled ginseng and Unpeeled ginseng was not found. EMC of Peeled ginseng and Unpeeled ginseng was higher than that of Taegeuk ginseng. 2) The hysteresis, which is difference between desorption and adsorption EMC, was found. Desorption EMC was higher than adsorption EMC. The hysteresis at the same temperature decreased as relative humidity increase. The difference of hysteresis between Peeled ginseng and Unpeeled ginseng was not large and the hysteresis of Taegeuk ginseng was smaller than those of other species. 3) Among the selected models, Henderson model was the best to predict the adsorption EMC of White ginseng(Peeled and Unpeeled ginseng), and Oswin model was the best to predict the desorption EMC of White ginseng and the desorption and adsorption EMC of Taegeuk ginseng. The models are as follows ; (a) White ginseng(Peeled and Unpeeled ginseng) ${\circ}$ Desorption EMC(Oswin model) : $$M=(0.1272-0.0007420T){\cdot}[RH/(1-RH)]^{(0.4164+0.001368T)}$$ ${\circ}$ Adsorption(Henderson model) : $$1-RH={\exp}[-0.0003480T_k\;{M_o}^{0.9231}]$$ (b) Taegeuk ginseng ${\circ}$ Desorption EMC(Oswin model) : $$M=(0.1051-0.0008439T)[RH/(1-RH)]^{(0.4553+0.003425T)}$$ ${\circ}$ Adsorption EMC(Oswin model) : $$M=(0.08247-0.0007559T){\cdot}[RH/(1-RH)]^{(0.5760+0.005540T)}$$ 4) The developed empirical models could predict the desorption and adsorption EMC for White and Taegeuk ginseng more precisely than selected models. The empirical models are as follows ; (a) White ginseng(Peeled and Unpeeled ginseng) ${\circ}$ Desorption EMC : $$M=0.124-0.000647T-0.216RH+0.373RH^2$$ ${\circ}$ Adsorption EMC : $$M=0.0879-0.000663T-0.197RH+0.399RH^2$$. (b) Taegeuk ginseng ${\circ}$ Desorption EMC : $$M=0.159-0.000728T-0.429RH+0.565RH^2$$ ${\circ}$ Adsorption EMC : $$M=0.123-0.000662T-0.384RH+0.555RH^2$$.

  • This study was carried out to determine changes in general chemical composition, free sugars, physicochemical properties of extract, and ginsenoside contents depending upon processing methods. Ginseng roots harvested from the same field were employed for the processing into white ginseng (WG), taegeuk ginseng (TG), red ginseng A (RGA, steamed one time), and red ginseng B (RGB, steamed three times). The fat content decreased by increasing duration of treatment and number of steaming treatment. On the other hand, there was no significant variation in contents of ash and carbohydrate depending on processing methods. Contents of sucrose and maltose was higher in Taegeuk and red ginseng than those of white ginseng. Steamed ginseng root (taegeuk and red ginseng root) showed higher amount of water extractable solid than the unsteamed white ginseng, but the variation of crude saponin content was not distinctive depending on processing methods. The contents of total ginsenosides increased by the order of white, taegeuk, red A, and red B root. In summary, chemical composition and total ginsenoside content were different according to part of root and processing methods, thus implies the importance of quality control as well as pharmacological activity of ginseng root.

  • Ginsenoside composition and contents of Korean white and taegeuk ginsengs were investigated to establish Chinese pharmaceutical standards for import of Korean ginseng. Total ginsenoside-Rg1, Re, and Rb1 of all Korean white and taegeuk ginseng samples were higher than guideline of Chinese standard of 0.4%, $Mean{\pm}S.D.$ values of Rg1, Re, and Rb1 of Korean white ginseng were $232.7{\pm}110.2,\;235.3{\pm}101.5,\;and\;280.1{\pm}121.3\;mg%$, respectively. Ratio of Rg1 to Re of Korean white ginseng was 1.02. $Mean{\pm}S.D.$ values of Rg1, Re, and Rb1 of Korean taeguek ginseng were $262.1{\pm}127.2,\;213.1{\pm}55.7,\;and\;279.9{\pm}92.1\;mg%$, respectively.
